DSS-V vertical screens are part of the DSS, Drycake Screw-Screen, series. DSS-V are integrated machines consisting of a screen, a spiral and a press unit. During operation, solids in the incoming flow will progressively collect onto the screen mesh. At a pre-set 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% DS or greater can be achieved prior to discharging the screenings into a skip or wheelie bin. Continuous bagging systems are also available to receive screenings and abate odour, the screenings can then be sealed without any personal contact.
