Enviroquip SymBio® Elite process (protected by US Patent # 6,712,970) as a cost-effective option for biological nutrient removal (BNR) needs. Based on Enviroquip’s original, award winning, SymBio® process for simultaneous nitrification and denitrification, the SymBio® Elite process is a technological advancement in the area of BNR and wastewater treatment process control. The SymBio® Elite process is capable of providing a single-step nitrogen and phosphorous removal for wastewater treatment plant operators.

With the Enviroquip SymBio® Elite process, the process control strategy is modified to allow the development of a partial anaerobic environment in the sludge floc by lowering the operating DO levels while monitoring the biomass NADH levels. This results in phosphorous release by the biomass in the anaerobic zone. Enhanced biological phosphorous uptake occurs in the aerobic zone of the floc or when the aeration is subsequently increased by the SymBio® Elite process control system. Municipal as well as industrial plants (existing as well as new) can address their BNR needs in one step with the SymBio® Elite technology. A second step, known as the post-aeration or the post-nitrification step can be added (optional) to improve the overall plant performance and to provide positive DO in the mixed liquor before discharging to the secondary clarifiers.
