Towards energy positive wastewater treatment plants ...

Dec 01, 2017  1. Introduction. It has been estimated that over 20% of the total energy consumption for public utilities by the municipalities is for the operation of wastewater treatment plants (Means, 2004).Conventional treatment of municipal wastewater is indeed an energy intensive process, primarily, due to the need for supplying large quantities of air into the biological process (Shi, 2011, Svedal and ...

Energy requirement for wastewater treatment is of major concern, lately. This is not only due to the increasing cost of electrical energy, but also due to the effects to the carbon footprint of the treatment process. Conventional activated sludge process for municipal wastewater treatment may consume up to 60% of the total plant power requirements for the aeration of the biological tank.

Energy Self-sufficient Wastewater Treatment Plants ...

May 01, 2017  Abstract. Optimization of energy efficiency is important for wastewater treatment plants (WWTPs). Increasing energy costs and concerns about global climate change highlight the need to realize energy self-sufficiency in WWTPs. Energy self-sufficient WWTPs have been studied to reduce operation costs, energy consumption and achieve carbon neutrality.
