Perforated screens are a fine screen model designed to keep very small diameters of suspended solids in wastewater with high efficiency. It is one of the most helpful equipment in reducing maintenance and repair costs in treatment plants by providing the capture of wastes that cannot be kept in coarse and fine screens in pre-treatment systems. The wastes clinging to the grid surface consisting of chain-driven perforated sheet slices are swept into the garbage container with the help of a rotating brush and backwash is applied to the perforated grid slices against clogging in the perforated holes. It can be operated with level adjustment or time adjustment.
