ESNA membrane is a product developed by Hyde energy company with new technology, which has excellent energy saving effect. This series of nanofiltration membrane is mainly used to soften, remove pesticides and bacteria. Under standard test conditions, the desalination rate range of ESNA series is about 91-99%(see technical sheet for specific test conditions of each model).

ESNA film can also remove iron and TOC, allowing the penetration of monovalent salts such as Na and Cl, thus making it suitable for municipal drinking water system applications. Using advanced membrane technology and unique characteristics of headenergy, ESNA membrane can help the system significantly reduce operating costs and energy consumption.

Esna1-lf-ld is a high desalination nanofiltration membrane, which is used to soften and remove pesticides, bacteria and viruses. Low operating pressure, good energy saving effect, reduce installation and operation cost.

Esna1-lf-ld membrane element adopts patented 34 mil water inlet screen to prevent colloid fouling and improve membrane cleaning effect.

Esna1-lf-ld can be cleaned less frequently, reduce maintenance cost, and maintain stable performance.

The hardness removal rate of ESNA1-LF-LD is high. Esna1-lf-ld is available in 4 "and 8" specifications.

* for a typical 500mg/L underground water source, the operating temperature is 25℃ and the water flux is 22LMH, it is estimated that the calcium ion removal rate is 96%.

* the performance parameters are obtained after the system runs steadily for 10 minutes. The actual test conditions may not be exactly the same as the above data, in which case the performance parameters are standardized data based on standard conditions. The deviation range of water yield is within -20-+25%%% %.
