Landfill construction - Import export

Application Sewer grit from sewerage units has a high organic load and, therefore, its disposal goes along with high costs. Here, a treatment and disposal in compliance with legal provisions is required. Therefore, it seems to be imperative to reduce or treat sewer grit and street rubble by washing so that this material can be recycled or disposed on a construction waste landfill. A reduction of screenings and a low-cost waste disposal can decrease the costs to a high degree. Many years of experience with the treatment of these materials guarantee for a supply of high quality standard units resp. custom-made units tailored to your specific application.

Application Standard grit trap contents have an organic proportion of 50 to 80 %. Conventional sand washers are able to dewater the grit trap settlings only partially. But, the high organic content and the lack of dry substance bring on unpleasant odour, high weight and, as a consequence, high costs for disposal. With the PWL Sand Washer the organics in the grit trap can be nearly completely washed out. This results into a reduction of mass of up to 80 % and might cause cost savings of up to 90 % when being disposed on a construction waste landfill. This procedure can be applied in industry, as well, to separate valuable materials from waste. Due to the separate discharge of the various fractions they can be further treated, recycled or disposed. Thus, valuable materials can be returned to the production process and waste material be disposed at low costs and correctly sorted. Function The PWL Sand Washer is fed with a sand-water-mixture. The settled sediment mixture is conveyed...
