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.

The process facilitates energy efficiency and achieves results at the lowest chemical and electrical energy inputs possible.

• 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
