Industrial Ultra Filtration Systems

10,000 to 1,000,000 GPD / 38 to 3,785 M3/D

Ultra Filtration is a pressure driven membrane separation process that removes suspended or particulate matter (including colloids & silt) from water. Ultra Filtration is more reliable than conventional multimedia Filtration that removes approx. 10 micron or larger matter where a UF membrane pore size ranges from 0.01 to 0.10 micron. Ultra Filtration also efficiently removes bacteria and most viruses.

Pure Aqua supplies a full line of standard and fully customizable Ultra Filtration systems, all of which are engineered using advanced 3D computer modeling and process design software for accurate and customized solutions

How the Ultra Filtration System Works

The figure below is a typical process flow diagram for a UF system. Ultra filtration 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. The primary flow design is dead-end filtration. Air scouring is used to enhance backwash.
