Task of the SLUDGE PRESS and the PRESS-BAND-FILTER is to remove the sludge, which is arising during the process. The supply happens with compressed air by means of membrane pumps. The filter-medium holds the sludge back (pressed sludge) and the clean liquid will be drained back to the tank.
The oil separator ensures the separation of the oil in the degreasing chemical. The cleaned bath medium will be drained back to the tank by means of pumps.
