Tank aeration system

The longer untreated sewage or black water are stored in holding tanks, the more likely it is for anaerobic conditions to develop. Natural biological processes within the sewage consume oxygen and this consumption needs to be compensated. A tank aeration systems compensates the oxygen consumption by the supply of fresh oxygen and thereby also assists the active biological processes – the natural way of sewage treatment. It also helps to minimize sedimentation of solid particles, although not as effectively
