First, the function and use:
         Model ZPG-LZ Series Automatic backwash sewage filter to apply in industrial wastewater treatment processes, iron and steel plant slag water, power plant process and cooling water, papermaking processes and water, chemical production processes
And irrigation systems and other occasions, for the filtered water ***0 to **0 microns particle size of the hard particles, to ensure safe and reliable operation of the system.

Second, the structure and working principle:
       Model ZPG-LZ series of automatic sewage filter backwash to the use of high strength stainless steel mesh, and handling capacity, long service life, cleaning efficiency. This machine adopts intelligent pressure control, timing control automatically recoil washed the filter. When the filter pressure drop of the set value or the timer reaches the set time, the electric control box signal to drive the valve rotation, while the drain valve open. At this time water was forced from the entrance hole of the filter tube into the cartridge outside shell sandwich
Reverse flushing filter lateral adhesion of the impurities on the mesh, to clean the purpose of the filter, the filter pressure drop back to normal or timer setting time after the end of
The motor stops rotating, electric drain valve is closed. Throughout the process, the liquid flow, to achieve a continuous, automated production.
