Efficient water treatment with the lamella clarifier Lamella Separator of Leiblein

The lamella separator (also lamella clarifier) separates settleable solids (particles) from liquids and is used for instance in the treatment of process water and waste water.

Basically all solids that sediment in a given time, can be separated easily and economically with the lamella separator. Depending on the density those are usually solids larger than approximately 50 μm in diameter. For separating smaller particles and turbid substances, flocculants are used in order to create settleable flakes.

Efficient sedimentation – technology made by Leiblein Functional principle of the lamella separator

The lamella separator is a pressure-less system. The untreated water is pumped or flows by gravity into the inlet channel of the lamella clarifier where it flows downwards (❶). Below the lamellae the flow is reversed and streams up through the lamellae (❷). The solids settle down countercurrently on the lamellae (❸).

The clarified water flows further upwards and via a special overflow weir to the outlet (❹). The solids slide down along the lamellae and accumulate in the sludge funnel (❺). In order to keep the sludge flowable it is possible to add a scraper in the area of the funnel tip. Depending on the subsequent process steps the sludge is continuously or discontinuously removed (❻).

Our products are available to rent for pilot tests. Due to our extensive rental park, we can put together complete test systems individually for your task.

High efficiency Benefits of the lamella separator

  • Compact design: saves more than 85% of space compared to conventional sedimentation tanks
  • As a result of the 60 degree slant of the funnel, a compact sludge is created which can be transported precisely e.g. via pumps. That is why no manual sludge handling is required.
  • No moving parts. Only by the usage of a scraper there is a drive with a shaft.
    > almost no maintenance
    > low-energy system
