Hydranautics is Awarded Two Rivers Wisconsin

Hydranautics was awarded the Two Rivers Wisconsin Municipal Ultrafiltration project. The 3.75 MGD (14,200 m3/d) system is scheduled to be delivered in mid-2003. Hydranautics’ HYDRAcap capillary ultrafiltration membranes will be used, with PAC feed for taste and odor reduction, on feed water from Lake Michigan. Bids were received from 5 MF/UF suppliers. Hydranautics was selected for their low operational costs over time, the low cost of the complete UF system package and the performace bond they provided. Hydranautics teamed up with one of their UF Strategic Partners, Indeck Water Treatment Systems of Wheeling, Illinois. Indeck will design and fabricate the system and supply a pilot system to verify flux rates. Pilot testing, beginning Aug. 4th, will run through the summer, fall and winter months as required by the Wisconsin Department of Natural Resources. Carollo Engineers and McMahon Associates are the engineering firms involved in the Two Rivers bid.

Two Rivers is the latest of many ultrafiltration projects awarded to Hydranautics and their Strategic Partners. Some of the more recent projects include Garden City, Missouri and Granbury, Texas both starting up in August and the Butler, Missouri project which will start up later in the year. In addition, Bristol Water, PLC in the UK has surpassed one year utilizing over 7 million fibers at their 15 MGD (56,781 m3/d) plant using Hydranautics’ HYDRAcap membranes, experiencing minimal fiber breakage.

Hydranautics’ new HYDRAcap product line has measured up to the pathogen rejection and economic operation required in the Municipal Market. HYDRAcap capillary ultrafiltration membranes represent state-of-the-art technology and provide superior performance as compared to microfiltration. The technology has exhibited up to 5-log virus removal, thus exceeding USEPA regulations for potable water use as per the Surface Water Treatment Rule. The HYDRAcap UF membrane is added to Hydranautics’ diverse technologies for reverse osmosis and nanofiltration offering various degrees of flux and rejection characteristics, specifically suited to treat multiple and diverse water treatment applications.
