Vontron ULP21-4021 Commercial 21" Reverse Osmosis RO Membrane

You are purchasing a Vontron ULP21-4021 21inch Commercial Reverse Osmosis RO Membrane.

This membrane is capable of producing 950 gallons of product water per day, and is ideal for Window Cleaning applications, along with Aquatics.

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 runs under approximately two thirds pressure of that regular low pressure compound membranes, and can achieve a rejection rate of as high as 99%.
