Abstract

An improved method and apparatus for removing grit from sewage comprising passing sewage containing grit along a channel 33, the sewage passing initially through a straight elongate portion 37 of constant width 35 and of length 39 sufficient to stabilise the flow and subsequently passing the sewage around a bend portion 41 having an angle of at least 10 degrees from the straight portion 37 and, downstream of the bend 41, removing the grit from the flow via a port 51 situated at the inside of the bend 41 at the base of the channel via a grit hopper 67 coupled to the port and coupled to a draw-off point 71 to remove the grit for disposal.
