Microscreen Filter Microscreen Filtration with unrivalled Reliability and Durability. Product Profile 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. 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. • Filter cloth fastened directly to the cassette body - keeps the seal length to a minimum. • Tertiary treatment of wastewater. • Strong cassette body – allows high tension on the filter cloth, prolonging its service life. • Pulp and paper industry. • Purification of process water. • 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. • Integrated level tank – provides a long level weir for the filtrate which reduces fluctuations at different water flows. • 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. • The chemical solution for cleaning the filter cloth is collected in the level tank, thus reducing acid corrosion of the concrete.
