Noggerath® Vertical Sieve Screen NSI-V provides a solution to facilitate lifting, washing, dewatering, compaction of solids and improving the performance and reliability of drainage systems and is designed to be installed into sumps, manhole chambers, underground chambers, pumping stations.

During operation, solids in the incoming flow will progressively collect onto the screen. At a present inlet water level, the spiral will be activated and convey the solids up to the pressing zone, brushes fixed to the periphery at the lower section of the spiral will clean the screen mesh. The solids or screenings are compacted and dewatered and depending upon the solid properties, a volume reduction of around 40 percent dry solids or greater can be achieved prior to discharging the screenings into a bin.
