Ultrafiltration System

TST Water’s Ultrafiltration system is a low-pressure membrane process, capable of removing colloidal materials, finesuspensions, bacteria, virus, cyst, suspended solids and organic materials down to 0.02 micron.

Engineered for convenience, the UltraGuard® line allows for simple installation utilizing industry recognized sump and housing configuration. Verifiable membrane efficacy allows the installer to provide a true tested protective barrier on every installation as well as during service calls. High surface area of the UF membrane requires normal line pressure to operate, low backflush waste while delivering high flow with low pressure drop. WQA Certified against the US EPA Guide Standard and Protocol for Testing Microbiological Water Purifiers providing a certified bacteria, virus and cyst barrier.

UltraGuard® UG-2001 comes complete with two stages of filtration. Stage one is a gradient density 25 micron depth sediment filter. This filter provides protection to the membrane by filtering out sand, silt, sediment and rust that may be preset in the water.

Stage two is our Made in USA Ultrafiltration double skinned hollow fiber element which are made from polyethersulfone (PES). PES is a hydrophilic, chemically stable polymer capable of operating in aggressive environments while providing high flow rates and sub micron filtration. TST Water’s Ultrafiltration hollow fibers have separation layers on both sides of the fiber (double skinned), providing superior separation filtration and high recovery during back flush.
