Lamella EcoFlow® Inclined Plate Settler

20180417_091509 - Signal Butte Mesa AZ

The Lamella® is the original inclined plate gravity settler. Introduced by Parkson in 1971, it has been the industry standard for this technology.

Inclined plate settling works when a solid/liquid stream that has been flocculated, enters a tank, and flows upward between a pack of inclined plates.  The solids fall to the plate surface, where they slide by gravity down to a sludge collection hopper. The clarified effluent flows through orifice holes and exits the top of the settler.  

The innovative Lamella EcoFlow®, which was unveiled in 2012 and recently granted a patent, eliminates the area of interference at the bottom of the plates and allows for full utilization of the plate settling area.  This translates to a capacity increase of 25% in the same footprint and allows for easy retrofitting to upgrade older installations to the innovative EcoFlow® design!

The Lamella® has been utilized in countless applications, including the following:

  • Potable water clarification
  • Industrial process water
  • Sand filter backwash
  • Metal finishing
  • Mining
  • Groundwater
  • River presedimentation


  • 10 times the equivalent settling area of traditional clarifiers
  • New, patent-approved Lamella EcoFlow® design – no moving parts
  • Corrosion-resistant FRP plates
  • Completely submerged plates
  • Plates installed at 55⁰ for optimal solids settling

Optional Features

  • FRP tank construction for highly corrosive applications
  • Rubber-lined steel construction
  • High temperature plates
  • Rapid mixing and flocculation packages
  • Sludge storage and thickening package
  • Chemical dosing equipment


  • Lamella EcoFlow® allows for a 25% increase in capacity over the standard design
  • Flexible design allows for custom applications to be tackled
  • Self-cleaning plates and no moving parts translate to low maintenance costs
  • Space-saving footprint allows for efficient use of land
