Membranium Membrane Elements & Flatsheets

So Pure Enterprises is the supplier of world renowned and trusted water and waste water equipment and we are proud to have established a new partnership with Membranium.


MEMBRANIUM is a unique Russian company fabricating nanostructured membrane flatsheet and membrane elements for reverse osmosis (RO), nanofiltration (NF), ultrafiltration (UF) among the world’s manufacturers of membrane production. We are professional and dedicated team of experts united by one goal – to bring national membrane science and technology to the leading position in the world.

MEMBRANIUM membranes application allows:

  • To ensure availability of healthy and safe drinking water;
  • To provide advanced processing of dairy and other agricultural raw materials, and eliminate environmental pollution with food production waste;
  • To realize idea of water “third tap” in new residential buildings in order to provide people with high quality drinking water.
