• Nanofiltration membrane has excellent selective separation performance, which is achieved by combining charge effect and screening effect, and is highly selective for specific ions and molecules;

• Without chlorination or any oxidation treatment, the membrane element is guaranteed to have long-term stable and efficient performance;

• Good chemical cleaning recovery performance, reducing the cleaning frequency, thereby extending the service life of the membrane element and reducing maintenance costs.

---Description

• The flow rate of a single membrane element may be different, but the range of variation 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.
