A process and apparatus for clarifying a liquid loaded with suspended solid substances by decanting said substances, wherein the liquid to be treated is caused to flow along a flow path at least one portion of which is an upwardly directed flow path portion having a geometrical axis inclined with respect to the horizontal, said flow path portion being defined within an enclosure in which said liquid flows between plates arranged in at least two groups, each group containing substantially equidistant positioned plates disposed parallel to said inclined axis, said plates of each one of said groups being parallel to each other, and the parallel plates of each group forming with the vertical plane comprising said inclined axis an angle different from 90 degrees, while forming with the plates of the other group an angle of between about 20 degrees and 75 degrees, whereby the suspended substances are deposited on said plates and then slide downwardly thereon toward the wall of said enclosure.
