Abstract
23,146. Naylor, G. W., and Naylor, J. F. Nov. 27. Tanks ; aerating.-Tanks for purifying sewage by aerating in presence of sludge are divided by partitions 3 having opening or pipe connexions so that sewage and sludge pass successively through the compartments by gravity. Aerating-devices consisting of porous tiles 4, Fig. 2, through which air is forced, may be placed at the back of the partitions so that injection of air assists the circulation. The partitions may be inclined or may carry baffles 5. The partitions may pass to the bottom of the tank and be fitted with bent pipes 7, Fig. 4, which may pass to the surface of the liquid in the compartments, or with S-shaped pipes, two limbs of which are on the inlet side of the partition and the third on the outlet, the connexion passing through the apper part of the partition. The whole of the tank may be covered with porous tiles or a cloth false bottom through which air is forced. Air jets may be attached to the partitions or supported in the compartments. An automatic outlet valve for the sewage, which comes into action when a certain is attained and an automatic device operated by a float to start and stop the air supply, may be provided. Specification 729/14 is referred to.
