The AquaNereda aerobic granular sludge system from Aqua-Aerobic Systems replicates the same effluent quality as a well-designed enhanced biological nutrient removal facility but without the use of chemicals. The technology, owned by Royal HaskoningDHV, dramatically reduces the footprint and energy requirements to provide a competitive alternative for high-performance plants. A full-scale system at the Rock River Water Reclamation District in Rockford, Illinois, demonstrates the technology and is a part of the company’s technical seminar program. The facility will help accelerate the implementation of aerobic granular sludge technology in North America. 815-654-2501; www.aquanereda.com; Booth 6625.
