Abstract

939,696. Sand filters. R. HEBERT. March 6, 1961, No. 8088/61. Class 46. 88 Boxes 36, open at the bottom, but closed at the top by perforated plates 50, divide up a filter bed 11 into cells 35 to prevent channelling and lateral displacement of the bed material by upflowing wash-water. The perforations 57, Fig. 4, extend also through strips 55 attached to the tops of the plates 50 so that upflowing wash-water can discharge into gutters 56 and flow thence over a wall 18, Fig. 3, into a drain 19. The boxes rest on a false floor which consists of baffle strips 47, 48 on juxtaposed perforate rectangular plates 45 supported by legs 49. Liquid to be filtered is supplied through a gate valve 24, Fig. 3, from the reservoir shown to the left of the gate valve and a wall 13.
