        Phenols, S, and NH₃ are recovered from the effluents at hydrogenation works using the I. G. Farbenindustrie A.-G. process.  The slightly acidic effluents from Fischer-Tropsch synthetic petrol works are treated by biomechanical methods.  The strongly acidic effluent from synthetic fatty acid works is made harmless by separating the crude paraffin wax and neutralizing.
