FAIRFIELD, CA, Aug. 10, 2005 -- ProTech General Contracting Services Inc., a full service environmental compliance company, announced that the U.S. Patent and Trademark Office has issued Patent 6,899,808 B1 to the company for its Sediment Removal System (SRS). The SRS is the basis of ProTech's line of modular, flow-through water filtration technologies, designed to remove suspended sediment and contaminants from stormwater runoff, construction dewatering, and many other sources.

The patent is in effect beginning May 31 and will remain in effect for a period of 20 years. For details, see: U.S. Patent & Trademarks.

"ProTech developed the SRS to provide the best possible sediment removal efficiency in a portable water treatment system," says Chris Ott, ProTech's Chief Technology Officer. "The SRS design includes several unique features that combine to minimize turbulence, improve settling efficiency, and optimize the flow path. This Patent is another demonstration of how ProTech is leading the stormwater treatment industry."

The ProTech SRS is compact, reliable, and quick and easy to set up. The standard SRS has a 4,000-gallon retention capacity, with a flow rate of up to 250 gallons per minute, depending on water characteristics. The SRS can be installed as a mobile filtration system, or it can be installed in an underground vault configuration. It can operate as a stand-alone sediment removal system, or can be configured with a variety of optional components as required to remove virtually any contaminant. Oil/water separators, cartridge or membrane filters, polymer coagulants, and chemical treatment systems are readily added. The SRS can also be equipped with automated control systems, instrumentation, and remote sensors designed to page the operator and report operational parameters.
