VONTRON RO membrane,
Make of Membrane : VONTRON
Model: ULP21-4040
Origin of country: China
Product Descripitions: ULP Series: Ultra-low pressure Compound RO mebrane Element:
Brief Introduction:
Working under the conditions of ultra low operating pressure, ULP membrane series can achieve as high permeated flow and rejection rate as regular low-pressure membranes can, it rus under approximately two thirds pressure of that regular low pressure compound membranes, and can achieve a rejection rate of as high as 98%.
