HYDRAMEM Brackish Water RO Membranes  are designed and engineered to provide finest performance in terms of permeate flow and quality. Each membrane is rigorously tested on all parameters to ensure guaranteed and consistent performance. The types of membranes used in Reverse Osmosis (RO) water purifiers have the smallest pores and their pores are so small that it is just a little larger than the size of a water molecule and so it will allow pure water molecules to pass through easily, but will stop the passage of larger molecules of salts and organic chemicals.
