SCREENINGS WASHER COMPACTOR

PRINCIPLE OF OPERATION

The screenings are discharged directly from a screening unit, conveyor, or flume to the compactor feed hopper. The screw then transports the screenings to the washing zone were service water is added and the organic matter is washed out. Fecal matter is loosened and washed off the screenings in the wash zone by a washboard/friction process. Hairs, fibers, etc. which could cause mechanical breakdowns and blockages in the downstream process are retained in the screenings. An optional agitator with soaking zone and modified control sequence can also be provided. The water and solubilized organics which are removed by this process are then returned to the wastewater channel via a collection pan. The screw then delivers the washed screenings to the press zone were they are dewatered, with the water also being delivered back to channel via the collection pan. The dewatered screenings are then discharged via a discharge pipe to a container, or conveyor. A shredding device or optional bagging unit are also available for installation on the end of the discharge pipe if desired.
