5. Water treatment processes

5.1 Processes

Obtaining water that meets specific specifications and/or regulatory constraints before use or discharge requires the implementation of a number of chemical, physico-chemical, physical and mechanical processes and associated equipment.

The field is very similar to that of chemical plants, which transform matter chemically, biologically or physically, and whose technologies come under the heading of chemical engineering (CE) or process engineering (PE).

Unit operations (reaction, distillation, crystallization, filtration, drying, liquid/liquid extraction, decantation, etc.) are at the heart of the GP, and constitute the technological building blocks (see the Unit Operations document base – Génie de la réaction chimique des...
