  • Water and wastewater treatment company, De.mem has launched its new in-house development Microfiltration (MF) membrane
  • A membrane is a barrier that stops small things passing through

Water and wastewater treatment company De.mem has launched its new in-house development Microfiltration (MF) membrane.

The new technology is a hollow fibre membrane with a large pore size and increased flux, which allows greater liquid to pass through.

A membrane is like a barrier as it allows some things to pass through but stops others. These things could be molecules, ions or other small particles.

MF membranes can be used for a wide range of beverages such as wine, beer, diary, and as well in portable and water waste treatments.

The membranes are on a stand-alone basis and is often used as a pretreatment for other separation processes. The new technology pairs well with De.mem’s other technologies such as Nanofiltration and Ultrafiltration technologies.

Ultrafiltration is a proven filtration process based on microporous (2 nanometre) membranes. Separation is achieved based on a process where a liquid is forced through a semipermeable membrane through pressure.

Nanofiltration is similar to Ultrafiltration but uses a semipermeable membrane with pores in the range of 1 – 10 nanometres.

The MF membrane can remove small particles such as sediment, algae, protozoa or large bacteria from a liquid.

De.mem intends to use the new MF membrane for its food & beverage clients, with specific applications such as wine filtration.

De.mem is a Singapore-Australian decentralised water and water waste treatment business that designs, builds, owns and operates its systems for its clients.

Its clients come from the mining, electronics, chemicals, oil & gas and the food & beverage industries as well as in the municipal and residential segments.

CEO Andreas Kroell says this new launch further enhances its product range.

“With the launch of this new product, we are further enhancing our product range in an effort to offer our customer base a comprehensive suite of membrane-based products,” he said.

The global market for Microfiltration membranes and systems is estimated to be at US$6.9 billion by 2026.
