The use of low pressure in the secondary pipe, and high mainly allows the purification of water in two stages: - first stage - with the passage of debris and algae through additional pipeline bubble veil of low pressure pulls up weeds inclusions from the bottom in the overlying water layers due to the buildup (encapsulating) of micro air bubbles on the surface of the raised body (flotation); - the second stage - intensive bombing raised from Nam the flow of the air-bubble curtains in the outlet channel.

All this allows to increase the degree of purification of water, as well as the efficiency of the device as a whole.

Device point, associated with the lateral channel, allows the complete process of cleaning water from the water source from debris and algae and to exclude further get into the areas below the intake. In addition, collect weed inclusion in the waste bin, as they accumulate, removed existing mechanical means and stored with the subsequent disposal of that is very important in the environmental aspect.

Device for automation of water treatment from debris and algae on the water intake pumping station works as follows. When the diversions (pumping and irrigation pumping station) in the reversible tank 13 is always maintained at a pressure in certain installation is from the top of the installation limit, in the result, the pressure sensor 14 mounted in the tank 13, and outputs a signal to stop the compressor 1, which leads to the cessation of growth pressure in the tank 13. As air flow from reversing tank 13 is the pressure drop to the lower limit that is causing generate a signal of the pressure sensor 14 at the start of the compressor 1. Thus, the stop-start mode of operation of the compressor 1 through the pressure sensor 14 provides for the operation of the device the pressure in the reversible tank 13 in the installation (specified) limits.

Air from reversible tank 13 through the open actuators 21 and 22, located at the beginning of perforated piping enters the links 10 of perforated pipes 2 and 3, causing them to fill.
