Markets We Serve
The next generation of nutrient recovery technology for advanced wastewater treatment applications.
Highly scalable to the needs of municipalities, the Clearas’ ABNR system produces zero chemical sludge, making it a cost-competitive treatment at the levels where chemical options begin to fail. Because it achieves levels far below the limits that most municipalities are currently facing, it has proven to be a sustainable, multi-generational solution for municipal discharge permit compliance strategies.
A cost-competitive and sustainable solution for meeting tightening wastewater discharge requirements.
Clearas’ ABNR system can be scaled to fit industrial operations in a variety of industries including pulp and paper, aquaculture, fish hatcheries and preserves, poultry and eggs, and golf courses, and is proven to remove a number of high-profile contaminants. Our team brings experience from a range of industries to help clients solve complex problems and engineer innovative solutions that meet their specific needs.
Every batch that we have run through this plant, the final product has come back with zero detect for any nutrients...with this process, we are not only achieving no detect on phosphorus, it’s taking care of nitrogens, the BODs, the suspended solids, and the trace elements like copper.John Bond , Roberts Public Works Director
With a greater than 90% reduction in phosphorus leaving the facility, this technology has demonstrated the potential to make a significant reduction in the overall phosphorus loading within the western basin of Lake Erie. I look forward to a continued demonstration of this technology and to the potential it can have for the entire Great Lakes Region.Alice Godsey, Director of Public Utilities, Perrysburg, OH
After 25 years of reviewing wastewater technologies I believe this has a great future. It’s modular, scalable, energy efficient and has management and control systems very similar to activated sludge processes.Starr Sullivan, Superintendent, Missoula Wastewater Treatment Facility
We’re faced with some of the most stringent nutrient standards in North America and the Clearas system is the first biological solution we’ve trusted and tested.Doug Krapas, Environmental Engineer, Inland Empire Paper
Clearas continues to develop technologies to improve their water remediation technologies, including improving inorganic carbon transfer to aid in phosphate management and algal growth. Their strategic approach to technology development is unique among others involved in the use of algae and will enhance their ability to deliver optimal results for their customers.David Bayless, Ph.D., P.E., Director, Center for Algal Engineering, State of Ohio Third Frontier Facility
