Title: Treatment of sludge dredged from harbors with water containing dissolved ozone
Inventor: LEITZKE ORTWIN
IPC: C02F1/78
Filed: 1999-03-03
Abstract: Sludge dredged from harbors is treated with water containing dissolved ozone. Sludge is drawn from the river/harbor bed (4a) into a rotary piston pump (4b) that delivers it to reaction pipe (5c). Water from line (3a) is mixed with ozone (and some unreacted oxygen), supplied by a conventional generator (2a), to line (2b) where it is pumped by centrifugal pump (3b) to line (5c). The required reaction is complete as the mixture from (5c) enters the degassing vessel (5). The unreacted oxygen is released here as the stream hits an inclined plate (5a) and is withdrawn through line (7) and drier (8) to be returned to the ozone generator. Additional oxygen is supplied by cylinder (9). Treated sludge is withdrawn through valve (5d), which also regulates the water level in (5) at about 60% of its total height. The sludge is stored in the vessel on which the apparatus is installed for subsequent disposal at sea. An inner cylinder, that leaves a circumferential space (5b), is provided to ensure that water leaving through line (3a) is as clear as possible. A system pressure in excess of 5 bar is preferred in all sections following the pump discharges. The principal contaminant to be destroyed is tributylzinc which is leached from the protective paint of the hulls.
