Lamella and Sedimentation Systems

Yes, lamella systems are 5-10 times more efficient than conventional sedimentation tanks. The effective sedimentation surface significantly increases due to the inclined plates. For the same treatment capacity, 80% less space is used.

This angle range is the optimum slope that allows particles to slide off the plate surface and collect at the bottom. At lower angles, particles adhere to the plate, while at higher angles, the sedimentation efficiency decreases. The ideal balance point is 55°-60°.

Material selection is made according to the characteristics of the wastewater. For general applications, epoxy-coated carbon steel is preferred. For corrosive wastewaters, 304 or 316 stainless steel is used. In some special applications, plastics such as PP and PE may also be preferred.

Lamella systems are commonly used in industrial wastewater treatment for pre-settling after coagulation-flocculation and before biological treatment, as well as in drinking water preparation facilities. They are also preferred in sectors such as mining, food, and metal plating.

Lamella systems require minimal maintenance. Periodic cleaning of the plate surfaces and inspection of the sludge collection area is sufficient. Thanks to the modular plate design, individual cleaning or replacement can be easily performed. A general inspection once or twice a year is adequate.

The modular structure of lamella systems allows for easy capacity increase. Capacity can be increased by 2-3 times by adding additional plate modules to the existing tank or by establishing parallel units. This feature offers a significant advantage in adapting to sectoral growth.
