Equivalent DW74-1100 DOW Ultrafiltration Membrane Modules UF Membrane Modules

Introduction:

The equivalent DOW DW74-1100 Ultrafiltration Membrane Module offers one of the largest membrane areas in the industry in a shorter module format. It is an excellent choice for containerized system designs where its large filtration area and short height can contribute substantially to system savings.

Equivalent DOW DW74-1100 Ultrafiltration 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.

DW74-1100 Ultrafiltration Membrane Module's features:

• 0.03 µm pore size which facilitates reduction of most common bacteria, viruses, and particulates, with filtrate SDI <2.5

• 74 m2 of filtration area in a shorter module format to facilitate system designs with height constraints

• 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 with less packing density limiting fouling and improving removal of suspended solids
