STUART, Fla., May 2, 2011 (GLOBE NEWSWIRE) -- Ecosphere Technologies, Inc. (OTCBB:ESPH), a diversified water engineering and environmental services company, today announced that the U.S. Patent and Trademark Office has issued a formal Notice of Allowance for a fourth Ecosphere patent to treat industrial wastewaters and potable waters. Over the last fourteen months, Ecosphere has received four patents for its core Ozonix technology.

The patented Ecosphere Ozonix Technology is a high volume, advanced oxidation process designed to clean and recycle water without the use of chemicals.

Approximately 520,000 gallons of chemicals have been eliminated from hydraulic fracturing operations as a result of the Ozonix technology being used in place of chemical biocides and scale-inhibitors.
