Description of the application of the proposed device for water purification: water enters the mechanical purification filter, purified from mechanical impurities and suspensions, water enters the buffer tank, equipped with a filter bed in the form of quartz sand with four-layer grain size, perforated plates, a central column, control sensors that automatically control the water level and the flushing water discharge pipe. The water passing through the buffer tank, where the pressure equalization process is maintained and the required volume of purified water is maintained, as well as the excess of purified water is recycled, enters the water mixer tank with air, additionally equipped with control sensors, process pumps that push the oncoming water flows through the nozzles , and pumping water, creating a vacuum, an ejector, with the help of which there is abundant saturation of the water to be treated with oxygen, as well as a flushing water drain pipe, with which Stem was backwashed with clean water 1 time per month. Partial disinfection of water takes place in a water-air mixing tank, and due to abundant oxygenation, oxidation and coagulation processes arise. From the tank-mixer of water with air, water is fed through a central column to a coagulator equipped with a central column and a flush water discharge pipe, where deaeration and return of an excess volume of return liquid to the buffer tank occurs, which contributes to the onset of oxidation processes and coagulation in the raw raw water. The coagulator contributes to the process of completing coagulation with the formation of flakes visible to the naked eye and separating them from water, which are discharged through the flushing water drain pipe once every 2-3 days. Water is supplied from the coagulator to a bulk filter, equipped with a filter bed in the form of quartz sand with four-layer granularity of the layers, perforated plates, a central column and a flush water discharge nozzle. Water is supplied with a direction from bottom to top, which helps to retain the flakes formed in the coagulator due to gravity and due to the solidification of particles in the gaps. The bulk filter is backwashed through the flushing water drain pipe with clean water once a month. From the bulk filter, water enters a filter catalytically active for manganese and iron, equipped with a bed of ion-exchange resin regenerated with saline, which helps to remove hardness salt and prevents the formation of water scale. If the manganese, phenol, and various resins are exceeded, the catalytically active filter for manganese and iron is filled with granular charcoal with retaining layers in the form of quartz sand. From the filter catalytically active to manganese and iron, water enters the clean water tank, additionally equipped with an ultraviolet disinfection unit that prevents the growth of bacteria, control sensors and a flow meter. From the reservoir of pure water, water flows to the consumer. By the differences in the amount of water supplied for treatment and the amount of clean water entering the tank per unit of time, the filtering state is monitored in the form of quartz sand with four-layer granularity of layers; upon reaching a critical drop in productivity, a signal is sent by automated control that requires flushing. Flushing the system is carried out by reverse water. System flushing frequency - 1 time per month.

When purifying river water, it is proposed to use a reagent, for example, aluminum sulfate or Aqua-Aurat-30, placed in an activation unit equipped with a flow meter.

The proposed water treatment system operates in non-pressure mode. Automated control is carried out using control sensors.

As an example, the data of the protocol of laboratory studies of water before and after using the inventive water treatment system (table) are given.

Thus, a water treatment system was created with high quality purified water, ease of maintenance and an extended service life.
