The sand filter consists of a set u- oi superposed cylindricalsections (4) fitted with cone-shelves (14), so constructedas to enable- the sand to pass without hindrance to thebase of the apparatus, the annnli (20) preventing themixing of the filtered and unfiltered juice. Above ami. below the shelves are perforated plates. Tla juice tobe filtered entering at (5) is admitted by the automaticarrangement (7, 8) and passes through the -and (11) oroverflows by the side inlets (13) to the space (28) (Fig. 3)between the shelves (14) and the perforated plates (16),through the sand downwards in parallel streams ; thefiltrate passing through the perforated plates (15) (Fig. 2)away by the outlets (18) where the outflow is controlledby regulating screws. To the base of the apparatus isconnected the washing apparatus (21) with a horizontalhollow sliding injection tube (22) and junction piece(23). by means of which the sand, saturated with scum,is carried away by the flow of water under pressure through - JOURNAL OF IH ~ 1 OF cHKMirU.
