HOW IT WORKS

Filtered water from each single plate is collected inside the module housing and transported to the header set through 4 filtered water channels integrated in both module housing sides.

The filtration towers are fully submerged in a tank (filtration train) which contains the feed (raw) water. All towers are connected at the top with a common header pipe. The filtered water is transported through the header set of each tower to the top and from there through the common header pipe to the tank outside where a filtration pump is connected to transfer the clean water to the filtered water tank.

Reversed flow direction to filtration. A very small amount of filtered water is used to backwash the membrane. Within seconds, the formed cake layer comes off in flakes. Air-scouring can enhance the cake layer removal.

Filtered water from all 4 filtered water channels is transported to both module fronts and enters from there into each single plate.

A small portion of the produced filtered water is taken from the filtered water tank and is transferred by a backwash pump through the common header pipe into each filtration tower.

Complete cake layer is removed from the membrane surface after executed backwash. The membrane looks white without deposits on the surface.

It requires only a few seconds till the entire cake layer is removed. An air-scouring secures that the removed cake layer is well mixed while the filtration tank is drained.
