Alscore design and manufacture of Ultrafiltration water plants to suit industrial and commercial markets with the highest quality standards.

Ultrafiltration is a pressure-driven membrane separation technique used to separate suspended solids from solutions. The pore size of the UF membranes (0.02µm – 0.03µm)  represent a physical barrier against most particles, suspended matter, colloids, bacteria and virus.

Ultrafiltration modules are very suitable for removing turbidity from water, however dissolved substances are not removed by UF modules. Removing dissolved substances will require them to be transformed first into particulate form or the use of other techniques such as Reverse Osmosis.

Like any other filtration method, there are limits to the feed water and pretreatment will be required if the feed water quality is outside those limits. In general turbidity is limited to 50 NTU, TSS are limited to 20 mg/l and TOC is limited to 10 mg/l. Like any other membrane separation method, Ultrafiltration membranes are very sensitive to oil and grease and both need to be removed beforehand if present.

As an example, removal of Iron (Fe) or Manganese (Mn) is dependent on the oxidation state of these metals. They can be removed by Ultrafiltration if they are in particulate (oxidised) form but not if they are in dissolves (reduced) form.
