The lamella clarifier separates sedimentable suspended solids from liquids for the treatment of process wastewater. Compared with the traditional sedimentation tank, the lamella clarifier occupies a smaller area and settles suspended solids faster and easier in a given time.
The sedimentation performance depends on the effective sedimentation area and is independent of the sedimentation depth. Lamella plates are installed inside the tank as a module. The effective sedimentation area of lamella clarifier is the accumulation of the projected area of the lamella plates not the occupied area.
Lamella clarifier are structures in wastewater treatment that utilize the principles of sedimentation and filtration to settle suspended matter in the water. In terms of design, they can be divided into two types: gravity and inclined plate. Gravity type is to use gravity to make the suspended material sink.
Flotation is an effective wastewater treatment process designed to treat for total suspended solids (TSS), BOD/COD (Biological/Chemical Oxygen Demand), and Fats, Oils, & Grease (FOG).
Oil refineries refers to a factory that processes crude oil extracted from underground through distillation, catalysis, cracking, pyrolysis, hydrorefining and other technological processes to produce products such as diesel, gasoline, kerosene, lubricating oil, petroleum coke, asphalt and ethylene.
Flocculation is a key process in water treatment where fine particles suspended in water are brought together into larger clumps called flocs. These flocs are easier to separate from the water, making the treatment process more effective. The formation of flocs is achieved by adding specific chemicals known as flocculants, which help particles bind together.
Lamella Clarifier is an improved settling tank that installs a set of inclined plates in the settling area of a regular settling tank. The removal rate of the lamella clarifier can reach up to 95%. Lamella Clarifier is based on the shallow tank theory, and the settling effect is related to the settling area. By installing inclined plates, the settling area has been increased. The effective settling area of the lamella clarifier is influenced by the design and arrangement of the inclined plates, which enhance the sedimentation process by increasing the surface area. The installation angle of these inclined plates are 60°, and the spacing between the plates is 80mm. This design creates laminar flow on the inclined plates, reducing hydraulic dead zones and eddies.
