<p>A settler for liquids to be purified comprising a tank (11) which embodies a plurality of hollow truncated-cone shaped elements (15) stacked coaxially with their minimum diameter facing the tank bottom and delimiting intermediate passages (16) which extend conically from the element centre holes towards the periphery of the tank. In proximity to the lower truncated-cone shaped element, an intermediate horizontal partition (19) is provided, which divides the tank into a lower chamber (A), to which an inlet duct for the delivery of dirty liquid is connected, and an upper chamber (B) to which an outlet duct for purified liquid is connected. <IMAGE></p> |
