The present invention relates to a method for inhibiting the biofouling of the surface of a membrane caused by biofilm by immobilizing biofilm formation inhibiting-microorganisms to a microorganisms-immobilized container in a membrane process for water treatment, and provides a container in which biofilm formation inhibiting-microorganisms are immobilized, comprising a permeable container, and biofilm formation inhibiting-microorganisms immobilized on the inside of the container. In addition, the present invention provides a water treatment apparatus using a membrane, comprising: a reaction tank for accommodating water to be treated; a membrane module for water treatment; and a container in which biofilm formation-inhibiting microorganisms are immobilized, placed inside the reaction tank. |
