Document Type and Number:

Japanese Patent JP2014018782

Kind Code:

A

Abstract:

To provide a system and a method for cleaning a filtration film of ballast water treatment which have high cleaning efficiency and remarkably excellent degradation efficiency in degrading a persistent cake layer peculiar to ballast water treatment.

A system for cleaning a filtration film of ballast water treatment, which cleans the filtration film for the ballast water treatment with cleaning liquid, comprises: circulation piping which circulates the cleaning liquid in a manner that brings the same in contact with the filtration film: a chemical agent supply device which supplies the cleaning liquid in the circulation piping with a chemical agent: a micro bubble supply device which supplies the cleaning liquid in the circulation piping with micro bubbles; and a circulation pump which circulates the cleaning liquid in the circulation piping to bring the cleaning water containing the chemical agent and the micro bubbles in contact with the filtration film.
