ESPA Series:

Energy-efficient ultra-low pressure RO Membrane ESPA® 。Currently,ESPA®Series 8-inch membrane, there are five models: ESPA1 (standard ultra-low pressure reverse osmosis membrane), ESPA2 (high rejection rate of ultra-low pressure reverse osmosis membrane), ESPA4 (ultra-high volume low pressure reverse osmosis membrane), ESPA2 MAX (high membrane area of the high rate of ultra-low pressure reverse osmosis membrane desalination) and ESPAB (high boron removal reverse osmosis membrane ultra-low voltage), 4-inch membrane has developed into three types: ESPA1-4040, ESPA2-4040 and ESPA4-4040.
