Lamella Clarifier

Lamella Clarifier is 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 a Lamella 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 a Lamella clarifier or settler by substituting projected area for the surface settling area of a conventional clarifier.
The compact design of this Lamella Clarifier 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 while cutting down the installation costs. Minimal moving parts mean low maintenance costs.
Operating Principle : Our Lamella Clarifier with a series of inclined plates are arranged to form a separate sedimentation chamber between adjacent plates. Raw water is first fed to Static Mixer and chemicals such as alum, poly electrolyte are added prior to static mixer for proper mixing of chemicals in water. Water from static mixer enters in Flocculator in which paddle type agitator is provided for gentle mixing. Polymer is added for flocculation of coagulated particles.
