Product Overview

CM Aquatechnik supplies full-bridge and half-bridge sludge scrapers for circular and rectangular final clarifiers and primary settling tanks. Scrapers continuously collect settled sludge to the central hopper (circular) or sludge trough (rectangular) for return or waste sludge removal. Surface scum skimmers remove floating material simultaneously.

Key Features

  • Continuous operation ensures consistent sludge blanket depth control
  • Overload torque cut-out prevents mechanical damage from thick sludge
  • Surface scum skimmer removes floating FOG and scum simultaneously
  • Stainless steel 316L flights and wear shoes for long service life
  • Low peripheral speed (2 m/min) minimises sludge disturbance
  • Modular construction simplifies on-site assembly in large clarifiers

Applications

Municipal secondary clarifiers Industrial primary settling tanks DAF float sludge collection Sludge thickening tanks Drinking water sedimentation basins Potable water treatment
