WATER TREATMENT APPARATUS AND METHOD FOR TREATING WATER

摘要

Provided are a water treatment apparatus capable of destroying microorganisms in water such as ballast water without requiring a large amount of force, and a method for treating water. A water-hammer device (6) that is installed in a pipe (3) for passing water containing microorganisms and applies water-hammer pressure generated by quick closure of a valve to water in the pipe (3) to destroy and eradicate the microorganisms in the water or other water makes it possible to destroy and eradicate the microorganisms in the water such as ballast water without requiring a large amount of force or using any chemicals or the like. It is thereby possible to perform water treatment without any adverse effect on the environment and at a low cost.
