A lamella clarifier is a brand of inclined plate clarifier used in a water treatment process that features a rack of inclined metal plates, which cause flocculated material to precipitate from waterthat flows across the plates.

 

Inclined plate settlers, which include the lamella brand, are primarily used in the water and wastewater treatment industries to separate solids from liquids in effluent streams. The clarifier is the third step in what is usually a four step process for water and wastewater treatment. In wastewater treatment the four main steps are collection and homogenization of effluent, pH adjustment, clarification, and sludge dewatering.

 

Conventional clarification equipment requires a much larger surface footprint in order to match the solids removal capacity of an inclined plate clarifier. This is accomplished because the effective gravity settling area of the inclined plate design is proportional to the total surface area of the inclined plate rack. Loading rates normally used for the design of conventional settlers can be applied to the sizing of an inclined plate clarifier/settler by substituting projected area for the surface settling area of a conventional clarifier.

 

The compact design essentially eliminates any hydraulic disturbances caused by wind or temperature changes that may be problematic with conventional clarifiers located outdoors. Balanced flow distribution ensures equal flow to each plate and across the plate surface area, preventing short-circuiting. Units and plate packs arrive at the job site factory assembled which reduces installation time and lowers installed costs. Minimal moving parts means low maintenance costs.
