Screen Compactor
Johnson Screens’ screen compactor is a cost effective integrated machine consisting of a screen, a shaftless spiral and a press unit.
Solids from the incoming flow collect onto the screen mesh and cause it to gradually blind. The upstream water level rises and at a predetermined level, the spiral will be activated. Brushes fixed to the periphery at the lower section of the spiral will then clean the screen mesh and convey the solids up to the pressing zone.
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. Washing can also be incorporated in the screening, transport and/or compaction zones. Faecal matter washing efficiencies greater than 90 percent can be achieved.
Options include installation in a channel or delivered in a stainless steel tank. Other variants include the vertical screen and the minyscreen.
The SC range of screens is extremely cost effective – lower outlay and operational costs without any compromise to performance, reliability or asset life.
Flow Capacities
Up to 1080 m³/hr depending upon effluent and solids contained within the flow.
