De.mem extends hollow fibre range


Water and waste water treatment company, De.mem, has broadened its product range with the launch of different variations of its low pressure hollow fibre nanofiltration (NF) membrane technology.


The company recently unveiled its new Ultrafiltration (UF) membrane based on the company¡¯s core technology. UF is a physical separation process which generally removes particles with a size range from 0.005 to 0.1 ¥ìm from a fluid.


UF membranes are often used for the removal of bacteria, viruses and other particles, and have applications in potable water, sewage as well as industrial waste water treatment, key markets for the company. The separation technology is also used for the pre-filtration stage in Reverse Osmosis (RO) water treatment plants or for domestic water filtration.


The new UF membrane has a relatively small pore size for a UF membrane and has been successfully tested by De.mem for highly efficient (¡°6-log¡±) bacteria reduction using E.coli.


De.mem has also launched two variations of its hollow fibre NF technology with very small or tight pore size. One version of the NF membrane is optimised for maximum ¡°flux¡± (volume of clean water produced), and another version has minimum pore size for highest reduction of contaminants. Both types of NF membranes operate well under low pressure of 1 to 2 bar feed pressure.
