The main features of the Marcoule radioactive effluents are given, and it is concluded that even with the low mean specific activity discharge cannot be made to the Rhone without previous treatment. The detailed examination of the characteristics of the effluents, in particular their considerable inactive dissolved product content, the search for maximum elasticity in operation, and the small amount of time available to study and develop new processes on an industrial scale, led to the choice of a processing methed using coprecipitation and chemical coagulation. Coagulation takes place in the presence of lime at a pH of about 11.5. (W.D.M.)
