➤➤➤ FunctionThe WAP/SL operates in a batch mode. Screenings eitherdrop into the launder tank directly from a screen orconveyor, or they are flushed into the tank through alaunder channel. After a batch of screenings has beenfed, the tank is filled up with wash water and agitated foran adjustable period by means of an impeller. The fecalmatter is loosened and removed from the screenings byhigh turbulence and shear.After the washing cycle has been finished, an automaticvalve opens and the wash water drains throughperforations in the trough. It returns, together with thefecal matter, to the wastewater flow. A screw in thetrough conveys the screenings towards the mouth of atube whereby they are, as an additional option, rinsedwith spray water. The screw pushes the screeningsthrough the pressure zone where they are compressed,dewatered and compacted before they are finallydischarged through the discharge pipe into a dumpsteror bagger.➤➤➤ Feeding through alaunder channelThe screenings drop from the screen or conveyor into alaunder channel. Screened wastewater or process waterflushes the screenings through the channel into thelaunder tank of the washpress.
