An apparatus for carrying out the process comprises a housing in which two separate chambers are provided. Each chamber has separate inlet and outlet ducts. The inlet ducts are connected to separate feeding devices for liquids. Separate regulating devices are arranged for regulating the flow through each of said two chambers and means are provided for regulating the pressure differential between the two chambers.
