Abstract

1504510 Aerating and agitating slurries BOC INTERNATIONAL Ltd 23 May 1975 [30 April 1974] 18971/74 Heading B1C Mud deposited at the bottom or sides of a body of flowing or stationary water may be treated by directing at it a stream of pressurized water in which is dispersed pure oxygen or a gas containing a greater proportion of oxygen than does air, and optionallyl chlorine or ozone. The discharge nozzle may produce several radial streams, and the apparatus for producing the gasenriched stream may be used from the bank or mounted on a barge. Where the body of water is tidal it is preferable to begin treatment at high tide.
