Analysis on the international convention forthe control and management of ships’ballast waterand sediments;

High concentration of hydroxyl radical is produced from H_2O and O_2 by the charge transfer in the strong electric field,by which the effect of treating ballast water is obvious.

One of the most important mechanisms for the introduction of non-indigenous organisms is transport in ship ballast water.

Discussion on the ship's ballast water treatment techniques

This paper describes the problems of public health harm and marine ecological environment destruction caused by unwanted aquatic organism and pathogen carried by ship's ballast water.

But ship's ballast water may carry pathogen and non-indigenous species, which might be circulated worldwide by ship and therefore cause pollution.

Based on the experimental data, the kinetic model of chlorine decay in electrolysed ships ballast water was found by means of Non-linear fitting.

If the raw seawater is simulated as ships ballast water and treated by electrolysing with an initial chlorine concentration of 4.

A review of costs of different methods for ships ballast water treatment is given in this paper.

Ship ballast water has damaged seriously the world's maritime environments and local economies,the International Maritime Organization(IMO) ruled that only the ballast water treated to a standard level can be discharged.

And in this study the author combined with the National Key Technology R&D Program "Technique of treating the ocean shipping ballast water by hydroxyl radical",designed the experimental system which was used to simulating ballast water,and detected relative objects.
