treating municipal wastewater

This chapter describes the systems used to treat municipal wastewater subject to diverse local constraints and with a view to obtaining the qualities required to allow discharge (per local standards) or even re-use, including the most stringent demands (see indirect re-use as drinking water or as ultra pure water).

The reader is advised to refer to chapters fundamental physical-chemical engineering processes applicable to water treatment and fundamental biological engineering processes applicable to water treatment for a description of the fundamentals relating to the physical-chemical and biological treatment processes applied, as well as to chapters pre-treatments, flocculators – settling tanks – flotation units, biological processes, methane fermentation, filters, using ion exchangers and separation by membranes for a description of the degremont® technologies (pre-treatment, settling tanks, filters, biological systems, membranes) included in the treatment trains described in this chapter.
