Aeration control in live operation: references from running plants
Treatment plants in regular and pilot operation – with results from live operation
Treatment plants running the adaptive map controller
The adaptive map controller is in use at municipal wastewater treatment plants in Lower Saxony and Bremen. The overview shows which plants run it in regular operation and which are currently in supervised pilot operation.
In regular operation 5 plants
In pilot operation 3 plants
-
WWTP Verden
-
WWTP Hannover

WWTP Delmenhorst
Two of the plants are documented in detail. The results come from live plant operation. The adaptive map controller only supplies the dissolved oxygen setpoint; the existing underlying control continues to run unchanged. How commissioning within one to two days works is described separately.
WWTP Oldenburg (OOWV)
The Oldenburg WWTP is one of the largest wastewater treatment plants in Lower Saxony with 4 parallel activated sludge basins. The plant was already among the top 10% in Germany before the map controller was deployed.
Despite interim changes (new compressor, faulty ammonium measurement), the map controller independently adapted to the new conditions. No readjustment was required.
WWTP Seehausen (hanseWasser Bremen)
The Seehausen WWTP is one of the largest wastewater treatment plants in Germany with 6 parallel activated sludge basins. Due to the plant design, the amc could be directly compared with conventional oxygen setpoint control.
During combined sewer events, the oxygen setpoint was raised early, enriching the activated sludge basin with oxygen. This reduced the ammonium peak by 40–50% compared to the reference basin.
