Added efficiency to wastewater nutrient recovery


ThermoEnergy has introduced Thermo ARP, a high-efficiency process for recovering nutrients from wastewater. The process is designed for use with agricultural, industrial and municipal anaerobic digesters where the wastewater stream may require a simpler treatment strategy for ammonia removal. 

The addition of the new Thermo ARP to the existing ARP system which is currently being installed at New York City's 26th Ward wastewater treatment plant enables ThermoEnergy Corporation to address a wide range of ammonia reduction issues across multiple market segments.

According to Mr. Cary Bullock, CEO of ThermoEnergy Corp., the mechanism for ammonia recovery is completely different from our ARP system and takes advantage of conditions typically found in industrial, food, and agricultural treatment sites, as well as at some municipal treatment sites. At these sites, Thermo ARP eliminates chemical pre-treatment while reducing the cost of nutrient removal by as much as 70% compared to the traditional ARP system.

Both ARP and Thermo ARP have the economic and environmental advantage of recovering nitrogen as a fertiliser. By recovering ammonia and not releasing it into the atmosphere, revenue from the sale of fertilizer combined with the nutrient credits now offered in several states, can provide less than a three-year payback on the equipment investment.
