Membrane Bio Reactor System

Watterson is one of the main distributor for SUMITOMO™'s POREFLON® Membrane Module for wastewater treatment solutions. By using PTFE or polytetrafluoroethylene to create a separation membrane for the MBR membrane module, the POREFLON® module is highly resistant towards O&G and chemical thus making it more durable and long lasting.

With a high porosity (percentage of void) of between 75% to 85%, it greatly reduced the resistance which occurs during penetration, thus show a high permeability of the membrane structure. Beside that, a double-layer PTFE structure which is made up of skin layer (filtration) and a support layer provides a far more superior resistance to fouling on the PTFE membrane.

Comparing to conventional organic membranes, POREFLON® has more higher strength which contributes to a more prolonged operation and longer lifespan

The use of PTFE membrane with high durability provided by the hydrophillic treatment combine with an asymmetric (dual) structure offers superior resistance to fouling

PTFE membrane allows cleaning with strong alkali

The “U-Shaped Structure” employed at the end bottom prevents active sludge accumulation and allows efficient air diffusion
