Ultrafiltration is a pressure-driven membrane separation process that removes suspended or particulate matter (including colloids & silt) from water. Ultrafiltration is more reliable than conventional multimedia filtration that removes particles of 10 microns in size or larger. Ultrafiltration also efficiently removes bacteria and most viruses.

Ultrafiltration systems eliminate the need for clarifiers and multimedia filters. Standard design is based on a UF module with outside-in flow configuration which allows for less plugging, higher solids loading, higher flow area and easy cleaning. Pure Aqua supplies a full line of standard and fully customizable Ultrafiltration systems, all of which are engineered using advanced 3D computer modeling and process design software.
