One of the most important factors of long service life of water management installations is their protection against trash and debris that may cause their clogging, fouling or damage to important equipment parts. Manually raked screens are suitable for conventional treatment plants, vegetation (root) units, pumping stations and other sections of sewer systems as their pre-treatment stages.
Manually raked screens consist of an inclined screen grill fixed in a plastic box, which is subsequently installed to an open rectangular-section sewer. The rakings trapped on the grill are pushed up by a manually-operated rake hook to a crosswise shallow though with a perforated bottom.
Note: The thrash screen can be also custom-made according to individual requirements and adequate dimensions.
