I want to tell you about a truly unique ozone diffusion process that I'm certain will stir up a lot of interest in the wastewater community. At the end of this story, I'll offer an article download that is completely scientific; as it was prepared for submission to an Australian Water conference. But since this is a blog, I'm told I'm allowed to let a little personality show through before getting down to the science.To give you a feel for how taken I've become with this technology, I'd like to share the unlikely circumstances that brought me to representing Seair Diffusion Systems in Australia. I first found out about Seair while working as a Golf Professional at Wolf Creek Golf Resort, in Alberta, Canada. I became curious about the pumphouse box that housed our watering system; so I asked the golf course superintendent "Mate, what's the go?" He told me he was 'super-oxygenating' the irrigation water - increasing the "DO levels" with ambient air using these diffusion towers.
That was a few years back, and it was the start of becoming involved with Seair and introducing the technology here in Australia. As I mentioned the Seair process uses Ozone. As everyone reading this blog knows, ozone is a strong oxidant and will react with unsaturated hydrocarbons very effectively. It has been used in wastewater treatment for decades as a form of tertiary sterilization. But it is generally thought to be too expensive to produce, and very wasteful to use simply as a tertiary treatment process. Ozone, however, combined with Seair`s patented diffusion technology can do much more. Ozone combined with microbubble diffusion allows for extremely high mass transfer of the gas to wastewater. This means creating a supersaturate solution of ozone with little to no off gassing in a very stable state. Supersaturate ozone solutions allow reactions with unsaturated hydrocarbons to happen faster, but also push reactions that typically would not happen in less concentrated solutions. BOD, COD, TSS and bacteria are now easily eliminated very efficiently and economically, as a result there is no primary or secondary sludge formation
The key to Seair’s systems is the ability to efficiently diffuse ozone and oxygen gas into the wastewater stream. Seair’s diffusion system produces 5 micron sized bubbles through the Seair’s patented diffusion chamber. The micro-bubbles dramatically increase the available surface area for reaction and result in an extremely stable super-saturate solution. Gas remains in solution for extended periods of time, which facilitates maximum treatment results and minimal off gassing.Seair utilizes a patented process where ozone is used in primary, secondary and tertiary treatment processes representing a best practice wastewater solution. This technology has been proven in the harshest environment, Northern Canada, and has expanded to small communities, remote industrial mining and exploration sites which face considerable challenges to implement environmentally and economically viable wastewater treatment solutions. Seair`s patented wastewater treatment system will meet or exceed any government regulation for discharge.
You can dowload our study, "Ozone Based Wastewater Treatment Solutions" (PDF, 10 pages) - Download file. The focus of this study is the evaluation of the effectiveness of an advanced diffusion system’s ability to use ozone and oxygen in the treatment of wastewater. This report involves a detailed examination of the Seair 12m Portable Wastewater Treatment Plant (PWW40). The patented ozone-oxygen-ozone based wastewater treatment system is available in a packaged portable unit.
