AI Technical Summary
Existing flat-plate filter membranes have poor operating conditions for replacement in water treatment and are prone to clogging, especially in reverse osmosis membrane modules where the gaps between the membrane sheets are narrow and easily blocked.
Design a spoke-type flat sheet membrane filter tank, in which the membrane sheets are vertically arranged outside the tank body and spread out radially. Side partitions are set between the membrane sheets to form a spacious gap and reduce the risk of clogging.
This allows for membrane replacement outside the water tank, reducing the hazards of the operating environment and improving filtration efficiency by minimizing the possibility of clogging through ample clearance.
