Lamella clarifier description

Lamella clarifier also called inclined plate sediment tank. It is good at high efficient combined type settling tank; set many dense inclined tube packing in sediment area, to make the suspended impurity in water sediment, water rise flow along inclined tube, the separated sludge down to the tank bottom along the inclined tube by gravity, then discharge it in concentration. Such tank can improve sediment efficiency 60~70%, it can improve treatment capacity 3~5 times in the same area. It can design different flow rate inclined plate sediment device according to raw waste water test report, it need dose flocculant usually.

Lamella clarifier principle

The Lamella clarifier works when a solid/liquid stream that has been flocculated, enters a tank, and flows upward between a pack of inclined plates. The solids fall to the plate surface, where they slide by gravity down to a sludge collection hopper. The clarified effluent flows through orifice holes and exits the top of the settler. The sedimentation process in a Lamella clarifier involves the settling of suspended solids as the wastewater flows through inclined plates. These inclined plates, typically positioned at a 45 to 60-degree angle, increase the effective settling area within a compact footprint. Gravity drives the settling; as particles descend, the plates guide them to be collected at the bottom, making the removal process more efficient compared to conventional clarifiers.
