Our History

The Great Lakes Clean Water - Limited Partnership has been working on and developing WATERCLEAN™ since 2001.   The performance has been verified by Ontario New Technology Evaluation (NETE) in 2006 and by ETV Canada (Environmental Technlogy Verification) in 2009.  In 2013, 2014, & 2015, we tested a fourth generation Residential WATERCLEAN™ machine at the Centre for Alternate Wastewater Treatment (CAWT) in Ontario and have significantly improved test results which meet or exceed the requirements specifications of the Bureau de normalisation de Québec (BNQ) Standard BNQ 3680-910 and the NSF International Standard NSF/ANSI 350.


The WATERCLEAN™ machine is like a household appliance, it is a wastewater washing machine.  It is much like a washing machine for clothes.  It has a fill cycle, a wash cycle, a discharge cycle; it uses ozone in place of soap, and washes wastewater in place of clothes.


The WATERCLEAN™ wastewater treatment system is based on well-established principles of advanced oxidation, using a batch reactor under closed loop conditions.  The system equipment includes a compressor, an oxygen concentrator, an ozone generator, a multi-stage centrifugal pump, ozone injection, flash mixing, a pressurized extended treatment conduit, a sparger/atomizer, a reactor tank, an off-gas destruct arrangement, and a diverter valve, all automatically controlled by a programmable system controller.


The WATERCLEAN™ system takes in atmospheric air, compresses it, removes the oxygen and concentrates it, generates ozone, injects the ozone into the wastewater stream, flash mixes it, pressurizes it, atomizes and degasses it, and recirculates it.  The process continues for between five and ten minutes, depending on the influent concentration and desired resulting effluent.


The WATERCLEAN™ system is scalable, has a small environmental footprint, can be portable and as a result, has a wide range of applications.  We have constructed prototypes for bench and field testing of the Marine WATERCLEAN™, which operates on 12VDC and processes 1,000L per day, and the Residential WATERCLEAN™, which operates on 220VAC and processes 3,000L per day.  The Marine WATERCLEAN™ is suitable for livaboard boats where it will process both the grey water and the blackwater with safe discharge to the water outside of the boat.  The Residential WATERCLEAN™ is suitable for both wastewater treatment with discharge and wastewater treatment with re-use and re-circulation.

There are many other applications including:

  1. Recreational vehicles - legal discharge to municipal storm sewer system
  2. Reptage pretreatment - legal discharge to municipal sanitary sewer system
  3. Leachate pretreatment - legal discharge to municipal sanitary sewer system
  4. Medical waste pretreatment - legal discharge to municipal sanitary sewer system
  5. Restaurant waste pretreatment - legal discharge to municipal sanitary sewer system
  6. Commercial shipping ballast water residual treatment
  7. Disinfection of invasive species prior to discharge to fresh water

The WATERCLEAN™ Machine disinfects pathogens, reduces nutrients (carbon, phosphorus, and nitrogen), mineralizes volatile organic compounds, and transforms pharmaceuticals & personal care products.  No other onsite wastewater treatment system can achieve these results.

The WATERCLEAN™ Machine is faster, better, and has a smaller environmental footprint than any onsite wastewater treatment system on earth.  As well, the Residential WATERCLEAN™ Machine complies with the performance requirements of the National Sanitation Foundation (NSF), the Bureau de normalisation du Québec (BNQ), and Environment Canada – Canada ETV.


The Trademark and Patents (U.S. and Canada)

The WATERCLEAN™ trademark is a registered trademark for Canada that is the property of Great Lakes Clean Water - Limited Partnership.


The two Canada patents and four United States patents issued have been assigned to Great Lakes Clean Water - Limited Partnership.  The four Canada patents and two United States patents that have been applied for will be assigned to Great Lakes Clean Water - Limited Partnership.


The quality of the patents both issued and applied is very important for the assessment of their value.  While narrow focused patents are relatively easy to achieve, they are of little value.  Alternatively, broad unfocused patents are difficult to achieve and can be of great value.  We have achieved the latter.  Our patents are comprehensive to the extent that others desiring to accomplish OWT using AOP have been suitably frustrated.  We are continuing our investigations into, and improvements to, the WATERCLEAN™ technology at the Centre for Alternative Wastewater Treatment in Lindsay Ontario, and new patent applications will continue.
