• Different from the traditional spiral wound reverse osmosis membrane, the water flow channel of the open channel reverse osmosis membrane is open, and will not form a tortuous flow channel like the spiral membrane, which greatly reduces the concentration polarization effect and the risk of accumulation of pollutants on the membrane surface;

• The open channel design is easier to be fully contacted by the cleaning liquid, so that the inside of the membrane element can be more effectively cleaned, improving the cleaning efficiency;

• The open channel design and good water flow conditions can provide higher water flux, thereby improving the processing capacity of the entire system.

---Description

• The flow rate of a single membrane element may be different, but the variation range will not exceed +15%;

• The stable desalination rate generally needs to be tested after 24-48 hours of continuous operation, depending on the inlet water quality and operating conditions.
