Description

KeenSen EP-8040FR is a high-performance, low-fouling reverse osmosis membrane element, offering excellent salt rejection, low pressure drop, and superior stability. It incorporates a new 34-LD feed-spacer design and advanced manufacturing technology. This membrane is ideal for wastewater treatment and water reuse applications in industries such as power generation, steel, electroplating，petrochemical, coal chemical, textiles, paper- making, and landfill leachate, where salt concentrations are below 10,000 mg/L. Compared to conventional low-fouling membranes, the EP-8040FR features a 30% lower pressure drop, enhancing its fouling resistant resistance, reducing the frequency of chemical cleanings, and significantly extending membrane life.

EP-8040FR

EP-8040FR is a high salt rejection, low pressure drop, and high stability anti-pollution reverse osmosis membrane element using a new type of 34-LD grid and production technology. It is suitable for power, steel, electroplating, petrochemical, coal chemical, dyeing, papermaking, and leachate wastewater treatment and reclaimed water reuse projects with salt concentration within 10000mg/L. The pressure drop of EP-8040FR is 30% lower than that of conventional anti-pollution membranes, further improving the anti-pollution ability of the membrane element, reducing the chemical cleaning cycle, and extending the service life of the membrane element.
