ABSTRACT:
A wastewater aeration system in which the volume of wastewater is divided into a plurality of different zones which are aerated sequentially one at a time with the full capacity of the blower supply sized for oxygenation needs. In the case where the oxygenation needs ar significant, the number is obtained by dividing the aeration rate required for mixing by the aeration rate required for oxygenation and rounding upwardly to the nearest integer. The blower capacity should continuously deliver the oxygenation rate to assure adequate aeration for both oxygenation and mixing while minimizing energy consumption. The air supply pipe network includes a header supply pipe for each zone and a valve for each header supply pipe which is automatically controlled by a programmable programmer. In the case where mixing only is required, the number of zones is limited by practicalities in order to prevent undue settling.
