EDMONTON, June 25, 2008 (CNW) - Seair Inc. is pleased to announce Canfor Pulp and Paper Ltd. has completed the comprehensive trial and testing of a Seair SA600 system. With the successful conclusion of the trial, Canfor has acquired the SA600 system and placed an order for a second, identical, system.
Canfor initially tested and subsequently purchased a Seair SA400 system in October 2007 at their Taylor, British Columbia mill. In early 2008 a much larger SA600 system was installed at the Taylor mill for commercial scale testing in the aeration pond. The objective of the trial was to assess both the pure aeration effectiveness of the SA600 and the required energy consumption in a variety of operating conditions.
Craig Thomson, Energy and Environmental Supervisor at the Canfor mill, states "the Seair SA600 is remarkable. Our mill succeeds when we increase the frequency and duration of hardwood runs, and since installing the SA600 we've set multiple hardwood records. Seair's equipment, by very efficiently maintaining high dissolved oxygen levels in our aeration pond, has been a major contributor to these record results. We will now be proceeding with a full measurement and verification ("M&V") study, which we expect to complete in the next 30 days, to definitively quantify the productivity gains and energy savings generated by the Seair SA600."
Canfor is using Seair's patented diffusion towers to increase dissolved oxygen levels in the mill's aeration pond. Ambient air is run through the diffusion towers to produce a micro-bubble aeration process where the amount of available oxygen is increased and the aggregate surface area of the oxygen bubbles is 1,000 times greater than conventional fine bubble diffusion systems.
Harold Kinasewich, Seair's President and CEO, adds "the Canfor implementation proves Seair has the definitive aeration solution for pulp mills and other industrial situations involving large aeration ponds. Our equipment achieves superior results and reduces energy consumption by up to 80% relative to other aeration systems."
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.
