PROCESS FOR PRODUCING SHIP BALLAST WATER, SHIP BALLAST WATER PRODUCING APPARATUS AND USE THEREOF

A process for producing ship ballast water, comprising the microbe removal step of causing seawater to pass through a microbe filtration membrane to thereby remove microbes from the seawater and the back washing step of cleaning the microbe filtration membrane by back washing. Microbes of seawater c...

Zusammenfassung:A process for producing ship ballast water, comprising the microbe removal step of causing seawater to pass through a microbe filtration membrane to thereby remove microbes from the seawater and the back washing step of cleaning the microbe filtration membrane by back washing. Microbes of seawater can be removed by a process other than that for annihilating them. Un procédé pour la fabrication d'eau de ballast de bateau, comprenant l'étape d'élimination des microbes en faisant passer l'eau de mer au travers d'une membrane de filtration de microbes pour de ce fait éliminer les microbes de l'eau de mer et l'étape de lavage à contre-courant pour nettoyer la membrane de filtration de microbes par un lavage à contre-courant. Les microbes de l'eau de mer peuvent être éliminés par un procédé autre que celui qui consiste à les anéantir.
