Get high-performance process and wastewater treatment in a single self-contained unit.
Providing a large area for filtration in a compact process vessel, the DynaDisc® delivers high-volume, low-headloss disc filtration for tertiary wastewater and industrial process water applications.
The DynaDisc® filter provides a large area for filtration in a compact process vessel. The discs are made up of a number of cassette pieces, joined together around a central drum, with a durable filter cloth bonded to the cassette to provide the filtration. The filter water is then used as the supply of washwater to clean the filter cloth when the headloss through the filter reaches a pre-set level.
Primarily designed for TSS and BOD removal, for which it delivers removals down to 10 mg/l for each, the DynaDisc® can also provide removals of effluent phosphorus down to 1 mg/l in its standard configuration and 0.25 mg/l with the addition of metal salts.

Water to be filtered is guided into the rotor drum and flows by gravity into the filter discs, through openings in the drum, and passes through the filter cloth. Suspended solids are separated and accumulate on the inside of the filter cloth.
When the water level inside the filter increases to a pre-set point, the filter starts rotating and the backwashing of the filter cloth is initiated. The high pressure backwash spray removes the accumulated suspended solids into the reject flume inside the central drum. The suspended solids are then discharged via the reject pipe.
65% of the disc area is submerged in operation, providing a high area through which the flow can pass.
