Siphon is cut out. Byopening and closing the corres-ponding valves in any of the other draining siphons any one ofthe main siphons may be cut out. The general plans here used, show the siphons only in con-nection with sand filtration. They can be used just as easily andsatisfactorily with the contact bed. Nor is it necessary thatthey be set in a straight line. A drawing on the next page showssix siphons set in a circular form. The principle is just thesame. li. /^L^r^ /VoTl/j.
