A process and apparatus for batch treatment of a liquor to separate, by way of example, a suspension of a contaminant from a liquor is disclosed. The batch treatment apparatus comprises, a singl e batch vessel that has discharge outlets at an upper and a tower level of the vessel, and an agitator that is operable in accordance with the batch treatment process to mix Lhe contents of the vessel. The batch treatment process comprises, forming floccs of the contaminants and a carrier which settle rapidly tow- ards the base of the vessel, discharching the relatively contaminant free liquor through the upper discharge outlet, breaking bonds of the floccs so that the carrier separates from a sludge of the contaminant and llocculent residue, discharging the sludge through the lower discharge outlet, and re-using the carrier in the treatment of a n ew batch of liquor.
