Compressed air aeration stations

These days, longer and longer distances must be covered to treatment plants with minimal waste water quantities. Hydrogen sulfide forms in the pressure pipe which leads to the development of sulphuric acid, causing corrosion to metal and concrete materials as well as bad odours.

The compressed air aeration stations from hoelschertechnic-gorator® aerate the waste water where dwell times in the pressure pipe are too long in order to delay the onset of anaerobic conditions and prevent the formation of a sewage film and sulphuric acid.

hoelschertechnic-gorator® designs plants according to the conditions present and delivers turnkey pumping stations with consideration to the customer’s requirements. As a manufacturer and plant builder, hoelschertechnic-gorator® is also able to develop special solutions for customers.
