Lamellenklärer

Lamellenklärer, also known as lamella settlers or plate settlers, are devices used in water and wastewater treatment for solid-liquid separation. They consist of a series of inclined plates or lamellae arranged in parallel. The wastewater flows through the spaces between these lamellae. As the flow moves through the lamellae, the velocity decreases, allowing suspended solid particles to settle out due to gravity. The inclined surface of the lamellae facilitates the downward movement of the settled solids towards a sludge collection area at the bottom of the clarifier. The clarified water then flows upwards and out of the settler. Lamellenklärer are particularly effective in treating flows with a high concentration of settleable solids and are often used as a preliminary treatment step. Their compact design and high overflow rates make them a space-saving alternative to conventional settling tanks. They are commonly found in applications such as industrial wastewater treatment, municipal sewage treatment, and stormwater management. The efficiency of a lamella clarifier depends on factors like flow rate, particle size and density, and the angle of the lamellae.
