DynaDisc®

Microscreen Filter

Microscreen Filtration with unrivalled Reliability and Durability.
Product Profile

Advantages

The DynaDisc® is a microscreen consisting of multiple filter discs.
The reliability of the DynaDisc® seals and durability of the filter
fabrics allows the system to be used in a wide range of applications.

•

Applications

Fewer parts – the DynaDisc® has 8 or 10 cassettes per
disc, which is several times fewer than in disc filters from
other manufacturers. This means faster replacement and
less weight.

•t Filter cloth fastened directly to the cassette body - keeps the
seal length to a minimum.

•t Tertiary treatment of wastewater.

•t Strong cassette body – allows high tension on the filter cloth,
prolonging its service life.

•t Pulp and paper industry.
•t Purification of process water.
•t Recirculation of cooling water in the steel industry.

How it Works
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.

•t Integrated level tank – provides a long level weir for the filtrate
which reduces fluctuations at different water flows.
•t The filtrate in the level tank is used for backwash – less risk
for biological flocks compared to when the backwash water is
taken from a much larger concrete tank.
•t The chemical solution for cleaning the filter cloth is collected
in the level tank, thus reducing acid corrosion of the concrete.
