The treatment plant UNILOS - ACTIVE is carried out as follows.

Wastewater through the inlet pipe I enters the averaging tank 01 with a grate 01.1, on which large waste remains. The grate is removable, with the possibility of removing accumulated large waste. The mode of wastewater inflow can be both gravity and pressure. Under the gravity flow regime of wastewater intake, it is envisaged to modify the averaging capacity for various depths of inlet pipes (0.6, 0.9, and 1.2 meters). The volume of the averaging capacity is calculated for the accumulation of wastewater during salvo discharges and with the possibility of water analysis during the absence of wastewater inflow. The residence time of wastewater in the tank at a nominal capacity of at least 8 hours.

Wastewater aeration in the averaging tank occurs in the following cases:

- modification without denitrification during removal of excess sludge from the secondary sump 03.

- modification with denitrification during aeration in aeration tank 02.

Pump 01.2 is fully automated.

The float level sensor 01.4 detects the lower operating level and switches the pump on and off depending on the liquid level in the tank 01. The float level sensor 01.5 determines the emergency level and turns on the alarm.

Pump 01.2 operates cyclically with the specified time intervals for operation and downtime. Information is stored in the memory of the control controller of the control unit 09.

From the averaging tank 01, the effluent enters the aeration tank 02 through the pressure pipe II. The capacity of the aeration tank 02 is designed for the hydraulic residence time of wastewater at a nominal capacity of at least 6 hours. In aeration tank 02, organic pollution is oxidized, suspended particles and small floating particles are removed from wastewater due to the presence of activated sludge and biofilm. Mixing of the sludge mixture is carried out by aeration through aeration elements 02.4 connected to the air duct XV.02.4. The operating mode of the aeration elements is different depending on the modification of the aeration tank 02:

- modification without denitrification - aeration mode is constant;

- modification with nitrification - aeration mode is cyclic with specified time intervals for operation and downtime. Information about the digital values of the intervals is stored in the memory of the control controller of the control unit 09.

A feature of aeration tank 02 is the presence of a floating load 02.1, which increases the oxidative power of the aeration tank and provides a nitrification process in a limited volume and under adverse conditions, such as low temperature. Returned activated sludge enters the aeration tank 02 through the pressure pipe X. From the aeration tank, the sludge mixture by airlift 02.2 enters the secondary sump 03 through the pressure pipe III. A gravity pipe III * is provided in the aeration tank for emergency overflow of the sludge mixture into the secondary sump 03.

In the secondary sump 03, the sludge mixture is separated, while activated sludge is compacted and deposited at the bottom in the pyramidal part of the sump, and the purified water is discharged through the gravity pipe of biologically treated water IV to the post-treatment filter 06. Airlift 03.2 of pipe X works alternately with the specified control controller 09 time intervals. Airlift 03.2 pumps the sludge into the aeration tank 02. The device for removing floating substances 03.5 is connected to the air duct XV.03.5, which is connected to the solenoid valve 09.3.

Airlift 03.3 of the XI pipeline operates alternately with the time intervals specified by the control controller 09. Airlift 03.3 pumps the sludge into the sludge stabilizer 04.

Airlift 03.2 and 03.3 are connected to the air ducts XV.03.2 and XV.03.3, respectively, which in turn are connected to the solenoid valve 09.3.

The device for blowing thin-layer modules 03.4 is designed to clean thin-layer modules from sludge particles deposited on their surface. Device 03.4 is connected to the air duct XV.03.4 and works in conjunction with the airlift 03.3 in accordance with the specified interval.

Excess sludge from the secondary sump 03 through the pressure pipe XI enters the sludge stabilizer 04. The volume of the stabilizer 04 is calculated taking into account the presence of sludge in it for at least 5 days.

The sludge enters the flow guide 04.1, sinks to the bottom of the stabilizer 04 and is aerated with the help of compressed air supplied through the air duct XV.04.2 through the aeration elements 04.2.

When the sludge stabilizer overflows, the fermented sludge flows through the gravity pipe XII into the sludge dehydrator 05.

If the complex is not equipped with sludge dehydrator 05, then the fermented sludge flows into the storage tank.

In the sludge dehydrator 05 sludge enters the filter bag 05.2. The filtrate enters the tank of sludge dehydrator 05 and is pumped out by pump 05.1 through pressure pipe IX to the averaging tank with grate 01. The pump is switched on and off by a signal from the float level sensor 05.4. In the embodiment in which the sludge dehydrator is installed in the averaging tank, the pump is not used, the filtrate enters directly into the averaging tank with a grill 01.

The operation of the post-treatment filter 06 is fully automated and is controlled by the control unit 09, as well as by float level sensors 06.5, 06.6 and 06.7.

The filter operates in the filtration mode as follows: biologically purified water from the secondary sump 03 enters through a gravity line IV into the post-treatment filter 06. In gravity flow, water is filtered through the loading layers 06.1. Water aeration is carried out by means of air supply from compressor 09.1 through air duct XV.06.4 to aeration elements 06.4. Pump 06.2 is programmed with a timer that turns on the pump for 1 minute every hour. When the float level sensor 06.7 is triggered, the pump turns on and lowers the level to normal. When the level sensor 06.6 is triggered, it turns off the pump 06.2.

The filter works in the washing rinse mode as follows: the solenoid valve 09.4 switches the air supply to the air duct XV.06.8, to which hole pipes 06.8 are connected. Coming out of them, the air sparges the load. At the same time, the pump 06.3 is turned on and pumps water from the after-treatment filter tank to the averaging tank with the grill 01 through the pressure pipe XIII. The 06.3 pump is switched off when the float level sensor 06.5 is triggered. Switching the operation of the filter between filtering and flushing is carried out through the control unit 09, with predetermined time intervals between flushing.

The purified water through the pressure pipe V enters the water disinfection unit 07. The installation provides for bypass water drainage, bypassing the installation 07.1 to protect the equipment during the period when the installation goes into operation. Disinfected water through gravity pipe VI enters the tank of purified water with pump 08. When the float level sensor 08.2 is triggered, pump 08.1 is turned on and pumps water to the discharge point.
