Towards greater energy autonomy of wastewater treatment plants?

Abstract

This note is a point on the issue of energy in wastewater treatment plants. The questions of minimizing energy consumption and of promoting the renewable energy from the treatment of wastewater are discussed, highlighting the advantages and limitations of different technical solutions available. An example of hedging a part of the energy needs from some renewable energy produced on site is given (case of the Seine-Aval WWTP)
