After extensive testing, GEA Filtration has pioneered the state-of-the-art Reverse Osmosis Polishers (ROP) membranes to achieve significant energy savings. The newer polisher membranes allow operation at lower feed pressures and can be installed in existing or new membrane ROP plants. GEA Filtration has experienced a 35% reduction in the operating pressures and a horsepower reduction of up to 30%.

The membranes cost is similar to standard polisher membranes but, due to lower operational costs, the added savings results in considerable annual savings. Lower energy consumption not only reduces operating cost, but it also is beneficial for the environment at the same time. The cost advantage on new plants is twofold:

•    the capital costs of a new plant are reduced by up to 10% due to the need for fewer pumps to achieve the operating pressure

•    the reduced power requirements

With water availability and the ever growing environmental challenges, this is an excellent proposition for numerous polisher applications as production facilities are expected to use water more efficiently and effectively. GEA Filtration is working with customers every day to develop new ways to treat, reuse and reclaim the water. With its process and system know-how, the GEA team applies process options to meet the site-specific demands of each facility. Additionally, GEA Filtration offers various pilot plant units for product testing and new waste stream treatment feasibility. These plants are available through a rental program for testing at your plant site or in its pilot plant testing facility in Hudson, Wis.
