Zusammenfassung:	Two processes are used to treat sludge and/or waste water with a dehydration of the sludge and/or sewage water in the first stage and a regeneration of the sludge water in the second. The first process stage has a flocking action to gather fine sludge particles in the sludge and/or industrial water waste, to be sepd. into solid and fluid components. The fluid is passed through a filtering and water cleaning action while the solids are diverted to a treatment process. In the regeneration stage, for sludge water with a high specific gravity contg. sludge particles from a hydromechanical digging action, the sludge water is collected from the digging to be sepd. into solid and fluid components for the separated water to be reused while the solids are removed for processing.
