<p>A decanting unit consists of a chamber with an inlet (2) for the polluted liquid and an outlet (3) for the decanted liquid, with a channel (7) between them equipped with a series of parallel plates (8) through which the liquid circulates. The plates are able to tilt between an active decanting position, in which they are inclined relative to the vertical, and a vertical position for cleaning, with the tilt controlled by a float mechanism. The tilt of the plates is controlled by the plates themselves, which are made from a material with a density lower than that of the liquid being treated, eg. PVC, or by floats attached to some of the plates. The intervals between the plates can be varied by spacers of adjustable length.</p> |
