Abstract (en)

[origin: WO03076355A1] The invention relates to a method for the thermal treatment of aqueous concentrates, in particular from concentrated aqueous discharges and aqueous wastes from waste processing units and industrial production or purification processes. According to the invention, the aqueous concentrates are used to regulate the flame temperature in the high temperature firing for an industrial production process, for example in the production of clinker cement. The inorganic residues are thus chemically or physically incorporated in the product of the industrial production process.
