Abstract

PURPOSE: To prevent filtration speed drop due to ageing, by ultrafiltering the liquid to be treated after irradiating it with ultraviolet rays from an ultraviolet sterilization lamp.
CONSTITUTION: The liquid to be treated is fed with pump 2, subjected to irradiation of ultraviolet rays from ultraviolet sterilization lamp 5, and introduced into ultrafiltration module 1, thus permitting filtered water QP to be obtained. When necessary, lamp 5 is incorporated in the recirculation line of the ultrafiltration apparatus to irradiate the liquid with ultraviolet rays.
