Abstract
The Southeast Morris County Municipal Utilities Authority’s Clyde Potts Reservoir has been srving the residents of Morristown New Jersey for over 70 years. Over that time the treatment facilities have evolved in response to new water quality regulations. The original treatment, constructed in 1935 was limited to chloramination and pH adjustment with lime. In 1984, the Authority constructed a direct pressure fltration plant in response to the new turbidity standards. In 1998, the Authority constructed a 0.5 MGD demonstration membrane treatment plant to comply with the requirements of the Surface Water Treatment Rule.
The demonstration facility enabled the Authority to assess the effectiveness of this relatively new technology and gain valuable experience and operating data. Based on the operation of the demonstration plant, in 2000, the Authority commenced with the design of a full-scale 2.5 MGD membrane plant. The new plant, which uses immersed membranes was placed into successful operation in November 2004.
