Appl. No.:

11/548611

Inventors:

Chenniah Nanjundiah - San Diego CA, US
Larry L. Hawn - Laguna Niguel CA, US
Jeffrey M. Dotson - Fort Worth TX, US

Assignee:

Pureline Treatment Systems, LLC - Irvine CA

International Classification:

B01J 7/00
C25B 1/26

US Classification:

204266, 422305, 205618

Abstract:

A chlorine dioxide solution generator includes a chlorine dioxide gas source. An eductor system is fluidly connected to the chlorine dioxide gas source for at least partially effecting the dissolution of chlorine dioxide gas into an aqueous liquid stream. An absorption system is fluidly connected to the eductor system that is capable of effecting additional dissolution of the chlorine dioxide gas into said aqueous liquid.

International Classification:

B01F 3/04

US Classification:

261075000

Abstract:

A chlorine dioxide solution generator includes a chlorine dioxide gas source and an absorption loop for effecting the dissolution of chlorine dioxide into a liquid stream. A gas transfer assembly is interposed between the chlorine dioxide gas source and the absorption loop. The gas transfer assembly includes a gas transfer pump and an exhaust manifold assembly. The exhaust manifold assembly includes a manifold conduit defining an interior volume for directing the pressurized chlorine dioxide gas stream from the pump outlet to the absorption loop. The manifold conduit interior volume is sufficiently large to inhibit chlorine dioxide decomposition in the pressurized chlorine dioxide gas stream by induce a pressurized chlorine dioxide gas stream temperature within the manifold conduit of less than about 163 F. (73 C.).

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.
