Lamella Thickeners

The lamella principle uses several parallel inclined plates to create the maximum settling area possible given the space restrictions.

Conventional clarification equipment requires a much larger surface footprint in order to match the solids removal capacity of a lamella clarifier. Loading rates normally used for the design of conventional settlers can be applied to the sizing of a Lamella clarifier/settler by substituting the single-surface settling area of a conventional clarifier with the multi-surface settling are of a Lamella Plate.

The casing is typically made of coated or stainless steel and the lamellas are made of propylene. The effluent enters the lamella separator through the inlet channel on the top and flows to the bottom of the separator. The water is led back to the top, on its way the water flows through the lamellas, onto which the solid particles settle. The purified water flows to the top and reaches the outlet by passing a weir. The sludge slides down the lamellas and is collected in the sludge funnel. A rabble rake can be installed to prevent caking of the sludge. The sludge is discharged at intervals when the required density is achieved. Our Lamella Separators are manufactured in a wide range of sizes to suit all applications.

Features & Benefits:

  • Multi-surface settling area.
  • The compact design enables high thickening capacity relative to footprint.
  • Easy and affordable maintenance as there are few moving parts.
  • Balanced flow distribution ensures equal flow to each plate and across the plate surface area.
  • One piece construction reduces installation time and lowers installation costs
  • Available in a range of sizes to suit a variety of installations. 3000m3/hr.
