The floating decanter apparatus of decanting supernatant from a vessel or basin without drawing floating solids or scum includes a weir for decanting supernatant from the basin and a float for buoyantly supporting the weir in the basin. An actuator is provided for moving the weir, relative to the float, from a first position at which a discharge opening of the weir is above the surface level of the supernatant in the basin, to a second position at which the discharge opening is below the surface level, thereby enabling the supernatant to enter the weir from below the surface. Solids are prevented from entering the discharge opening before and during decanting of the supernatant and means are provided for removing the supernatant to a location outside the basin.
