The AquaNereda aerobic granular sludge system from Aqua-Aerobic replicates the same effluent quality as an enhanced BNR facility, but without the use of chemicals. The reduced footprint and low energy requirement of the AquaNereda process provides an alternative for high-performance plants. The biological treatment technology purifies water based on bacteria growing the compact granules. 800/940-5008; www.aqua-aerobic.com
