Introduction:
The replacement DOW DW102-1100 Ultrafiltration (UF) Membrane Module offers one of the largest membrane areas in the industry. It is an excellent choice for larger systems where it can contribute substantially to system savings by reducing fittings, frame materials, operating trains, valve stacks and overall system footprint.
Replacement DOW DW102-1100 Ultrafiltration (UF) Membrane Modules can be used on a wide variety of water sources, such as groundwater, surface water, and seawater to help produce safe drinking water.
DW102-1100 Ultrafiltration (UF) Membrane Modules' features:
102.5 m2 of filtration area to facilitate substantial reduction of capital costs for larger systems
PVDF fibers free of macro voids which offer excellent break resistance, chemical and fouling resistance; which facilitates extended membrane life and consistent long term performance
Outside-In flow configuration which facilitates operation in higher TSS feed waters, while maintaining reliable system performance and producing high quality filtrate
Streamlined PVC housing allows room for more fibers at lower packing density, reducing fouling and improving removal of solids
