Lamellar sedimentation units and Lamella packs

Lamella clarifiers - Lamella separators - Lamella packs for installation in concrete or steel tanks.

Lamellar settling tanks (lamella separators or plate thickeners) are used for separation of settleable particles contained in water.

In general, particles larger than approximately 50 μm (with a higher density than liquid) can be separated by precipitation. Particles of smaller size can be separated by means of koagulnti to be added and mixed in a reaction tank (flocculator) equipped with a mixer, which will ensure mixing of the coagulant with water.

The plate packs are made of modules of polystyrene having a shape that increases the specific surface area of the precipitator.

The plate pack can be produced in shape, size and slope according to the specific customer needs. 

The structure of the package is self-supporting. To facilitate the procedure for mounting and dismounting plate pack is placed in a metal frame made of stainless steel AISI 304, AISI 316L or galvanized profile.
