The WesTech COP™ Clarifier is the result of research and design focus on building a better clarifier. Since it's introduction in 1989, the COP Clarifier has gained wide acceptance, and installations now number in the thousands. While key design features have now become imitated with some success by many manufacturers, the WesTech COP is the only clarifier with a process guarantee. Each COP is designed for the specific process requirements of each plant. Proprietary algorithmic computer programs are utilized and further refined to result in a clarifier that provides high performance, and is of benefit to plant operations overall.  An acronym for Clarifier Optimization Package,  this highly efficient clarifier design utilizes nine key design parameters to optimize the physical forces and limitations occurring in any clarifier to achieve superior performance.

1. Basin configuration: uses optimum side water depth and floor slope for maximum capacity and highest effluent.
2. Center column: minimizes floc shearing and reduces energy level.
3. Energy dissipating inlet: converts the high energy feed from the center column into low velocity, hydraulic mixing energy in the flocculating feedwell.
4. Flocculating feedwell: maintains the tangential motion imparted by the EDI to promote hydraulic flocculation in the inlet area and is designed to preclude scouring of the sludge blanket.
5. Effluent weir baffling: eliminates wall currents and prevents short-circuiting. Wall-mounted baffle is low in cost and easy to maintain.
6. Customized spiral rake blades: increases sludge transport capacity 300-500% and lowers sludge blankets while maintaining higher underflow concentrations.
7. Sludge withdrawal: eliminates short-circuiting of influent to underflow with a uniquely designed hopper or sludge ring.
8. Scum removal: reduces nuisance scum build-up within the feedwell and clarifier surface.   

BENEFITS: 
 •  Optimizes the clarification process
  
 •  Results in higher settled solids concentrations in the underflow and lower solids
     concentrations in the effluent 
 
 •  Improves performance of downstream processes

 •  Sludge inventory is maintained near the center of the clarifier, not under the weir, 
    resulting in lower torques and less effluent suspended solids
     
 •  Eliminates rat-holing
 •  Rapid sludge removal
 •  Sludge transport and feed flow velocities are integrated
 •  Reduces denitrification flotation
 •  No clogging problems associated with other rapid sludge removal types
 •  Wide rages of operational applications
 •  Simplicity of design and operation
 •  Not affected by location of settle sludge
