3M Liqui-Cel Membrane Contactors have a long history of improving a variety of water treatment systems by adding and/or removing dissolved gasses in many industries. Typical industries include Semiconductor, Beverage, Pharmaceutical, Power Generation, Digital Printing and many others. 3M Liqui-Cel Contactors were recently selected among competing technologies to be used in a municipal environment to improve water distribution efficiency while reducing capital and operating costs.
United Water New York (UWNY) operates the water supply and distribution system throughout most of Rockland County. There are forty-five wells in the water supply system. Two of these wells in the New Hempstead region contained high levels of entrained/dissolved gas forcing the wells to operate below their optimal flow rates. Running higher flow rates generated an increase in customer complaints about cloudiness of the water. Additionally, any dissolved air that entered the distribution system could accelerate corrosion and cause reduced carrying capacity in main lines, particularly those that are made of unlined cast-iron pipes.
