AquaNereda by Aqua-Aerobic Systems

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.

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.

Key Features and Benefits

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.

AquaNereda by Aqua-Aerobic Systems was developed by Royal HaskoningDHV.
