Aeration of sludge

Sewage sludge is an extremely reactive medium. Extended storage in liquid form, in particular, can lead to unpleasant odour development, which is a nuisance not only for local residents. Aerating the sludge prevents the formation of putrefactive gases and keeps the sludge fresh. Additional treatment of the exhaust air in costly treatment plants is not required.

Existing storage tanks can be retrofitted with FUCHS Centrox aerators with foam induction. They provide aeration and circulation of the sludge while simultaneously limiting foam. Open tanks with fluctuating fill levels can also be equipped with FUCHS aerators. Installation on floats keeps them at the required height at all times.
