Conditions of Joint Treatment of Municipal and Industrial Waste Water (Example from
France)
The general case in the chemical industry in France is that effluents are treated on-site. Joint
municipal and industrial waste water treatment, however, is sometimes encountered, e.g. in biochemical
productions (such as vitamins or antibiotics via biochemical pathways), and in formulation
and conditioning activities for which the flow rate and the load of the effluent remain
manageable by a municipal treatment plant. In this case, a study of the impact of industrial
streams on the municipal treatment plant (impact on operation and sludge disposal) is done and
an “industrial release agreement” is signed between industry and the local waste water management
authority.
A Municipal Decree is issued that generally contains the following main provisions of the
agreement:
� pH of the effluent comprised between 5.5 and 8.5 (eventually 9.5)
� temperature of the effluent
