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 ...

Feb 01, 2016  1. Introduction. The carbon source in wastewater contains large amounts of chemical energy. Maximizing energy recovery from wastewater to achieve energy-neutral or -positive wastewater treatment has been the target of global water utilities and is an essential element for sustainable wastewater management (Kartal et al., 2010, Van Loosdrecht and Brdjanovic, 2014).

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.

Towards energy positive and carbon neutral wastewater ...

The way we treat our wastewater has not changed in the past 100 years. Conventional wastewater treatment plants make inefficient use of energy and carbon resources, promoting GHG emissions and bearing a toll on our ever-growing human population. Wastewater treatment relies on the biological removal of organic carbon and reactive nitrogen.
