Bateman Westech Thickeners are used for many industrial sedimentation and filtration applications. The thickeners are precision engineered and manufactured to rigid standards, providing superior mechanical and operational performance.

The range includes conventional and high-rate thickeners and clarifiers. These machines are fitted with unique drive mechanisms, complete with lift capabilities and Torkmatic units to provide superior performance.

The drives of Bateman Westech thickeners are available in a wide range of sizes up to, but not limited to, 90m. They can be retrofitted to almost all existing thickeners to upgrade performance and extend service lives.

Bateman Westech Thickeners offer many advantages

• The feed is evenly dispersed to ensure an adequate contact time with the flocculant, resulting in the most effective settling of the solids and avoiding short-circuiting.
• The desired process velocities are attained, with feed wells sized to yield.
• Operating lives are long and maintenance requirements low.
• Protection against overloads is provided by Torkmatic units which manage and indicate the torque loadings.
• The drives can handle shock loads, uplifting loads and large overturning moments without damage.
• All components of the drives are coupled - no need for chain or belt drive transmissions.

High-rate thickeners

Bateman Westech HiFlo Thickeners separate liquid and solids at very high rates because the hydraulic rates of the systems can be 10 to 20 times greater than those in conventional thickeners.

• Innovative design greatly reduces the plant area required for a HiFlo thickener.
  
  
  • Substantially reduced capital and installation costs, when compared with conventional thickening units sized for the same production requirements.
    
    
• Bateman Westech 's design provides superior system performance
  
  
  • Deaeration of the thickener feed prior to flowing into the feedwell.
  • Proper levels of flocculation, which can be carefully controlled.
  • Feedwell design enhances solid-liquid separation.
  • Pulp-bed-interface sensors maximise performance.
  • Appropriate drive torque provides efficient operation.
    
    
• Bateman Westech drives with lifting capability and high torque capacity contribute to the superior performance.
  
  
• On-site programmable logic control (PLC) systems can utilise the HiFlo sensor outputs to automate control.
  
  
  • Flocculation, pulp level, underflow density, overflow quality, torque and rake-lift positions can all be managed.
    
    
• HiFlo sensor outputs are used in many installations by a distributed-control system (DCS) to integrate the thickener control with other plant functions, resulting in improved clarification of the overflow and a high concentration of solids in the underflow.
