Simple design, superior performance, and outstanding economics – Filken ultrafiltration system sets the standard for treated water applications.

Filken’s membrane is based on Polysulfone (PS) material with one of the highest membrane packing densities per cartridge available in the market. Polusulfone membranes exhibit a wide pH tolerance (continuous exposure range of pH 1- 13), high temperature limit (typically 75 °C), good oxidant resistance (chlorine exposure: storage 50 mg/L, short-term sanitation 200 mg/L, >106 ppmh).

Filken’s Hollow fibre is a flexible membrane; it can carry out the filtration by either ''inside-out'' or ''outside-in''. Filken’s cross flow hollow fibre membrane also reduces fouling as the fluid flows from the inside of the hollow fibre and pass through to the outside of the membrane. Despite the size of the hollow fibre membrane being smaller than other types of membrane, its circular structure allows a higher surface area which in turn, yields a higher performance.
