Physico-Chemical Treatment

Flocculation Unit Physical treatment technologies refer to the processes which are designed to separate and concentrate various components of site contaminants without chemically altering the form of these components. Sedimentation is an example of this process.

Chemical treatment, such as oxidation, refers to a process which brings about a chemical transformation of one or more components of contaminants as the primary means of either removing a particular component or reducing its toxicity.

Physico-chemical treatment methods integrate both physical and chemical processes as the major features of the technologies.

The in-situ and ex-situ technologies are described below.
