    Introduction

    ESPA(Energy Saving Poly Amide) series reverse osmosis membrane , it has ultra-low operating pressure .maintaining high desalination rate is characterized by high water flux and wider water quality application range and pressure application range, ESPA series membrane is characteristic by high water flux and high desalination rate . the cost of equipment manufacturing is reduced. system operation cost reduced .it can save a lot of energy.

    Feature

    1.ESPA series has higher specific water flux, the ESPA4 reached 72.6LMH/Mpa, it’s one of the reverse osmosis membrane in the world for water flux.
    2.ESPA2MAX the membrane area increased by 10%. Up to 440 ft² ,this allows the ESPA2MAX to highest membrane salinity of the ultra-low pressure series at the same time, reached high water yield, and water flux reached 4.0LMPa .
    3.ES width is the highest boron element removed of 96%.

    ApplicationESPA series ultra-low pressure reverse osmosis can applicable to industrial pure water , municipal , light industry and drinking water. Even in the deep treatment and recycling of municipal sewage. PROCTM
