The disadvantages of this invention are the lack of a programmed filling function, which complicates the control process, and the lack of a data transmission function, which complicates the process of obtaining, storing and transmitting data to the user about the technical condition of the installation and the water purification process.

The leak sensor generates an alarm only in the event of a water leak, which reduces its reliability, since information about high humidity is necessary for a timely response and additional diagnostics of the system.

The lack of a built-in printer does not allow the user to differentiate the sample and know exactly the time and quality of the collected water.

This system does not have an automated cartridge replacement program, which in turn is the process of replacing the filter cartridge, from pressure relief to final washing and commissioning.

The problem to which the invention is aimed is the creation of an automated device for a full cycle of water treatment.

The water purification complex is designed to remove unwanted chemical, biological contaminants and/or solid particles from water and ensures the purification of source water from suspended mechanical and colloidal particles, microorganisms, organic compounds and heavy metal salts through the combined use of several purification methods, including mechanical filtration , deionization, reverse osmosis and/or irradiation with ultraviolet light to supply laboratory equipment with water of various degrees of purification and produce water for working with drugs and reagents, as well as for carrying out various laboratory manipulations.

The hardware and software complex consists of the following components (Fig. 1):

- hydraulic unit, including filters, pipelines, fittings, storage tank (not shown in Fig. 1);

- control and data processing controller 1 with software and switching elements (relays, connectors);

- measurement unit 2, including leakage sensor 3, pressure sensors 4, water level sensors 5 in the storage tank, filter regeneration sensors 6, water flow sensor 7, conductivity sensors 20, temperature sensors 21;

- actuators 8, consisting of inlet and outlet water taps, valves 9 and pumps 10 controlled by current switches and relays located on the controller 1;

- control unit for ultraviolet lamp 11;

- water cooling fan 12;

- power supply 13;

- conductivity measuring device 14;

- filter regeneration (washing) control unit 15. The regeneration (washing) control unit is located on the filters. Power and control signals come directly from the controller;

- display and control unit 16;

- NFC 17 wireless communication module;

- remote communication module with an external information collection server based on GSM module 18;

- printer 19.

The software of the hardware complex in the control controller is a set of interconnected algorithms, the execution of which allows for the full implementation of all functions and is divided into two parts, depending on its location. One part of the software is located in the memory of the control controller, and the second part is located in the memory of the display and control unit.

The main algorithms located in the memory of the control controller are:

- algorithm for monitoring water parameters at the input of the hardware complex and at its output;

- algorithm for filling the storage tank of the hardware complex with water of the required quality;

- algorithm for maintaining the required water quality in the storage tank of the hardware complex;

- algorithm for regenerating filters of the hardware complex;

- algorithm for monitoring the state of pressure sensors of the input and output circuits of the hardware complex and water level sensors in the storage tank of the hardware complex;

- algorithm for monitoring the process of water selection from the storage tank of the hardware complex;

- algorithm for ensuring programmable water withdrawal from the storage tank;

- algorithm for interaction between the control controller and the display unit when displaying the state of the hardware complex and when transmitting control signals;

- algorithm for processing emergency situations;

- algorithm for interaction between the control controller and the display unit when transmitting data through a remote communication unit (GSM module) to the information collection server;

- algorithm of operation of the hardware complex in manual control mode;

- algorithm of operation of the hardware complex in semi-automatic control mode;

- algorithm for working out maintenance operations of the hardware complex.

The main algorithms located in the memory of the display and control unit are:

- algorithm for switching operating modes of the hardware complex (operating mode, manual control mode, semi-automatic control mode), as well as returning the hardware complex from sleep to operating mode;

- an algorithm for displaying the current state of the hardware complex, including the quality of water produced, water consumption by users, filter wear, condition of valves and pumps, and the amount of water in the hardware complex;

- an algorithm for displaying the configuration parameters of the hardware complex and providing the ability to adjust these parameters;

- algorithm for displaying the hydraulic circuit of the hardware complex in real time with display of water quality parameters;

- algorithm for displaying emergency situations;

- an algorithm for displaying the state of sensors and providing control over the state of valves and pumps in manual control mode of the hardware complex;

- an algorithm for displaying the state of valves and pumps and providing control of sensors in the mode of semi-automatic control of the hardware complex;

In its most general form, the operating algorithm when turning on the hardware complex is as follows.

1) monitoring the state of water level sensors in the storage tank of the hardware complex. If the water level is below the permissible level, then the hardware complex switches to the water PRODUCTION mode, otherwise the hardware complex switches to the mode of maintaining the water quality in the storage tank at the required level (circulation mode);

2) in the circulation mode, water is pumped through the output circuit of the hardware complex using a pump through a biofilter, an ultraviolet lamp and, if necessary, through a water cooling fan. When in this mode for 10 minutes and provided that the water quality meets the required level, the hardware complex goes into sleep mode, that is, the pump turns off and water pumping stops. After 1 hour, the hardware complex switches back to circulation mode and the cycle repeats.

If it is necessary for personnel to draw water, the sleep mode can be interrupted by touching the display of the hardware complex display unit or by touching the manual water filling button. If during the process of water selection its level drops below the permissible level, then the hardware complex switches to the water PRODUCTION mode;

3) the water PRODUCTION mode begins with flushing the pipelines and discharging water. Then, when the water pressure in the input circuit reaches the required level, the pump turns on and water is pumped through the membrane filter into the storage tank of the hardware complex. When the required water level is reached in the storage tank of the hardware complex, the water supply stops and the hardware complex again switches to circulation mode.

When the time comes to switch to the regeneration mode, the hardware complex is switched to circulation mode and the filter regeneration equipment is started. If at the time of starting regeneration the hardware complex is in the water PRODUCTION mode, then the water supply stops and the hardware complex is switched to circulation mode.

When the time comes to transfer data to the server, a communication session between the remote communication unit (GSM module) of the hardware complex and the information collection server is initiated and data is transferred to the server. In the event of an emergency, a communication session with the server is established at the moment the information is detected and all necessary information is transmitted to the server to identify the nature of the malfunction. In addition, the server further forwards this information to the personnel servicing this hardware complex.

When water is collected, personnel are given the opportunity to print an accompanying receipt containing the following information: date and time of water collection, amount of water, conductivity and temperature of the water.

In the process of developing algorithms, the state of the sensors of the hardware complex is constantly analyzed in order to detect and prevent emergency and abnormal situations. These include:

- water leakage, established by means of a leakage sensor, which sends a signal to the controller, which in turn sends a signal to close the water supply valve from the water supply system, turning off all pumps and valves of the device. At the same time, information about the accident that attracts the attention of personnel is displayed on the display unit, indicating its cause, and an intermittent sound signal is given.

- malfunction of any of the level sensors, as a result of which the controller sends a signal to turn off all pumps and valves of the hardware complex. At the same time, information about the accident that attracts the attention of personnel is displayed on the display unit, indicating its cause.

The software and hardware complex contains the first and second circuits, where the first main circuit of sequentially located filters, while the flow of purified water is forcibly pumped into the storage tank by means of a pump and goes to the outlet and distribution to the consumer after passing through the stages of additional purification, and the second circuit operates in CIRCULATION mode and contains a storage tank, a pump, final cleaning filters and a temperature stabilization device.

Similarly, the control action on the actuators is supplied by the controller in the following cases:

- low pressure in the inlet circuit (lack of water in the water supply);

- low pressure in the outlet circuit;

- lack of circulation in the output circuit;

- inability to achieve the required water quality in the outlet circuit;

- the quality of water in the input circuit is below the permissible limit;

- high pressure in the inlet or outlet circuit in cases where the condition of valves and pumps requires low pressure.

The software and hardware complex has the following set of functions:

- ensuring the production of high-quality water with a conductivity of no more than 0.1 mS/cm from tap water;

- providing a simple and convenient interface for users;

- providing the possibility of manual and programmable water filling;

- ensuring blocking of water supply from the water supply system, turning off all pumps and closing all valves in the event of emergency situations - water leakage, failure of level sensors, pressure sensors, etc.

- ensuring regular regeneration of filters and adjustment, if necessary, of the mineral composition of water with the possibility of changing the frequency and time of this operation;

- ensuring remote monitoring of the state of the hardware complex, the quality of water at the entrance and exit of the complex, clean water consumption, residual life of filters and the occurrence of emergency situations;

- provision of all necessary equipment and software for quick and convenient commissioning and maintenance of the complex.

Control and processing controller 1 is a switch for all devices connected to it. He contains:

- secondary power source (pulse converter DC 12v to DC 5v) with wiring;

- a central processor module based on the ATMEGA 2560 controller with wiring;

- real-time clock chip with backup battery;

- leakage sensor signal converter microcircuit;

- sound converter;

- relay for controlling the ultraviolet disinfection lamp;

- scheme for controlling the keys of actuators;

- connectors and terminal blocks for connection with all listed control devices.

Measurement unit 2 includes a leakage sensor 3, pressure sensors 4, water level sensors 5 in the storage tank, filter regeneration sensors 6, water flow sensor 7, conductivity sensors 20 and temperature sensors.

Leakage sensor 3 is a plate made of ABC plastic with electrodes and a connecting cable. The sensor is located under the installation on the floor to monitor possible emergency water leakage. When moisture appears on the sensor electrodes, the signal is sent to the controller, where it is converted into an alarm signal, followed by shutting down all installation systems and shutting off the water supply to the installation.

Pressure sensors 4 are membrane sensors with normally open contacts (in the absence of pressure, the contacts are open). Signals from the sensors are sent to the controller for further processing.

Water level sensors 5 in the storage tank are float-magnetic sensors with a normally open reed contact (if there is no water in the tank, the sensor contacts are open). Signals from the sensors are sent to the controller for further processing.

Regeneration sensor 6 is an electronic control device for the automatic filter regeneration flush valve. From the controller, power is supplied to the filter regeneration control units 15, as well as a signal to start filter regeneration at the scheduled time. If regeneration starts successfully, a regeneration confirmation signal is returned from the filter control unit to the controller.

Flow sensor 7 is a snail-vane type water meter with a “hall” element. The sensor is powered and data is collected from the controller. The sensor is designed to determine the presence of water flow in the circulation circuit and control the collected water.

The control unit for the ultraviolet disinfection lamp 11 is an electronic choke and is activated by closing the contacts of the electromagnetic relay and supplying AC 220 volts to the controller.

The power supply 13 is designed to power the low-voltage part of the electronic equipment. The power supply is a pulse voltage converter in a separate housing. Input voltage AC 220 volts, output voltage DC 12 volts / 100 watts.

The 14 two-channel conductivity measuring device (measuring cell) is designed to determine the electrical conductivity of prepared water in the flow at the outlet of the reverse osmosis (channel 1) and in the circulation circuit (channel 2). The water temperature in each channel is also measured separately in order to make a temperature correction of the conductivity readings. Logical control of the conductivity measurement unit is carried out by the controller.

The measurement limits of channel 1 are 0…200 µS/cm.

Measurement limits 2 channels - 0…18.2 MOhm/cm.

Temperature range - 0…50 °C

The measuring cell provides thermal correction of readings on both channels (if necessary, with the ability to turn off). Data on conductivity and temperature readings via both channels are sent to the controller and then to the indication and control unit.

To control valves, taps and pumps, actuators 8 are used (pulse-width load control method). This method made it possible to flexibly adjust the power characteristics of pumps and valves. At the moment the valve or pump is turned on, full power is supplied to the device; after a set time, the power is reduced to the required threshold for keeping the valve in the on state, as a result reducing heating of the valves and energy consumption in general. The power of the pumps is also regulated.

The display and control unit 16 consists of a monitor board, a color display, and a touch sensor (button) for manual water filling. The indication and control unit is designed to indicate the status of the installation, control all functions of the installation, as well as for programmable water supply.

The wireless communication module (NFC) 17 is designed for password-free access to the system for the purpose of carrying out maintenance of the installation, replacing cartridges and other equipment. Access is provided using an NFC card (tag).

Wireless communication module 18 (GSM) is designed to transmit information via a cellular network about the status of the installation in all parameters and signal an emergency (if it occurs).

Printer 19 is a receipt ribbon printer, ribbon width 58mm. The printer is designed to document the parameters of the collected water and the technical condition of the installation. Communication with the controller is carried out via the UART interface.

Operating the device

Primary water preparation is carried out by a cascade of filter elements consisting of F1, F2 and F3 (Fig. 2).

Coarse filter F1. Designed for primary filtration of water coming from the city water supply network in order to remove inclusions larger than 100 microns. The water flow follows from the inlet pipe inside the filter housing through a mesh placed in the filter housing flask, which selectively retains particles larger than the established nominal size. The flow follows to the outlet pipe and is directed to the pipe next to the filtering equipment located. The filter is equipped with a drainage system and automatic washing system.

Coarse filter: the water flow follows from the inlet pipe inside the filter housing through a mesh placed in the filter housing flask, which selectively retains particles larger than the established nominal size. The flow follows to the outlet pipe and is directed to the pipe next to the filtering equipment located. The filter is equipped with a drainage system and an automatic washing unit.

Next, the water flow enters the automatic iron removal filter F2: the water flow from the inlet pipe of the automatic control valve is directed to the upper layer of filter material loaded into the pressure housing. Then, passing through a layer of filter material, the water flow is freed from inclusions of the ferrous group and enters the lower mesh of the water-lifting tube. Then the water-lifting tube is directed to the automatic control valve, from which the outlet water is directed through the pipe to the next filtering device.

Next, the flow of filtered water passes through the ion exchange filter F3: the flow of water from the inlet pipe of the automatic control valve is directed to the upper layer of filter material loaded into the pressure housing. Then, passing through a layer of filter material, the water flow is freed from the elements of the hardness group and enters the lower mesh of the water-lifting tube. Then the water-lifting tube is directed to the automatic control valve, from which the outlet water is directed through the pipe to the next filtering device.

Regeneration (washing) of filters

To flush the coarse filter, the automatic flushing device is activated, opening the drainage channel. In this case, the resulting pressure difference moves the filter insert entirely downward until the lower part of the mesh is completely isolated from unfiltered water. At the same time, the supply of unfiltered water to the upper (“flushing”) part of the insert begins. The amount of water required to flush the filter enters through the upper part of the mesh into the turbine of the hydraulic flushing mechanism installed inside the insert with nozzles made according to the “Venturi tube” principle. The water coming out of the nozzles under pressure spins the turbine and washes away contaminants from the working part of the mesh, thus backwashing the filter mesh with filtered water. At the same time, the washing part of the mesh is cleaned, operating on a similar principle. When the drainage channel located at the bottom of the flask is closed, the pressure inside the flask stabilizes, and the insert, under the influence of a spring, returns upward again to its working position.

The automatic iron removal filter is controlled by an automatic valve controller. Based on a timer signal, the filter switches to the washing mode, which consists of 3 phases.

The first phase is backwashing, during which the hydraulic flow is directed as follows: after the inlet pipe it follows into the central pipe and, reaching the bottom, passes through the filter material, carrying with it the impurities and inclusions accumulated during filtration, breaking up the dense compressed layers of materials, thereby removing the channels formed during the filtration process. Next, the flow reaches the automatic control valve, where it is directed into the drainage pipe of the filter. The duration of this phase is determined by the automatic filter timer settings. The timer then moves the automatic control valve to the Filter Media Press position.

The second phase is pressing of the filter material, during which the hydraulic flow is directed from the inlet pipe to the top layer of the filter material. The lack of flow into the outlet and drain pipes helps compact the filter material to provide better filtration conditions. The duration of this phase is determined by the automatic filter timer settings. The timer then moves the automatic control valve to the Direct Flush position.

Third phase - Direct flushing during which the hydraulic flow is directed from the inlet pipe to the top layer of filter material. Then, passing through a layer of filter material, the water flow enters the lower mesh of the water-lifting tube. After that, it is sent through the water-lifting tube to the automatic control valve, from which it is sent to the drainage pipe and then sent to the drainage system. The duration of this phase is determined by the automatic filter timer settings. The timer then moves the automatic control valve to the FILTRATION position.

An automatic ion exchange filter is used to remove elements that determine hardness. Controlled by an automatic valve controller. Based on a timer signal, the filter goes into regeneration mode, which consists of 7 phases.

The first phase is Backwashing, during which the hydraulic flow is directed as follows: after the inlet pipe it follows into the central pipe and, reaching the bottom, passes through the filter material, loosening it, ensuring free washing of the granules in subsequent phases of the process. Next, the flow reaches the automatic control valve, where it is directed into the drainage pipe of the filter. The duration of this phase is determined by the automatic filter timer settings. The timer then moves the automatic control valve to the Saline Irrigation position.

The second phase is Irrigation of the filter material with a salt solution, during which the hydraulic flow is directed from the inlet pipe to the upper layer of the filter material. The vacuum area formed in the area of the ejector pump ensures the flow of salt solution into the pipe from the salt tank T3, then the solution is mixed with the flow of inlet water and enters the upper layers of the filter material, and passing through its layer, enters the water-lifting tube and follows the automatic control, where, in turn, through the drain pipe it is sent for drainage. At the end of the time allotted for this phase, the timer switches the automatic control valve to the exposure phase.

Third phase - Saline exposure, determined by the automatic valve timer. It is necessary for regeneration of the ion exchange properties of the filter material. The timer time is set during the equipment setup process during commissioning. At the end of the time, the automatic control valve enters the fast flushing phase.

The fourth phase is Direct flushing, during which the hydraulic flow is directed from the inlet pipe to the top layer of filter material. Then, passing through a layer of filter material, the water flow enters the lower mesh of the water-lifting tube. After that, it is sent through the water-lifting tube to the automatic control valve, from which it is sent to the drainage pipe and then sent to the drainage system. The duration of this phase is determined by the automatic filter timer settings. After which the automatic control valve moves to the next phase.

Fifth phase - Backwashing, during which the hydraulic flow is directed as follows: after the inlet pipe it follows into the central pipe and, reaching the bottom, passes through the filter material, loosening it, ensuring free washing of the granules in subsequent phases of the process. Next, the flow reaches the automatic control valve, where it is directed into the drainage pipe of the filter. The duration of this phase is determined by the automatic filter timer settings. After which the automatic control valve moves to the next phase.

The sixth phase is Direct flushing, during which the hydraulic flow is directed from the inlet pipe to the top layer of filter material. Then, passing through a layer of filter material, the water flow enters the lower mesh of the water-lifting tube. After that, it is sent through the water-lifting tube to the automatic control valve, from which it is sent to the drainage pipe and then sent to the drainage system. The duration of this phase is determined by the automatic filter timer settings. After which the automatic control valve moves to the next phase.

Seventh phase - Filling the brine tank. During this phase, the hydraulic flow, moving from the inlet pipe to the upper layer of the filter material, passes through its layers and, entering the lower mesh of the water-lifting tube, is directed to the automatic control valve, where it is discharged into the pipe to the salt tank T3. The duration of this phase is determined by the timer of the automatic control valve and depends on the settings of the regeneration characteristics of the filter. Upon completion of the filling phase of the T3 salt tank, the automatic control valve switches to filtration (operation) mode.

In particular cases, primary water treatment is optional and depends on the quality of the source water and the required parameters of the outlet water.

The production cycle of a ready-to-use installation begins with a strainer and a pressure regulator located on the section of the main line after the inlet water tap.

Through the collector lines, through the solenoid valve SV1 (Fig. 2), opened at the command of the controller, water enters the cartridge C1, then through the solenoid valve SV8 and the check valve RV3 it enters the cartridge C2, then through the pump P1, under the control of the LPS1 sensor, it is supplied to the cartridge M1. Adjustment of flows and pressures on the M1 cartridge is carried out by pressure reducing valve NV1. The control of the produced water is carried out by the temperature sensor TMP2 and the conductivity sensor CS 1, while regardless of the quality of the product, the first portion of the finished product is drained through the solenoid valve SV7 and, upon achieving the required quality, the water flow is switched to the storage tank T1 by opening the solenoid valve SV3 and closing SV7 . After reaching the upper level of the storage tank T1, the equipment is turned off in the reverse order and, upon completion of the shutdown process, the pre-treatment system is drained by briefly opening the solenoid valves SV2 and SV4.

After the storage tank T1 is completely filled and the CS2 sensor confirms that the product meets the required quality, the system switches to the “STORAGE” mode.

This mode provides for turning on and off the circulation of a clean circuit, as well as waiting and starting the next turn on (standby).

When the system is turned on, power is supplied to the solenoid valve SV10 and pump P2 at specified intervals, after which the state of the pressure sensor LPS 2 is monitored and the ultraviolet irradiator UF1 is turned on, then the temperature is monitored by the sensor TMP3 and, at the same time, the temperature stabilization device Cool1 is turned on (optional), made, for example, in the form of a water cooling fan. Next, the measurements of the conductivity sensor CS2 are monitored, and from the moment the indicators correspond to the norm appear, at intervals determined by the program, the system pulsates the opening and closing of the solenoid valve SV6 in order to wash the membrane of the bacterial filter BF1. After a certain time, the elements are switched off in reverse order.

To fill from the ready state, the “READY” banner lights up on the display unit.

Analysis of purified water in manual mode is carried out by the operator by pressing a button located on the upper surface of the dispenser. This function is available when the presence of water in the storage tank is above a critical level and the quality is determined by the characteristics of the system. The process is similar to starting the system in ready mode. When a command is received through the channel, a stable signal turns on the system at appropriate intervals and supplies power to SV10, then the state of LPS2 is monitored and UF1 is turned on, TMP3 is monitored and at the same time the temperature stabilization device Cool is turned on, then CS2 is monitored and from the moment the indicators of the norm, permission is received to fill and open valve SV 5 and close SV10, while monitoring is carried out using the FM1 sensor. The filling cycle will be performed with the BT2 button pressed until there is no water presence signal at the level of the LS4 sensor. Upon completion of filling, the elements are switched off sequentially. At the same time, the measurement results of CS2 and FM1, as well as the setting values, are printed out on paper by the built-in printer.

After activating the BT2 button, CS2 is monitored and from the moment the norm indicators appear, permission is received to fill and open valve SV5. Upon completion of filling, the elements are switched off sequentially, and at the same time, the measurement results of CS2 and FM1, as well as the setting values, are printed by the built-in printer on paper.

The process of filling the storage tank T1 is determined by the state of the level sensors LS1 and LS2 in the storage tank T1. If there is no water at the specified levels, the filling process starts.

Washing is carried out when installing new filters, as well as at specified intervals during operation of the device to eliminate the effect of water stagnation.

The direction of water for washing cartridges is carried out in service mode, the frequency is determined by the system. After flushing, the installation performs a self-test and the results are entered into a database in the controller’s memory and output to a data block for logging the state of the installation on an external information collection server (logging system).

The direction of water for flushing cartridges C1, C2, M1, BF1 and UF1 is carried out in service mode, the frequency is determined by the system. After flushing, the installation performs a self-test and the results are entered into a database in the controller’s memory and displayed in the logging system.

Service function Cartridge replacement C1, C2, M1, BF1 and UF1 is carried out in service mode. It is initiated using an electronic key included in the kit with replaceable elements. Occurs in the mode of communication between the installation and the user. The display unit displays text messages that define user actions, monitors execution and results are entered into a database in the controller’s memory and a logging system.

Controlling function of the CS1 indicator readings. Displayed in the Range 1.0-20.0 µS/cm. It is a service function and a determining value in the operation of the installation, has temperature compensation, is displayed in a database in the controller memory and a logging system
