MEMBRANE STRUCTURE

Memfil Ultrafiltration membrane cartridges operate from the inside to the outside during filtration. This means that process fluid (retentate) flows through the center of the hollow fiber and permeate passes through the fiber wall to the outside of the membrane fiber. Tangential flow can help limit membrane fouling. Other operating techniques that can be employed with hollow fiber ultrafiltration membrane systems include back flushing with per-meate and retentate reverse flow.
Ultrafiltration

Ultrafiltration can be used to apply to the following :
  1. Surface Water Clarification
  2. Waste Water Treatment
  3. RO Pre-Treatment

Surface Water Clarification :
This membrane can be used to replace all conventional clarifying processes, eliminating the need for coagulant and flocculant and large clarifying tanks, media and sand filters. Without the need to use large clarifying tanks, one would conserve much valuable land. The system is neat and takes up a very small footprint. For example, a 500m3/day UF system takes up only 2.4m x 1.2m of space. It is suitable for treating incoming piped water, all surface water such as reservoirs, lakes, rivers, canals, rain and bore-hole or, underground water.

Waste Water Treatment :
In using the the 'Ultra-Flo' membranes in replacing the conventional clarification process, there is no need to use chemicals such as, coagulant and flocculant. The membranes are made of modified hydrophilic poly acrylic nitrile. Eliminating the use of chemicals will assist in further savings,besides saving on labour, as manpower is usually required in theaccurate dosing of chemicals required in the conventional water treatment plant.
