Lamella Clarifier

Additional Details

Our Lamella Clarifier is a compact, inclined plate type clarifier used for clarification of water & waste water having higher suspended and colloidal particles. This is based on settlement of colloidal particles by providing a larger surface area. The Lamella Clarifier provides a means of water clarification at a large saving of surface area. (Up to 90 %) Operating principle Our 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. The flocculated water enters the Lamella near the bottom section of the plates and flows upward between them. As the water moves upwards, solids settle downward by the plates onto the surface area provided by the plates. Solids continue to slide down the plate surfaces to the collection hopper. Near the top of each plate, water leaves through a pair of circular openings in the adjustable weir plate located along both the sides of the clarifier. The weir plate is set horizontally to provide proper distribution of liquid through each circular opening. Sludge is periodically drained by opening the drain valve at the hopper bottom.

Technical Specifications

    Stable flow and excellent effluent quality
    Occupies 1/10th of space required by conventional clarifiers
    No moving parts, thereby minimizing the maintenance problems
    Sludge thickener zone having four slopped hopper bottom completely replaces the extra thickness
    Maximum effective settling area per m2 of the plate area due to better hydraulic distribution and collection arrangement
