Abstract
An on-board ship water treatment system includes such features as drinking water purification and ballast water treatment. The on-board ship water treatment system includes an on-board ship water treatment vessel. A chlorine dioxide generator is fluidly connected to the on-board ship water treatment vessel. The chlorine dioxide generator includes a chlorine dioxide gas source and an absorption loop for effecting the dissolution of chlorine dioxide into a liquid stream. The absorption loop is fluidly connected to the chlorine dioxide gas source. A gas transfer assembly is interposed between the chlorine dioxide gas source and the absorption loop.
Claims34
An on-board ship water treatment system comprising:
- (a) an on-board ship water treatment vessel;
- and
- (b) a chlorine dioxide generator fluidly connected to said on-board ship water treatment vessel, said chlorine dioxide generator comprising;
