Grid efficiency is very high. Perforated pore diameter is usually between 6 to 10 mm. It is for ideal remove of solids which is diameter greater 10 mm. All equipment that may require intervention is easy to reach above the water level. Due to its compact design , space requirements are less. Solid materials kept on the screen surface are transported to the top of the system.After perforated pallets have emptied their waste, washing is done in the opposite direction of movement and thus they are constantly cleaned.At the same time, cleaning efficiency can be increased by integrating a clean water spray system on the surface of perforated pallets according to the operating needs.
