Water Treatment Plant

The proposed utility model relates to the field of water treatment and can be used to purify drinking water, as well as water for industrial needs.

A device for water purification is known, including a centrifugal pump with inlet and outlet pipes, an ejector tube mounted asymmetrically with an inlet pipe and a suction pipe and equipped with an air flow meter and a control valve, while the pump inlet pipe is connected to a suction pipe immersed in a container with purified water . (RU 2080300, CO2F 1 / 34.1997)

A disadvantage of the known device is the low degree of purification from suspended solids. In addition, the disadvantages of the known device include a limited amount of air supplied to the purified water.

A known station for the purification of biologically treated waters, including a microfilter, booster pump, ejector, bactericidal unit, saturator and control unit. (RU 2161138, CO2F 9/08, 2000)

The known installation is quite complicated.

The closest in technical essence and the achieved result is the installation for water purification from iron and dissolved gases COi and H2S, which contains a mixer, contact reservoir, pump, lighting filters, dispersant, ejector, and a confuser is installed in the upper part of the mixer to form a vacuum zone , and the amount of feed

the air ejector is regulated by a needle valve (RU 2119892, CO2F 1/64, 1998).

The disadvantage of the above device is its low efficiency due to the design flaws of the used ejector and confuser.

The objective of this utility model is to develop an installation that effectively purifies water from iron, manganese, and dissolved gases.

The problem is solved by the described installation for water purification, containing inlet, connecting and outlet pipelines, a pump, an ejector, a storage tank equipped with a level gauge connected to a valve in the inlet pipe, a filter, and the storage tank

installed between the ejector and the filter, the outlet pipe is equipped

sequentially installed pressure control device

and a hydraulic accumulator, while the pump is located between

capacity and filter.

In addition, the proposed installation contains valves, valves, manometers; the ejector contained in it is a two-phase gas-liquid, and the level gauge of the storage capacity is connected to a normally closed valve by a solenoid. As a pressure control device, a flow sensor or pressure switch is installed.

The principle of operation of the installation.

In FIG. 1 shows a diagram of the proposed installation.

The water to be purified from the source under pressure enters through a ball valve 5, a solenoid valve 4 and a check valve 6 to a two-phase gas-liquid ejector 3.

Water under pressure, which is recorded by the pressure gauge 2, is treated with air oxygen in the ejector 3, and then enters the storage tank 1. At the same time, due to jumps in the seals located in the mixing chamber and the expanding diffuser of the ejector, which translate

a supersonic flow of a two-phase mixture in a subsonic one, crushing of water to submicron sizes occurs, and a sharp decrease in the oxidation time of ferrous iron.

At the same time, hydrogen sulfide and carbon dioxide are removed by replacing them under reduced pressure created in the receiving chamber of the ejector and along the length of the ejector mixing chamber. In the storage tank 1, the final and complete oxidation of iron occurs, and its transfer to the trivalent state, while part of the agglomerated particles is deposited by gravity to the bottom of the tank 1. The level of treated water in the tank 1 is automatically supported by a float level gauge 8:

- when the lower water level in the tank is reached, the solenoid valve 4 opens and the tank is filled with the simultaneous treatment of water with atmospheric oxygen,

- when the upper water level is reached, the valve turns off and the water supply to the treatment is cut off. The treated water by the pump 10 is then sent to the fine filter 14, in which there is a complete deposition of solid particles and suspensions.

Part of the filtered water through the flow sensor 11 enters the accumulator 12 and then to the consumer. When the water is disassembled and the pressure in the accumulator drops below 1.5 atm, the pump 10 is automatically turned on, and after filling the accumulator 12 and stopping the water analysis, the flow sensor 11 is activated and the pump 10 is turned off. In the absence of water in the storage tank, the flow sensor 11 provides dry running protection of the pump.

When sediment is accumulated in tank 1 once every 6 months, the sediment is drained through tee 9 into the sewer and the storage tank is flushed, and the filter is replaced at the same time.

the proposed installation allows you to:

-produce high-quality water purification from dissolved iron to a level of 0.3 mg / l;

-increase the oxidation rate of two valence iron a thousand times;

- Completely remove hydrogen sulfide and aggressive carbon dioxide.
