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.

AS-DEHYDRATOR

The AS-DEHYDRATOR is used for the thickening and subsequent dewatering of sludge. The equipment is small and lightweight and can work in automatic operation with minimal maintenance requirements. The device guarantees the thickening of activated sludge to at least 18% of dry matter, for sludge from municipal WWTPs.
