4. Costs of chemical and physico-chemical treatment techniques for industrial water

Information on the cost of treatment techniques varies widely, depending on the scope of the calculation.

Thus, for this section, we will base the information presented on the study carried out by IRH Ingénieur conseil on behalf of the Rhône Méditerranée Corse water agency in September 2010. These data must therefore be analyzed in relation to the defined scope of work.

It should be noted that, as the costs correspond to a preliminary design approach, they do not take into account supplies and works for utilities and infrastructure such as roads, fences and landscaping.

Some examples of costs are shown in table 23 . For further details, please refer to the original document.
