The AquaNereda aerobic granular sludge technology is an innovative biological wastewater treatment system that provides advanced treatment using the unique features of aerobic granular biomass.

The aerobic granular biomass is composed of compact granules which consist of layered microbial communities and provides superior settling compared to conventional activated sludge. Within a single tank, the process creates proper conditions to develop and reliably maintain a stable granule population without the need for a supplemental carrier. The layered aerobic and anaerobic zones within the granule 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 technology translate into a flexible and compact process that offers energy efficiency and significantly lower chemical consumption culminating in a low life-cycle cost.
