Ultrafiltration Membrane System

Ultrafiltration (UF) technology uses a membrane barrier to exclude particles as small as 0.01 microns, including bacteria, viruses and colloids. Advantages of UF compared to conventional treatment such as clarifiers and media filters, are its high tolerance to feed water quality upsets, absolute barrier and improved water quality.

UF offers:

0.03 μm nominal pore diameter to facilitate high removal capability for bacteria, viruses and particulates including colloids.
PVC/PVDF polymeric hollow fibers for high strength and chemical resistance.
Hydrophilic PVC/PVDF fibers for easy cleaning and wettability to help maintain long-term performance.
Outside-In flow configuration for high tolerance to feed solids and the use of air scour cleaning.
U-PVC housings eliminate the need for pressure vessels and are resistant to UV light.

When used as a pre-treatment for reverse osmosis (RO), UF also helps reduce fouling of RO membranes, which can lead to:
Reduced chemical cleaning frequency and consequently, lower operating costs and downtime.
The potential to operate RO at higher flux, with fewer membranes and vessels – leading to lower capital cost for the RO system.
