The DynaDisc is a cassette filter using 10 to 20 micron cloth media to filter out fine particles from wastewater.It is primarily used for TSS, BOD and TP removal. 

Influent flows into the drum and through the cloth media by gravity, where particles are captured. When the captured particles accumulate to a certain point, the water level in the drum rises and the filter starts rotating to backwash the filter cloth.

A high pressure backwash spray concentrates the particles washed off the media into a reject flume, where it exits the drum via a reject pipe. No separate washwater tanks are required and the filtration process operates continuously even during backwash, as the washwater is harvested from the clean side of the filter.
