The Hycor® Helisieve® M combines fine screening, conveying and dewatering to create a highly economical self-contained wastewater treatment system. It produces screenings dry enough to take to a landfill without the need of an additional dewatering press. Screen openings are available in the standard 1/4” perforations or optional 1/8”. The heart of the system is a shaftless spiral with a brush in the screen basket area to keep the screen clean.
Operation of the spiral is based on level control upstream of the screen basket. Screened solids are conveyed out of the channel, dewatered and discharged into a dumpster or conveyor. New to the system is a patent pending, adjustable spool compaction tube which can be set to achieve drier solids or set in EZ-Wipe™ mode to enlarge the solids drop zone and reduce potential clogging due to wipes and rags.
Units are available in a tank when a channel is not available. A common in-tank option is also available to pre-treat septage (with special controls) prior to being accepted in a wastewater treatment plant.
