AquaNereda by Aqua-Aerobic SystemsMike Gillespie
AquaNereda by Aqua-Aerobic System is an advanced biological wastewater treatment technology providing Enhanced Nutrient Removal (ENR) with Total Nitrogen <3mg/L and Total Phosphorus <1mg/L without chemicals. The technology has been used successfully for more than 15 years in full-scale wastewater treatment facilities, with over 80 installations worldwide. It was developed by the Dutch company Royal HaskoningDHV in collaboration with the Delft University of Technology.
AquaNereda is an aerobic granular sludge process that generates durable granules composed entirely of biomass that are very efficient at performing both nitrification and denitrification, while also biologically reducing phosphorus to low levels without chemical addition. One of the main attributes of aerobic granular sludge is its rapid settling properties. Based on the density of the granules, granular biomass settles significantly faster than traditional activated sludge.
The Nereda process has several advantages over traditional wastewater treatment technologies. It uses less energy and chemicals, produces less sludge, and has a smaller carbon footprint. It also has a higher treatment capacity and can be used for a wide range of wastewater types, including municipal and industrial wastewater.

In North America, a major success was the startup of the Wolf Creek WWTP in Foley, Alabama. The three-reactor plant treats domestic wastewater and has a design capacity of 3.5 million gallons a day (MGD) on average with a 6-MGD peak. Within 30 days, the plant was meeting stringent effluent requirements.
The AquaNereda demonstration facility at the Four Rivers Sanitation Authority in Rockford, IL, is a pilot-scale plant that uses the Nereda technology for wastewater treatment. It was constructed in 2016 as a joint project between the City of Rockford and the University of Illinois at Urbana-Champaign to test the effectiveness of the AquaNereda process in cold weather conditions. The facility has a treatment capacity of 150,000 gallons per day and has been successful in demonstrating the feasibility of the AquaNereda technology in the United States.
