The Kusters Water grit washer was developed with two aims in mind:

To achieve a very high separation performance of the finest grit particles.

To achieve grit with < 3% total volatile solids.

The Kusters Water grit washer consists of two basic items – a rotating perforated screening drum and a grit separator/washer unit, however, if the plant has fine screens (<10mm perforated screens), the screening drum can be eliminated. Special emphasis has been placed on maintaining low water consumption while achieving high grit capture rates and low volatile solids concentrations. The Kusters Water grit washer accomplishes these while providing high performance coupled with low operating costs.

Kusters Water has been directly involved in the design, manufacture, supply, start up and testing of the XGT vortex grit removal technology since 1984. Based on experience with many installations, we have introduced a number of significant improvements to the system. These include the selfpriming grit pump and vortex grit classifier. The XGT vortex grit system is designed to efficiently remove both fecal and vegetable matter (corn, rice, beans, peas etc.) from the grit in the grit chamber resulting in cleaner grit with considerably lower organic content.

The Kusters Water Perforated Plate Filter Screen was developed to solve modern day screening problems which occur in wastewater pretreatment. The Kusters Water Perforated Plate Filter Screen eliminates operational disruptions caused by fibrous and other inorganic material. Depending on the perforated panel, the screened material is greater compared to a bar screen. The quality of the screened effluent is noticeably improved, which in turn improves performance and protects downstream equipment.

The Kusters Water ProTechtor® Centerflow Band Screen, with its vertical orientation, is an excellent alternative to applications with limited footprint and headspace. Influent flow enters the screen in the middle of the screen frame, and is positively screened as the flow transitions from the inside and passes through the traveling perforated filter belt through the sides and bottom. Optimally spaced lifting tines are attached to filter panels to capture and elevate larger items to the internal discharge point. Screenings are washed off via spray headers and/or a combined motorized brush assembly, and are discharged to an internal flume or screenings washer compactor, which transports the screenings outside of the screen frame. The quality of the screened effluent is drastically improved which in turn improves performance and better protects downstream equipment.

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 Kusters Water Multi-Rake Bar Screen was developed to solve the most demanding problems associated with wastewater pre-treatment. Kusters Water improved the basic design of conventional bar screens to offer a unique product to meet the ever increasing process needs of end users. The Kusters Water Multi-Rake Bar Screen combines fine or coarse screening with high solids capture rates, robust construction, long life, and low O&M costs all in one screen. This combination ensures operation when you need it most.
