Cleaning method and filter cleaning method of ballast water treatment membrane cartridge

摘要

To provide a cleaning method for ballast water treatment membrane cartridges can be removed efficiently and (microbial) rapid substances adhering to the membrane surface of challenges ballast water treatment membrane cartridge. A method for filtering the ballast water to be supplied to the membrane cartridge 3 to be in preparation for a spiral membrane module, a [SOLUTION] ballast water, stop the filtration, the membrane cartridge 3, and an agent that generates gas In the state filled with cleaning liquid, it is a closed system the membrane cartridge 3, and immersing the membrane module in the washing liquid, by increasing the pressure of the membrane cartridge 3 by gas generated from the chemicals adhering to the membrane surface material cleaning method for ballast water treatment membrane cartridge is characterized in that it is impregnated with chemicals between the film surface and to strip the deposited material from the membrane surface.
