Abstract
A method and system of ozone treatment diverts a portion of water from a flow of water in a conduit, injects ozone into the portion to provide an ozonated portion, and recombines the ozonated portion with the flow of water in the conduit. Another method and system identifies a species-destructive reaction product of ozone with a water constituent, determines a life of the reaction product, and contacts ozone with a water containing the species for a period determined according to the determined life of the reaction product.
Claims16
A method of ozone treatment, comprising:
- identifying a species-destructive reaction product of ozone with a water constituent;
- determining a life of the reaction product;
- and
- contacting ozone with a water containing the species for a period determined according to the determined life of the reaction product.
A method of ozone treatment, comprising:
- diverting a portion of water charging into a ballast tank of a vessel;
- injecting ozone into the portion to provide an ozonated portion;
- and
- recombining the ozonated portion with the water charging into the ballast tank;
- wherein the water is seawater containing bromine that reacts with ozone to provide an OBr− reaction product, and a retention period between injecting the ozone into the portion and recombining the injected ozone portion with the water charging into the tank is controlled below a specified time limit such that the ozone is contacted with the seawater for a period controlled to maintain a molar ratio of Br− to OBr− above 2.7.
A method of ozone treatment, comprising:
- diverting a portion of water charging into a ballast tank of a vessel;
- injecting ozone into the portion to provide an ozonated portion;
- and
- recombining the ozonated portion with the water charging into the ballast tank;
- wherein a retention period between injecting the ozone into the portion and recombining the injected ozone portion with the water charging into the tank is controlled below a specified time limit of 5 seconds.
