A high-flow disc tube membrane core
By using a multi-stage diversion and flow guiding unit and a star-shaped sealing ring, the disc tube membrane core solves the problems of flow channel blockage and high pressure loss in disc tube reverse osmosis modules for treating highly difficult wastewater. This achieves high flow rate and high recovery rate, and improves the membrane's antifouling ability and sealing performance.

AI Technical Summary
Existing disc tube reverse osmosis units suffer from problems such as flow channel blockage, large pressure loss, and poor flushing effect in the treatment of highly difficult wastewater. They are particularly unable to effectively treat high flow rates, resulting in limited water production capacity.
It adopts a multi-stage steering and guiding unit structure, including a combination of single-sided and double-sided channel guiding plates. The guiding plates are equipped with protrusions and fixed support points, positioning columns and arc grooves, and the sealing ring adopts a star-shaped structure to realize the flow path of sewage from side to side, and achieve multiple concentrations through multiple sets of membrane cores.
It achieves high-flow-rate influent, reduces concentration polarization, improves recovery rate, reduces the number of membrane columns, reduces floor space and cost, and enhances the membrane's antifouling ability and sealing performance.
