DETAIL DESCRIPTION

Automatic Backwash Filter for municipality water supply system

A200 series have two-stage filtration (coarse screen and fine screen). Suction nozzle type cleaning method, horizontal installation.

Operation

This automatic electric filter combines the advantages of high quality filtration from different water sources (sewage, reservoirs, rivers, lakes, etc.) with self-cleaning feature, offering the customer a continuous water supply.

The filters are designed for use in wide range of Industrial, municipal and irrigation applications.
Cleaning of the screen is performed once the pressure loss (ΔP) across the filter has reached the preset value [up to 0.5 bar (7psi)].

The filter is equipped with a coarse screen that protects the finer screen from stones and larger particles.

The flushing valve opens and pressure in the flushing chamber and the dirt collector is significantly lowered resulting in a suction process via the suction nozzles to the dirt collector and from there through the flushing valve outside. The electric motor simultaneously rotates the dirt collector and moves it along its axis. The combination of the vertical movement and rotation guarantees that the suction nozzles will cover the entire internal screen surface, efficiently cleaning the screen. The whole process takes 12-18 seconds.
During the whole process water supply is uninterrupted.
