Dow to Develop Filtration Devices Using Argonide Electropositive Technology

By Chemical Processing staff

May 07, 2013

Dow Water & Process Solutions and Ahlstrom Advanced Filtration will develop a line of filtration devices to address drinking water needs in the point-of-use markets using Argonide Corp.’s NanoCeram technology. NanoCeram is an electropositive non-woven pleated filter with an average two-micron pore size, which is effective at filtering sub-micron particles at high flow rates. It is used extensively in residential, commercial and industrial water purification.

Ahlstrom's Disruptor filter media which is under license from Argonide. In 2006, Argonide licensed Ahlstrom to manufacture non-woven filter media using Argonide's NanoCeram electropositive filtration technology. Ahlstrom's brand name for NanoCeram technology is Disruptor.

NanoCeram filters are suitable for use as prefilters for other systems including RO membranes, UV chambers and ion exchange beds. They exhibit efficient turbidity reduction and SDI values between 0.5-1.0 provide. NanoCeram filters are also used in a polishing mode to increase final feedwater quality. As part of a filtration system, this technology can further reduce contaminants such as colloidal solids, organics, virus, endotoxins and trace pharmaceuticals.
