High Precision in the Aeration Basin

Using WAGO technology, H2Ortner from Passau developed a controller module that gives operators of wastewater treatment plants need-based control of the blowers in their aeration tanks determined by the degree of contamination in the wastewater. This type of control saves electricity, lowers the nitrogen concentration in the discharge and increases operational reliability. Practical experience shows that in many cases, plant operators can recoup the investment through the waiver of the wastewater charge alone.
In any modern wastewater treatment plant, there are team members who work around the clock without vacation time or even payment: bacteria that break down harmful substances in the wastewater in the aeration tank. All the microorganisms that are responsible for nitrification – the conversion of nitrogenous ammonia into nitrate – need for their work is oxygen.

Advantages of the WAGO PFC200 Controller:

  • The controller allows Web-based control and parameterization of the processes.
  • The clearly organized interface allows all the data to be grasped quickly.
  • The comprehensive interfaces provide the optimal conditions for communication with various controllers.
