Water is humanity's most vital natural resource. Water fuels economies, societies, and life itself. Due to population growth and continued industrialization, there is not enough clean, useable water on earth to satisfy demand.
Maintain high quality water standards in our rivers, lakes, and aquifers is vital to our future. Clearas Water Recovery cleans water sustainably for industrial, municipal, and agricultural customers.
Clearas Water Recovery technology recovers excess nutrients from industrial, municipal, and agricultural wastewater. The high-quality water produced may be safely discharged into rivers, lakes, and streams, or reused in plant operations.
The Clearas System is a bolt-on system that seamlessly integrates with existing water treatment facilities. The Clearas System can meet or exceed a variety of water quality needs.
Clearas Water Recovery Process: Cleaning Water, Sustainably
In the blend phase, contaminated wastewater and CO2 are mixed in a turbulent environment with a proprietary blend of algae and other biological organisms to initiate the recovery of harmful nutrients.
In the Nutrient Recovery Phase, a bio-diverse mixture flow travels through the vertical pond system that optimizes biological activity and photosynthesis to stimulate the recovery of phosphorus, nitrogen, and other contaminants. The process consumes nutrients and CO2 while producing clean water and pure oxygen. The recovery phase operates in continuous mode, is self-cleaning, and produces zero waste.
In the Separation Phase, advanced microfiltration separates the bio-diverse mixture into two streams—a clean water stream and a recycle stream. The recycle stream supplies healthy algae and biological organisms to reseed new wastewater entering the Blend Phase. Surplus algae and biological organisms are removed from the treatment process to keep the ratio of biomass to food balanced. The waste biomass is harvested, dried, and processed. It can be disposed of naturally or used for a variety of purposes. The Clearas treatment process has been shown to reduce phosphorus by a factor of 10X and nitrogen by a factor of 3X. The Clean Water Stream is now free of harmful levels of contaminants. It can be safely discharged into a nearby body of water, or sent back for reuse in upstream plant operations.
Water remediation using algae is an exciting technology that couples a critical need with a natural process that yields a valuable product. Clearas Water Recovery has taken an innovative approach to this need and developed robust technology that is able to remove harmful phosphates and other chemical contaminants from waste water from impaired water sources. Clearas Water Recovery continues to develop technologies to improve their water remediation technologies, including improve 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.

I have been associated with the Clearas team for about 24 months. The combination of plant and bacteria biology to recover nutrients in a closed loop reactor has proven to be efficacious and cost effective. No current biological or chemical precipitation/filtration regimen has been able to duplicate the low effluent total phosphorus and total nitrogen that can be produced from the Clearas system. This truly green and sustainable technology can be applied for nutrient recovery across many business segments including aquaculture, agriculture, municipal wastewater and pulp and paper to name only a few. I believe this process is currently the best available technology.

The Clearas Water Recovery system is a breakthrough in water treatment which I believe represents the future for municipal water treatment. With nutrient restrictions continuing to tighten this technology provides a natural and biological extension to our existing infrastructure and our pilot project test results confirm a 7–10X improvement in low level phosphorus achievable. 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.
