Diffused ozone shown to be effective in treating oil sands process water



    EDMONTON, March 31 /CNW/ - Seair Inc. (SDS:TSX Venture Exchange) is
pleased to announce the release of independent study results that confirm
ozone diffused into oil sand process water eliminated more than 95% of the
naphthenic acid present in the water samples. The study, done by researchers
at Syncrude Canada Ltd. and the University of Alberta, is believed to be the
first experimental evidence that ozone can react with naphthenic acids.
    Oil sand process water ("OSPW") arises from the hot alkaline extraction
process used at the oil sands deposits in northeastern Alberta. The extraction
process water contains dissolved naphthenic acids that are acutely toxic to a
range of organisms and, therefore, must be eliminated if the OSPW is to be
released back into the environment. Biodegradation is generally used to
mitigate OSPW toxicity but naphthenic acids are very resistant to
biodegradation.
    Using Seair's patented diffusion process, ozone concentrations of
approximately 35 mg l-1 were achieved in OSPW from Fort McMurray, Alberta.
After 130 minutes of reaction time the naphthenic acid presence in the OSPW
reduced from 59 to 2 mg l-1, or more than a 95% reduction.
    Harold Kinasewich, President and CEO of Seair, states "we are pleased to
now have independent verification that Seair's micro-bubble ozone diffusion
can be an effective means to treat one of the most challenging aspects of oil
sands tailing pond remediation. Our work in other industries has shown that
Seair's solutions not only get results, but do so in a very cost-effective
manner. We are now prepared to work with government and the oil sands industry
to eliminate naphthenic acids from oil sands process water on a commercial
scale."
    The study results by A.C. Scott, W. Zubot, M.D. MacKinnon, D.W. Smith and
P.M. Fedorak were published in the international journal Chemosphere, Volume
71, Issue 1, March 2008, Pages 156-160. The full article, entitled "Ozonation
of oil sands process water removes naphthenic acids and toxicity" can be

    About Seair

    Seair is a leading developer of patent-protected diffusion and
sterilization technologies, which allow for the efficient diffusion of gases
into liquids, thereby facilitating numerous applications in a wide variety of
industries, including wastewater treatment, pulp and paper production, food
processing, aquaculture, agriculture/horticulture, sterilization, golf course
irrigation and pond treatment, animal enhancement and oil and gas. Seair's
primary focus is developing and selling equipment that diffuses gases, such as
oxygen, ozone or carbon dioxide, into a liquid, resulting in a supersaturated
solution. The major difference between Seair's and others' diffusion
technologies is Seair's ability to achieve extremely small bubble size, which
in turn allows for the mass transfer of gas to fluid. The result is a stable
condition, where gases remain in solution for extended periods of time,
leading to increased productivity and lower operating costs. Seair provides
diffusion-enhanced portable wastewater treatment plants through its
subsidiary, Seair Septic.
