Abstract
Official abstract text for this publication.
The present invention relates to a method for reduce treating ballast water which has been subjected to a biocidal treatment with a chlorine-based oxidizing agent or an oxygen-based oxidizing agent, by using a tablet or pellet of sodium sulfite.
First claim
Opening claim text (preview).
1 . A reduction treatment method for treating ballast water which has been subjected to a biocidal treatment with a chlorine-based oxidizing agent or an oxygen-based oxidizing agent, the method comprising using a tablet or pellet of sodium sulfite. 2 . The reduction treatment method for treating ballast water according to claim 1 , further comprising bringing the ballast water which has been subjected to the biocidal treatment into contact with the tablet or pellet of sodium sulfite. 3 . . The reduction treatment method for treating ballast water according to claim 1 , further comprising dissolving or suspending the tablet or pellet of sodium sulfite in water, and adding the resulting aqueous solution or suspension to the ballast water which has been subjected to the biocidal treatment. 4 . The reduction treatment method for treating ballast water according to claim 1 , further comprising filling a container with the tablet or pellet of sodium sulfite, and allowing the ballast water which has been subjected to the biocidal treatment to pass through an inner cavity of the container, thereby bringing it into contact with the tablet or pellet of sodium sulfite. 5 . The reduction treatment method for treating ballast water according to claim 1 , wherein the ballast water which has been subjected to the biocidal treatment with the chlorine-based oxidizing agent is obtained by electrolysis of a ballast water. 6 - 11 . (canceled) 12 . The reduction treatment method for treating ballast water according to claim 1 , wherein the tablet or pellet of sodium sulfite comprises sodium sulfite and sodium chloride as an excipient, and a weight ratio of sodium sulfite to sodium chloride is from 40/60 to 60/40.
