Noggerath®
Circular Grit Washer
GWC
More environmentally conscious disposal and significant reduction of costs by lowering the amount of organic matter in the washed grit.
Aqseptence Group offers you the largest range of grit washing systems worldwide and the most comprehensive variety of constructional and process technological designs. As such we are able to optimally tailor a grit treatment process to meet your specific requirements.
The Noggerath® Grit Washer GWC provides washed wastewater grit with less than 3% organic material. This reduction in the amount of residue means considerable savings on transport costs can be achieved. In addition, the reintroduction of the washed organic matter into the wastewater stream leads to an increase in nutrient availability. This means that the addition of external carbon might not be necessary for downstream denitrification processes and may also result in an overall improvement in gas production in any sludge digestion.
