The WPL Lamella Separator is designed to maximise efficiency in settling out solids in sewage and industrial wastewater. It can achieve high throughput in a minimal site footprint – some 90% smaller than traditional separators and clarifiers.

This highly efficient treatment process removes up to 95% turbidity, suspended solids and associated pollutants. The precision hydraulic design of the WPL Lamella Separator ensures even flow distribution over the inclined plates to enhance solids separation.

Discharge occurs through a full-length v-notch channel positioned on either side of the lamella separator. This weir design significantly reduces the velocity of the effluent flow resulting in a smaller quantity of suspended solids being transported to the outfall point.

Why choose a WPL Lamella Separator


  • Occupies 90% less space than traditional settling equipment


  • High treatment efficiency – removes up to 95% turbidity, suspended solids and associated pollutants

Minimal operation and maintenance

  • No moving parts within the clarifier reducing risk of downtime
  • Option of an automatic sludge removal system to reduce operator time
  • Option of an human-machine interface (HMI) for greater efficiency, improved reliability and ease-of-maintenance

Reduced installation cost

  • Supplied as complete units manufactured off-site
  • Quick set-up due to pre-configured weirs and fixed pipework
  • Units can be linked in series or in parallel
  • Compact and lightweight for ease of transportation and flexible installation


  • Painted mild steel as standard
  • Stainless steel grades available

Pilot trials and sedimentation tests

WPL can provide a pilot unit to conduct onsite tests that will identify the precise equipment required for your operation.

We offer simple sedimentation tests onsite or at our in-house laboratory. This makes it possible to verify settling capability of the system and the chemical dosing rates or polyelectrolytes required to optimise effluent quality and settling rate.
