Dow Water Solutions, a business unit of The Dow Chemical Company (Dow) and a global leader in water purification, seawater desalination, contamination removal and water reuse solutions, announces the acceptance of DOWTM Ultrafiltration membrane modules for drinking water applications. The approval certifies the Dow Ultrafiltration (UF) Module as an Alternative Filtration Technology for treating drinking water. DOW UF modules are used as the core of a complete and well designed, constructed, and operated filtration system for converting surface waters into safe drinking water.
DOW UF has been tested and certified under the California Surface Water Treatment Rule (SWTR), as well as the federal Long Term 1 and Long Term 2 Enhanced Surface Water Treatment Rules (LT1ESWTR, LT2ESWTR). Testing demonstrated the effectiveness of DOW UF in removing harmful pathogens from water and the operational integrity of the modules.
DOW Ultrafiltration’s benefits to the water treatment industry include:
- Ultimate barrier for removing suspended solids and pathogens.
- Pressurized, outside-in flow configuration to handle high-suspended solids, minimizing pre-treatment and lowering capital cost.
- Hydrophilic, PVDF double-wall hollow fibers reduce fouling, have excellent chemical resistance and strength, resulting in durable, long membrane life.
- Fine pores (0.03 um) effectively remove pathogens, most viruses, bacteria, colloids, silt, and other suspended matter ensuring long-term stable operation.
The certification procedure includes an audit of a membrane system’s performance characteristics, and product testing including challenge testing with surrogate particles and viruses according to the protocols in the California SWTR standards.
