WaWaTech - Model AvN™ -Advanced Aeration Control for Wastewater Treatment Optimization
The AvN™ Advanced Aeration Control system is designed to enhance the efficiency and capacity of both new and existing wastewater treatment plants. As biogas production becomes a key focus in water treatment, there is an increased need for effective nitrogen and phosphorus removal, compounded by the necessity to cut down on energy and chemical use. The AvN™ system utilizes an innovative process control philosophy to optimize treatment processes. By applying selective pressures on bacterial populations using advanced instrumentation, automation, and control technologies, the system promotes desired bacterial growth. This results in a more efficient use of resources, minimizing chemical and electrical energy consumption while maximizing treatment outcomes. The system is particularly beneficial for wastewater treatment managers seeking process intensification and greater sustainability in plant operations.Improving the capacity and performance of existing (and new) wastewater treatment (WWTP) plants! That is what we can do with AvN™ Advanced Aeration Control.
WWTP concepts more often are changed to maximising production of biogas. Then – relatively with a lack on carbon – nitrogen and phosphorous removal becomes more challenging. Specially if also the overall consumption of energy and chemicals must be reduced even further.
As result, WWTP managers are exploring opportunities to intensify treatment processes. This is where AvN™ has it’s benefits as an overall process control philosophy promoting intensification. AvN™ advances the controls over the relationships between bacterial populations by utilizing instrumentation, control, and automation. Such approach applies selective pressure to aid in the segregation and promotion of desired types of bacteria.
- More efficient removal of total nitrogen (TN) at the lowest total energy cost possible
- Reduced alkalinity, carbon and energy
- Requires very little to no changes to the existing plant footprint
- Saves 25% oxygen and 40% organic carbon compared to conventional nitrification and denitrification
- Aeration savings
- Redirection of influent organic carbon for energy production through anaerobic digestion
