WILMINGTON, MA, Sept. 19, 2005 -- Koch Membrane Systems Inc. announces that MECO, of New Orleans, has selected KMS to supply RomiPure® hollow fiber ultrafiltration (UF) membranes and Fluid Systems® TFC® spiral reverse osmosis (RO) elements for use in the U.S. Army's Lightweight Water Purification units (LWP).

LWP is a portable water purification unit designed to fit into the cargo space of a High Mobility Multi-Purpose Wheeled Vehicle (HMMWV) and can be transported in a single lift of a UH-60 Blackhawk Helicopter. UF hollow fiber membranes are used in the LWP as pretreatment for RO spiral membranes by removing turbidity, suspended solids, bacteria and other microorganisms from the feed water that can foul the downstream RO membranes. RO membranes remove salt and very small organic components to produce fresh water that is suitable for drinking. Membrane processes have been selected for the LWP because they reliably produce fresh water while keeping equipment space and weight to a minimum. Another advantage is low chemical consumption and reduced waste generation as compared to other types of water treatment processes.

Fresh water produced by the LWP will support both military operations and humanitarian missions, including disaster relief and refugee care. Design capacity of the LWP is between 75 and 125 gallons per hour of fresh water when treating a wide variety of feed waters including turbid or brackish water, seawater, and water with nuclear, biological or chemical contamination.

MECO designs, constructs and services water purification equipment and systems for critical applications in various markets. The company has been serving the U.S. military since WWII when its then patented technology was used throughout the European and Pacific theaters. MECO is the North American market leader in the development of biopharmaceutical water systems used in drug manufacturing. The company also provides desalination plants and services to the marine oil and gas industry. MECO will supply several hundred LWP units during a five-year production contract with the U.S. Army Tank and Automotive Command (TACOM).
