Why Us?

3E Memtech Pte Ltd tracks its origin back to the research work that was conducted in Prof Neal Chung’s lab in National University of Singapore. Prof Chung’s research group was recognized as the global top one in the field of membrane separation, desalination, and water reuse by Lux Research in 2013. It laid a solid foundation of our hollow fibre nanofiltration membranes. Till date, we are still working closely with Prof Neal Chung and Prof Zhang Sui’s groups to develop and commercialize cutting-edge membrane technologies.

Enabler of our strength: proprietary process

Traditional Nanofiltration Membrane Manufacturing Method

Most of the hollow fiber membranes are made in a two step manner: base membrane and coated with selective layer on top. This process creates yield issue in production and delamination issue in application, leading to high opex and capex for end users.

NF Fibre Yield Rate: 99.8%

Module Fab

Module Yield Rate: 99%

Module Coating

6’’ and Above Module Yield Rate:<60%

Max Product Yield Rate: 50.3%

Our Proprietary One-Step Manufacturing Method

3E-NF is cast in a one-step manner: dense and supporting layers are formed in one step. This is enabled through our years of research on formula and production. Our proprietary process increases the yield of membranes and eliminates the delamination issue. As such, end users could ensure lower capex and opex.
