Clarifiers - Lamella Clarifiers

 

Fluid Systems Lamella Clarifier is a compact, inclined plate type clarifier used for clarification of water & waste water having higher suspended and colloidal particles. The principle is based on settlement of colloidal particles by providing a larger surface area

 

Smaller Footprint:

 

The Lamella Clarifier provides a means of water clarification at a large saving of surface area. (Up to 90 %)

 

Operating Principle           


The clarifier consists of a series of inclined plates, which are arranged to form a separate sedimentation chamber between adjacent plates. 

 

The raw water is first fed to Static Mixer. Chemicals like 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 particle

 

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.

 

Advantage.

 

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. A single operator without the need to shutdown the unit, drain the tank contents and disassemble any tank internals can easily remove each individual lamella plate. The plate can be easily slide up for inspection and maintenance as required. It can be operated for any length of time continuously without shutdown. Lamella does not buildup deposits and there is no specific frequency of cleaning required and thereby minimizing the maintenance problems. The thin layer of sludge formed on each plate picks up the fine flocs present in water, which is rising up.
