Abstract: A rotary filter comprising (i) a housing comprising a first wash zone comprising a first wash fluid input zone, a final wash zone comprising a final wash fluid input zone, and one or more intervening wash zone(s) each comprising a wash fluid input zone; (ii) a control head comprising a first wash fluid output zone, a final wash fluid output zone, and one or more intervening wash fluid output zone(s); and (iii) a filter drum positioned within the housing and rotatable about its axis within the housing; and (iv) means to transfer wash fluid in counter-current flow, relative to the direction of rotation of the filter drum, from a wash output zone to a wash input zone of a preceding wash zone; characterised in that the rotary filter is configured to pass wash fluid via the filter drum from a wash fluid input zone (IZ n ) to the wash fluid output zone (OZ n ) of the same wash zone (n) and additionally to the wash fluid output zone of a preceding wash zone.
