Pressurised Membrane Filtration System

American Structurepoint and Black & Veatch will provide design engineering and plant construction services. The system is scheduled for completion in the spring of 2011.

The existing water treatment plant in East Chicago was built in 1964 and has reached the end of its design life expectancy. The deterioration of the plant has resulted in concerns about operational reliability. Because of the multi-million dollar investment needed to rehabilitate and refurbish the existing facility, the City has elected to construct a new treatment plant inland from the current location. Once the new plant is operating, the old plant will be demolished and the land will be incorporated into the Marquette Plan for revitalising the Lake Michigan waterfront.

The Memcor CP pressurized membrane filtration system will consist of six skids, each with 240 membrane modules. This innovative technology is popular with drinking water plants as it offers a lower life-cycle cost and a smaller footprint than conventional treatment systems. It also provides a greater than 4-log removal of Cryptosporidium, Giardia and bacteria, over 1.5-log virus rejection and a silt density index of less than 2.0, regardless of changing feed water conditions.
