Process and equipment, in particular for the conditioning of waste water sludges

摘要

It is intended to simplify and make easier cavitation treatment in a process and equipment for treatment of liquid/solids mixtures, in particular for conditioning of suspended solids by means of cavitation. In the process, this is achieved by means of the fact that the material mixture to be treated is withdrawn from a high-level reservoir, passed through at least one pipe bend and then to a drop-pipe in such a way that a cavitation zone forms in the flow at least in areas upstream, within and downstream of the pipe bend and in terms of equipment by means of the fact that the equipment consists of a high-level reservoir (1), an outlet nozzle (2) preferably in a horizontal position, at least one pipe bend (3) connected to the outlet nozzle (2), and a drop-pipe (4) and a control valve (5) in the vicinity of the end of the drop-pipe.
