CLEARAS Water Recovery, Inc. specializes in biological-based water treatment technologies aimed at nutrient recovery from industrial water discharge and wastewater. Its primary offering, the Advanced Biological Nutrient Recovery System (ABNR), utilizes microbiology—specifically microalgae and other biological organisms—to effectively recover excess nitrogen, phosphorus, and other contaminants. This innovative system operates in a controlled, continuous flow environment, optimizing performance by managing retention time, nutrient load, and biological mass. The process is entirely renewable and results in a plant-based biomaterial co-product, which can be repurposed for various applications, including plastics, foams, animal feeds, and soil enhancements. CLEARAS serves both municipal and industrial point source dischargers and is headquartered in Missoula, Montana. The company, originally founded in 2008 as AlgEvolve Inc., rebranded to CLEARAS Water Recovery, Inc. in July 2013.
