MEGA Electric Suction Filters


Automatic self cleaning suction or brush, specially designed for very high flows up to 14.000 m3/h (61.600 gpm), combines  the advantages of high quality filtration from different water sources (sewage, reservoirs, rivers, lakes, etc), with self-cleaning features, offering a continuous water supply.

Water enters the filter through the “inlet” and passes through the coarse screen that functions as a “first stop” for rough particles. Water then reaches the fine screen which further purifies the flow by separating smaller particles from the water. As more water flows through, impurities build up on the fine . As impurities on the screen accumulate, a pressure imbalance is built up between the internal section of the fine screen and the external section.

Cleaning process – “Flushing”

When the difference in pressure (DP) reaches the preset value on the differential pressure indicator, a serious of events happen while the water continues to flow to the system units: the flushing valve opens, and water flows outside. Pressure in the hydraulic 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 the moves it along its axis. The combination of the linear movement and the rotation significantly clean the whole internal screen surface.

The flushing cycle continues as long as the pressure difference between the inlet and the outlet remains the same and according to the signals form the controller. If the pressure difference remains unchanged for a fixed reset time, the emergency flushing valve opens along with the normal flushing valve. The flushing cycle continues for an additional fixed time that was preset on the controller. Both the flushing valves close when the pressure difference on the pressostat drops. The operation of the electric motor is stopped after the collector axis reaches the internal or external limit switches. The filter is now ready for the next cycle, with clean and filtered water flowing throughout the “Outlet”.

Each Mega filter contains 2 or more screens in one filter body.

The flushing process can be programmed (on request) to work either each screen separately or in pairs.

Filtration degree: from 20-3000 micron
