Abstract
(EN)
A ballast water production method is provided with: a filtering step for passing raw water supplied into a housing (20) through a filter (21) from a first side that is upstream of the filter (21) to a second side that is on the downstream side; a volume-increasing step after the filtering step for increasing the volume of water present in the space on the second side inside the housing (20) while supply of raw water into the housing (20) is stopped; a pressurizing step after the volume-increasing step for pressurizing the inside of the housing (20) from the second side while supply of raw water into the housing (20) is stopped; and a rinsing step after the pressurizing step for passing fluid through the filter (21) from the second side to the first side while supply of raw water into the housing (20) is stopped.

La présente invention concerne un procédé de production d'eau de ballast qui est pourvu de : une étape de filtration pour faire passer de l'eau brute alimentée dans un boîtier (20) à travers un filtre (21) depuis un premier côté qui est en amont du filtre (21) vers un deuxième côté qui est sur le côté aval ; une étape d'augmentation de volume après l'étape de filtration pour augmenter le volume d'eau présent dans l'espace sur le deuxième côté à l'intérieur du boîtier (20) tandis que l’alimentation d'eau brute dans le boîtier (20) est arrêtée ; une étape de mise sous pression après l'étape d'augmentation de volume pour mettre sous pression l'intérieur du boîtier (20) tandis que l’alimentation d'eau brute dans le boîtier (20) est arrêtée ; et une étape de rinçage après l'étape de mise sous pression pour faire passer le fluide à travers le filtre (21) depuis le deuxième côté vers le premier côté tandis que l’alimentation d'eau brute dans le boîtier (20) est arrêtée.
