The Kusters Water wash compactor is synonymous with hygienic and efficient handling of screenings. Screening disposal is a cost factor for every installation; wet screenings are heavy and increase disposal costs. The fecal matter in the water must also be delivered to the subsequent sewage purification process. The Kusters Water wash compactor reduces the weight and volume of the screenings while washing out more than 95% of fecal matter. Kusters Water wash compactors provide high performance combined with low operating costs to provide an excellent cost/performance ratio.
The screenings are discharged directly from a screening unit, conveyor, or flume to the press 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. 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 where 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.
