Perforated Grids are grids that can operate in an infinite loop thanks to the chain gear system. Thanks to its compact design, the space requirement is less. The perforated pore diameter is usually between 6-10 mm. It is ideal for the removal of solids over 10 mm. It is produced for use in deep channels with high water level. All equipment that may require intervention is easily accessible above the water level. Solid materials held on the grid surface are transported to the top of the system. After the perforated pallets empty their waste, they are cleaned continuously by washing in the opposite direction of movement. At the same time, cleaning efficiency can be increased by integrating a clean water spray system on the surface of the perforated pallets according to the operational needs.
