Sludge Management

Sludge processing represents an important step in the wastewater treatment process. At present, there are two equipment types or in a better way – two possibilities of sludge processing. The first one is the so called “spiral dehydrator”, i.e. the equipment used for sludge thickening and subsequent dewatering. The second possibility is the process of Aerobic Thermophilic Stabilization (ATS), in other words the “sludge stabilisation process”, during which bacteria and viruses are wiped out and a valuable fertiliser prepared out of the sludge.
