HUBER Screenings Wash Press WAP/SL
The WAP® SL operates in a batch mode. Screenings either drop into the launder tank directly from a screen or conveyor, or they are flushed into the tank through a launder channel. After a batch of screenings has been fed, the tank is filled up with wash water and agitated for an adjustable period by means of an impeller.
The fecal matter is loosened and removed from the screenings by high turbulence and shear. After the washing cycle has been finished, an automatic valve opens and the wash water drains through perforations in the trough. It returns, together with the fecal matter, to the wastewater flow.
A screw in the trough conveys the screenings towards the mouth of a tube whereby they are, as an additional option, rinsed with spray water. The screw pushes the screenings through the pressure zone where they are compressed, dewatered and compacted before they are finally discharged through the discharge pipe into a dumpster or bagger.
