The Lamella Thickener is an inclined, shallow depth sedimentation device. It performs the same function as a conventional Thickener, but it occupies only a fraction of the space. For an initial understanding of the Lamella Thickener, it is best to restrict the initial discussion to suspensions in which the particles exhibit "free settling."
