Accurate air flow regulation for aeration tasks in wastewater treatment plants The accurate regulation of the air flow for aeration basins ensures best process quality and also helps save money as energy-intensive compressed air is applied to the basin at an optimised rate. Germany for contaminated, aggressive and condensing waste gases, and can thus easily handle your air. You are thus benefiting from excellent stability in long-time use and drift-free measurement, while maintenance is kept to a minimum. This ensures that your regulating system works properly and accurately even after many years....

reduced. This results in high accuracy, even under unfavourable inlet conditions. Our design does away with costly slide valves that are prone to malfunction. The flapper valve works also with contaminated air and ensures unobstructed passage of particles and condensates. With a flapper valve, "flooding" is not possible. The high-precision regulation actuator also supplies the connected differential pressure transmitter and features a built-in intelligent regulator. There is thus no need for an external regulator with separate wiring. The deltaflow dynamic pressure probe is in use in thousands...
