UET Water Ultrafiltration Systems

UET Water 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

UET process engineers have a long history designing and installing the Ultrafiltration systems.


UF can be used for removal of particulates and macromolecules from raw water, to produce potable water. It has been used to either replace existing secondary (coagulation, flocculation, sedimentation) and tertiary filtration (sand filtration and chlorination) systems employed in water-treatment plants or as standalone systems in isolated regions with growing populations. When treating water with high suspended solids, UF is often integrated into the process, using primary (screening, flotation and filtration) and some secondary treatments as pre-treatment stages. Ultrafiltration processes are preferred over traditional treatment methods for the following reasons:

1. No chemicals required (aside from cleaning)

2. Constant product quality regardless of feed quality

3. Compact plant size

4. Capable of exceeding regulatory standards of water quality, achieving 90-100% pathogen removal.

When water recycling is simple, it often needs very little processing.  However,   when more intensive processing is required, the industry standard procedures include using UF, which is meant to remove physical solids from water by passing it through a semi-permeable membrane.  Using ultrafiltration, solids are primarily captured by the filter and discarded.

Recycled water can also be used for a number of industrial purposes, including boiler or cooling tower feed water supplementation, pH adjustment, washing equipment, hardstands and vehicles, fire protection, process rinse water or processing water for production lines in manufacturing industries, toilet flushing, dust control, construction activities, and concrete mixing.
