Road Sweeping, Gully Waste and Sand from Sewage Treatment Plants

DIEMME SOIL WASHING has developed, with proprietary technologies, a process of treatment and recovery of waste from street sweeping, gully waste and sands from sewage treatment plants (EWC 200303, 200304, 200306) which allows to greatly reduce the environmental impact generated by these types of waste by recovering most of the inert fraction minimizing what is left over for disposal.
The treatment of these wastes differs from the Soil Washing used on contaminated soils and sediments for the peculiarities typical of the input matrix, for the variability and seasonality of the waste and for the presence of contaminants spread over the whole particle size spectrum.
The treatment and recirculation of process water allows to minimize the use of fresh clean water while reducing the operational costs of the plant.
