the aeration tank can allow for the growth of problematic bacteria Very few problems are associated with the aeration tank as long as the aerator remains operational. In municipal and industrial wastewater treatment, aeration is part of the stage known as the secondary treatment process. The activated sludge process is the most common option in secondary treatment. Aeration in an activated sludge process is based on pumping air into a tank, which promotes the microbial growth in the wastewater. The microbes feed on the organic material, forming flocks which

For tougher applications such as sludge or industrial wastewaters, coarse bubble is often the best solution. This includes aerobic sludge digestion, sludge storage, flow equalization, channel aeration, grit, wastewater treatment process which speeds up waste decomposition. Activated sludge is added to wastewater, and the mixture is aerat- ed and agitated. After a certain amount of time, the activated sludge is allowed to settle out by sedimentation and is disposed of (wasted) or reused (returned to the aeration tank) Aerobic – a condition where oxygen is present BOD – biological oxygen demand.
