First Large Scale North American Ultrafiltration System Using Toray UF Modules Starts Up

Share Article

A 2-MGD ultrafiltration system commissioned by Wigen Water Technologies in New Town, North Dakota in June 2011 is the first large scale municipal system in the United States to utilize Toray’s HFS-2020 UF membrane modules.

After the first few months of operation at both the Newtown and Mandaree installations we have not had a single fiber breakage detected at start-up or during ongoing operation.

The startup of the New Town system signals a serious new entrant into the municipal UF market. This facility, project managed by Bartlett & West, is one of three UF systems ordered from Wigen Water Technologies for the Fort Berthold Indian Reservation to meet the demand for improved drinking water infrastructure which has been driven by the oil boom in the region. A 1.4 MGD system at Mandaree, ND commissioned in July 2011 also uses Toray’s UF membrane modules, as will a 1.0 MGD system at Twin Buttes, ND scheduled to start-up in early 2012. Each of these systems draws water from Lake Sakakawea which is located on the upper reaches of the Missouri River.

“We have had a very positive response to our entry into the UF market from engineers and municipalities and with the availability of the Toray UF membranes to complement our Reverse Osmosis equipment, we can now provide fully integrated membrane systems” said Jeff Wigen, President of Wigen Water Technologies. “Our first integrated UF/RO system is a 4.5 MGD installation currently under construction and due to start-up later this year” said Wigen.

Toray’s HFS-2020 module is a pressurized outside-in module with hollow fiber PVDF (Polyvinylidene Fluoride) membranes having a nominal pore diameter of 0.02 µm. The membrane surface area in each module is 775 ft2. With such a high surface area per module and approval by the Californian Department of Public Health (CDPH) for at least 4-log Giardia and Cryptosporidium removal at a maximum flux of 120 gfd, UF systems using Toray’s HF-2020 module have a smaller footprint than other commercially available UF systems and therefore potentially a lower overall capital cost.

“Our UF membranes are manufactured using the Thermally Induced Phase Separation (TIPS) process which produces a membrane that is much less susceptible to breakages compared to many of the more established UF membranes on the market” commented Mike Stefanic, Product Manager of Toray Membranes USA, Inc. “We therefore see significant potential for our UF module in the municipal drinking water market where fiber breakages have become a significant issue in recent years.”

“After the first few months of operation at both the Newt Town and Mandaree installations we have not had a single fiber breakage detected at start-up or during ongoing operation” said Wigen. “We are excited to be able to manufacture such a high quality UF system at very competitive prices”.
