The Yuasa backwash-type flat membrane system is a device that forms a sludge cake layer on the surface of the flat membrane through suction filtration and detaches and collects the cake through backwashing. It can be used for the recovery of silicon polishing powder, rare metals, and other inorganic SS. It enables sludge dewatering with a moisture content of 50-80 wt% without the use of coagulants, and by employing a membrane with a nominal pore size of 0.25 μm, it achieves SS levels in the filtrate of less than 1 mg/L! ★ Free evaluation test campaign currently underway ★ 【Features】 ■ Enables sludge dewatering with a moisture content of 50-80 wt% without the use of coagulants ■ Achieves SS levels in the filtrate of less than 1 mg/L due to the use of a membrane with a nominal pore size of 0.25 μm *For more details, please refer to the PDF document or feel free to contact us.

The backwash-type Yuasa is a backwash immersion membrane separation device that can efficiently perform filtration, sludge recovery, and sludge concentration. It filters the concentrated liquid in the immersion tank by suction, causing sludge to adhere to the membrane surface. After a certain period, the membrane module rises and backwashes to detach the sludge from the membrane surface. It enables sludge volume reduction and the recovery of chemical-free sludge.
