Sand washing plant HIDROSAND

Meant to eliminate grits in the inert residual spillway or as a pre requirement for the recycling. Grit treatment systems requirements: The regulation: For municipal residues: Class 1 spillway: matter content organic<3% Class 2 spillway: matter content organic<5% For the recycling and elimination of residues Priority recycling in towards the elimination New grit treatment technologies are required to lower the escalating costs of elimination The problem Grit incoming from the WWTP: The grit form the waste water treatment plants , which has been separated by the means of conventional aerated grit removal systems or grit classifying systems, do not comply with the new regulations due to their high organic content. The reduction of the organic content in the grit can be achieved by means of an innovative design: the grit washing HIDROSAND ®plant that combines the functions of a conventional grit classifier classifying-transport with an additional grit washing system. In such way, it is possible to economically reduce the content of organic matter in the sand allowing: -its elimination in the spillways of inert residues or municipal. -its recycling
