Abstract
The wastewater industry is one of largest consumers of energy with an estimated 20% of total global electricity consumption used for treatment of wastewater. It is therefore in the best interest of the environment and economics of STP to conserve it. Electricity conservation is necessary because conserving electricity reduces both its costs and the associated environmental impacts, leading to less pollution and greenhouse effect. The parameters which evaluate the performance of the plant are BOD, COD, TSS. This study is based on incorporating Six Sigma principles and applying them to reduce the variance of these parameters and to have positive impact on the performance. This study identified aeration equipment as the major energy consumer and suggested to apply time management techniques to it. Reducing the aeration time generated savings of 17%. The BOD and COD levels were also found out to be within the permissible limit by applying time management to the blowers. It is found that the blower had been hackneyed and needs to be optimized for conserving the energy of the STP plant at ADYPU College.
