Filter comprising a halogen release system and chitosan

摘要

A water treatment system is described in which an inlet is in fluid communication with an outlet. A first region including a halogen release system is located downstream from the inlet and upstream from the outlet. A second region including chitosan or a chitosan derivative is located downstream from the first region and upstream from the outlet. A filter including a housing containing the water treatment system is also described. A method for treating water in which water flows through the water treatment system is also described.
