Pretreatment by means of microsieving
Pretreatment by microsieving is an essential step towards energy-efficient wastewater treatment. The process is based on our Noggerath® Drum Screen RSH-MG, which enables the separation of solids through fine screening of raw wastewater.
The Passavant® CarbonExtract® process is an attractive alternative to conventional preclarification. It offers significantly smaller dimensions and an optional flocculation unit that allows for a considerably increased extraction of carbon. The highly organic screenings can be used in anaerobic sludge stabilization (digestion) to produce biogas or through combustion/gasification technologies.
