Features

The DOW™ Ultrafiltration (UF) modules are made from high strength, hollow fiber membranes that have excellent features and benefits:

0.03 µm nominal pore diameter for removal of bacteria, viruses, and particulates including colloids to protect downstream processes such as RO
PVDF polymeric hollow fibers for high strength and chemical resistance allows long membrane life
Hydrophilic PVDF fibers for easy cleaning and wettability that help maintain long term performance
Outside In flow configuration for high tolerance to feed solids that help reduce the need for pretreatment processes
U-PVC housing, helping to eliminate the need for costly pressure vessels

This module is an ideal choice for systems with capacities greater than 50 m³/hr (220 gpm). Larger and longer, 8 inch diameter and 80 inch in length, together with an increase in packing density of 10,000 fibers, this module offers the highest effective membrane area of the DOW™ Ultrafiltration modules. The 2880 contributes to a more economical membrane system design.

DOW™ Ultrafiltration Modules can be used for a wide variety of treatment applications such as surface water, seawater, industrial wastewaters, and secondary effluent wastewater.

Important information

Proper start-up of a UF system is essential to prepare the membranes for operating service and to prevent membrane damage. Following the proper start-up sequence also helps ensure that system operating parameters conform to design specifications so that system water quality and productivity goals can be achieved. Before initiating system start-up procedures, membrane pretreatment, installation of the membrane modules, instrument calibration and other system checks should be completed. Please refer to the product technical manual.

Operation guidelines

Avoid any abrupt pressure variations during start-up, shutdown, cleaning or other sequences to prevent possible membrane damage. Flush the UF system to remove shipping solution prior to startup. Remove residual air from the system prior to startup. Manually start the equipment. Target a permeate flow of 60% of design during initial operations. Depending on the application, permeate obtained from initial operations should be discarded. Please refer to the product technical manual.

General information

If operating limits and guidelines given in this bulletin are not strictly followed, the limited warranty (Form No. 795-00027) will be null and void.

To prevent biological growth during system shutdowns, it is recommended that preservative solution be injected into the membrane modules.
