Seair closes first portable wastewater treatment unit sale



    EDMONTON, April 28 /CNW/ - Seair Inc. (SDS:TSX Venture Exchange) is
pleased to announce the sale of a Seair 20 foot portable wastewater treatment
unit to SunTerra Oil & Gas LP. This transaction is not only the first sale of
a Seair portable wastewater treatment unit, but is also the first deployment
of a portable wastewater treatment unit outside of Canada.
    Until now Seair has limited its portable wastewater treatment business
model to rental of units owned and operated by Seair. However, potential
customers with long-term needs and/or operating outside of Seair's western
Canadian service area have increasingly expressed interest in owning Seair's
advanced ozone-based wastewater treatment units. This initial sale to SunTerra
marks the expansion of Seair's business model to include outright sales of
treatment units.
    Seair's self-contained and automated portable wastewater treatment plants
are designed to operate under the most demanding of circumstances. The
ozone-based treatment process is unique in that it requires no consumables and
there are no residual solids or sludge after treatment. Seair owns and
operates a fleet of approximately 100 portable wastewater treatment units in
western Canada that can be used independently or combined to meet the
requirements of camps of all sizes.
    Harold Kinasewich, Seair's President and CEO, states "after several years
of refining our technologies and operating our fleet we are excited to allow
other companies, such as SunTerra, to benefit from long-term ownership of our
industry-leading systems. We believe our portable wastewater treatment units
are the most advanced systems available and are well positioned to meet and
exceed increasingly stringent discharge standards. SunTerra's purchase of a
Seair unit not only confirms the value of our system, but also demonstrates
confidence that our system is fully capable of meeting the strictest of
environmental standards."

    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
safety, 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.
    Seair Inc. (SDS:TSX Venture Exchange) is proud to have been selected as
one of the "2008 TSX Venture 50", a ranking of the top 10 public venture
