Reverse Osmosis

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.

Test conditions: 2,000ppm NaCl aqueous solution, Pressure 225psi (1.55MPa), Temperature 25℃, pH 7-8, Recovery rate 15%.

---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.

Customers' Recognition Of Us

Manager of Technical Department of Municipal Water Company

"When we renovated our municipal water plant, we compared several membrane products. The anti-pollution performance of Septane membrane was amazing! After 8 months of continuous operation, the flux decay was less than 5%, and the backwash cycle was extended by 3 times. The agent followed up the water quality monit...

Technical Director of Beverage Company

"The food factory production line has strict requirements on water quality. The nanofiltration membrane has not been blocked for half a year, and even the flavor of the concentrated juice is purer. The selection scheme provided by the agent accurately matches the production capacity. Now the treatment cost per ton...

Industrial Park Water Treatment Manager

"I have been using Sept's reverse osmosis membrane for almost a year, and the desalination rate has always remained above 99%. Even high-hardness groundwater can be directly reused after treatment. The after-sales team regularly visits to test the membrane performance. When the equipment broke down last time, they...
