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).

Towards energy positive wastewater treatment plants ...

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 Neutral and More - Energy Reduction and ...

This new outlook towards wastewater treatment opens up its hidden potential. It is discovered that wastewater is not a waste to get rid of, but a valuable source from where various resources and energy can be recovered. With this new finding, the target of the treatment plants is now to be energy neutral and if possible energy positive.
