MemTech has developed a game-changing new ultrafiltration (UF) membrane aimed at industrial and commercial water treatment, point-of-use systems, and reverse osmosis pretreatment applications.

The Product & Advantages

MemTech’s UF membrane, which is based on a hydrophilic polymer, has over 2x higher flux capacity (at similar quality) compared to leading commercial membranes. This creates strong competitive advantages —

  • 50% lower capex and opex
  • Smaller membrane footprint
  • Lower pressure operation

MemTech’s next-generation nanomaterial-based membrane has the potential to double this flux rate (to 4x current flux rates), reduce compression, and minimize chemical cleaning.

Background & Market

Membrane filtration plays a key role in meeting water treatment needs. Products that can reduce capital and operating costs, and footprints, will bring about even wider implementation of membrane solutions in the market.

The Company is entering a market that is poised for significant growth. Global demand for membranes is projected to increase 9% annually to over $19 billion in 2015, with ultrafiltration membranes increasing 15% annually to reach $5.8 billion. Membrane sales will be driven by depleting water supplies and increasing demand for water globally (Freedonia Group).
