Abstract
Ultra-low pressure RO membrane module “ES series” and high performance under operating pressure of 0.7 MPa. The ES series requires about half of the operating pressure as most commonly available aromatic polyamide composite RO membranes, so they can save energy costs and initial costs.
The ES series consist of 3 types, that is, “ES10”, “ES15” and “ES20”. “ES10”, is a base grade, in which NaCl rejection is 99.5% and permeate flux is 30 m3/day at 0.7 MPa. “ES15” has higher permeate flux, and “ES20” has higher NaCl rejection than that of ES10. All types have 2 grades for their usage, that is, desalination of tap water and making of ultra pure water.
