HAMANN CS AirFlow
Tank aeration & circulation system
Tank aeration and circulation systems combine our aeration technology with a circulation of the tank content to achieve maximum conditioning performance. Besides keeping the sewage in aerobic condition (no risk of hydrogen sulphide (H2S) or sulphuric acid (H2SO4) formation, support of natural biological processes), these systems also effectively prevent sedimentation. When tank contents develop sediments, the suspended solids concentrate in the lower layers and the dissolved solids in the upper layers.

Sewage sludge circulation system
Sewage sludge stored in a holding tank tends to rapidly develop sedimentation. The lower layers will then no longer be pumpable for discharge purposes and have to be manually removed from the tank, requiring a considerable amount of time and effort. To avoid having to execute this most unpleasant task, a circulation system should be installed in all sludge tanks. It constantly circulates the sludge in the holding tank, keeping it in pumpable condition at all times.

Grease Separator
Grease separators are crucial for the performance of sewage systems. Fats, oils and grease, in short: F.O.G., have a negative impact on the performance of the sewage system. Pipelines and sensors are blocked or sealed by grease deposits within a short time. In holding tanks, grease accelerates the formation of hydrogen sulphide, a toxic and highly odorous gas. Hydrogen sulphide can lead to the formation of sulphuric acid, which then attacks the substance in the pipes. In addition, the purification performan
