MI-range screens are integrated machines consisting of a screen, a shaft-less spiral and a press unit. During operation, solids within the incoming flow will progressively collect onto the screen mesh and cause it to gradually blind. The upstream water level will rise 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.
SP-Range screw screens are designed to handle higher solids content or concentrations including irregular size matter or materials with negligible risk of jamming. Screens are self-cleaning and available in various sizes
The TOP systems integrate screening and grit separation with the option of fat, oil and grease (FOG) removal, all within a single packaged unit.
Wastewater enters the screen section where the gross solids are removed from the flow, washed , compacted and dewatered. Depending upon the solid properties, a volume reduction of around 40% DS or greater with organic washing efficiencies >90% can be achieved prior to discharging the screenings into a container. The screened effluent then discharges to a hopper section where grit and sand settlement is induced. The grit is conveyed to a grit classifier and can be further washed prior to dewatering and disposal into a container.
