Let it be supposedthat at the last rise in the tank siphon No.l had operated, drain-ed the water from the tank and refilled its own trap.The drainingsiphoms operate the same as before with one exception. The valveb in draining siphon B is closed and cannot drain the contentsof well No.2 into siphom No.S. Valve a^in draining siphon Bis open,.so the contents of well No.2 is drained into siphon No.SAll the traps are now full with the exception of siphon No.S.This will be the one to operate at the next rise of water in thetank. Siphon No.2 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
