Who is Nutech O3?

Nutech O3 has developed technology that will eliminate the problems created by aquatic nuisance species, of all types. Nutech has been working on solving the problem since 1998. The technology that we have developed is environmentally safe, and economically affordable. Nutech's effort includes both extensive at-sea, on-board ship, testing of its patented process and extensive laboratory testing, the bulk of which is being conducted at the University of Washington's Merristone Test Center in Puget Sound, near Seattle, Washington.

Both the completed (Mark II), and planned (Mark III), at-sea testing are being carried out on board British Petroleum oil tankers operating in the Pacific Ocean between Valdez, Alaska and oil refineries located near Seattle, Washington, and in San Francisco and Long Beach, California. Additional, fresh water testing, on freighters operating on the Great Lakes, is being planned for 2006.

» Company History

Nutech O3, Inc. was founded in 1997. Our initial mission was to expand the use of ozone into the commercial laundry industry. Our first installation was successful, reducing water consumption, chemical use, and energy costs by over 50%. Ozone was used to clean water so that is could be re-used in the wash process. Ozone was also applied directly into the washers, reducing the temperature at which linen could be washed and the amount of chemicals needed to adequately clean the linen.

In 1998, British Petroleum sought Nutech's assistance in solving the invasive species problem. BP asked if Nutech could modify its waste water recycling technology so that it would remove invasive aquatic nuisance species from its oil tanker's ballast water. Nutech O3 started design work in late 1998 and began testing its ballast water treatment technology on the T/V Tonsina, a 125,000 ton oil tanker owned by British Petroleum, in 2000. The Tonsina regularly delivers Trans Alaska Pipe Line oil from Valdez, Alaska to oil refineries Seattle, Washington and Long Beach, California. It carries 12 million gallons of ballast water. Four years of on board ship and laboratory testing has proven that ozone is an exceptionally effective biocide for removing invasive aquatic nuisance species from ballast water without increasing the corrosion in the ship's hull or harming the quality of the water into which the treated ballast water is discharged.

In 2004, Nutech O3 was awarded a grant from Congress to further test the effectiveness of ozone in eliminating aquatic nuisance species from ballast water. More on this project can be found in the recent projects section of this website.
