Reverse Osmosis & Nanofiltration

Reverse Osmosis & Nanofiltration

Wigen is a leading provider of industrial and municipal RO and NF systems with capabilities that include engineering, manufacturing, site supervision, commissioning and operator training. We’ve designed and built RO and NF systems since the late 1990s and have hundreds of successful installations throughout North America. Like the rest of our products, all of our RO and NF systems are designed and built for the clients’ specification applications. Taking into account the influent water quality and temperature, as well as permeate and concentrate requirements, Wigen is able to create custom solutions that are cost competitive with others’ catalog offerings. Systems can range in size from a few gallons per minute to millions of gallons per day. Most of our designs include the required pretreatment systems (equipment and chemical) in order to reduce or eliminate fouling and scaling of the membranes.
