Abstract
An improved lamella separator which reduces the contamination of the clear liquid output thereof in comparison with conventional lamella separators of the prior art. In a preferred embodiment thereof, the thickness of the feed liquid layer containing solid material is monitored at one or more regions in each of the channels of the separator so that when the thickness thereof approaches or exceeds about one half the channel depth in one or more channels, a control system responsive thereto maintains such thickness in such one or more channels at less than one half the channel depth.
