WesTech Spiral Rake Clarifiers incorporate only the required design features of the full COP™ Clarifier. This supplies a clarifier that is built around the advantages of spiral blade design, and where a full COP™ clarifier is not required. Settled solids are continuously transported toward the center of the tank for removal by means of a spiral curved blade.

BENEFITS:
• Increased sludge transportation, resulting in greater solids thickening

• Moves sludge inventory from the outer portions of the tank to the center, resulting in
  lower solids over the weir   and lower torques

• Reduces rat-holing
• Reduces denitrification flotation
• No clogging problems often associated with other rapid sludge removal clarifiers
• Wide range of operational applications
• Simplicity of design
• Performance is not affected by location of settled sludge
