The AquaNereda® Aerobic Granular Sludge System is an innovative biological wastewater treatment technology that provides advanced treatment using the unique features of aerobic granular biomass. An aerobic granular biomass is comprised of compact granules, which are a layered microbial community that provides superb settling properties. Within a single tank, the system creates proper conditions to develop and reliably maintain a stable granule, without a supplemental carrier. The granule layered aerobic and anaerobic zones allow for simultaneous processes to take place in the granular biomass, including enhanced biological phosphorus reduction, and simultaneous nitrification and denitrification. The unique process features of the AquaNereda system translate into a flexible and compact process that offers energy efficiency and significantly lower chemical consumption.
