Conventional Clarifier Overview:

The WesTech Conventional Segmented Blade Clarifier is a capable option for smaller primary clarification applications. Each Conventional Segmented Blade Clarifier can be upgraded with several WesTech COP™ Clarifer Design features.

The WesTech COP™ Clarifier is the result of research and design focus on building a better clarifier. Each COP Clarifier 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 key design parameters to optimize the physical forces and limitations occurring in any clarifier to achieve superior performance:

1. Scum Removal: Removes scum buildup from within the feedwell and from the clarifier surface.

2. Basin Configuration: Uses deeper side water depth (SWD) and proper floor slope design for maximum capacity and highest effluent quality for the least cost.

3. Density Current Baffle: Eliminates wall currents and prevents short-circuiting. The wall-mounted baffle is low in cost and requires no maintenance.

4. Flocculating Feedwell: Promotes hydraulic flocculation in the inlet area and is designed to eliminate scouring of the sludge blanket.

5. Energy Dissipating Inlet (EDI): Converts the high energy feed from the center column into a lower velocity flow that is gently mixed in an impinged or tangential flow into the flocculating feedwell to maximize flocculation.

5. Energy Dissipating Inlet (EDI): Converts the high energy feed from the center column into a lower velocity flow that is gently mixed in an impinged or tangential flow into the flocculating feedwell to maximize flocculation.

6. Center Column: Minimizes floc shearing and reduces influent energy.

WesTech Segmented Blade Clarifiers are designed to address clarification requirements where a spiral blade is not required for sludge transport. Rake arms are made up of several straight segments, usually set at 30 - 45° attack angle. Settled solids are transported through one blade width with each passing of a rake arm.


Features

  • Positive means of removing heavier solids
  • Simplicity of design and operation
     

Benefits

  • Low mechanism cost
  • No clogging from orifices or plugging of pipes
  • Usually results in more thickened solids than suction type mechanism

Applications

  • Primary clarification
  • Secondary clarification
