LP8040-400
Brackish Water Reverse Osmosis Membrane
Reduces operating costs and pressure requirements for pump systems;
Maintains long-term stable high water volume under low operating pressure, improving the treatment efficiency of the entire water treatment system;
Improves membrane layer structure and increases specific surface area, which can reduce energy consumption under the same water production demand, meeting the requirements of energy conservation and environmental protection;
The membrane surface has been specially treated to enhance the ability to resist biological and chemical pollution and extend the service life of the membrane.

---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.
