Abstract

PURPOSE: To raise water-pasteurizing efficiency, while facilitating the installation of a pasteurizer and inhibiting its contamination, by using a thermoplastic copolymer of perfluoroethylene and tetrafluoroethylene as a water-isolating transparent wall through which ultraviolet rays can permeate.
CONSTITUTION: Thermoplastic resin prepared by copolymerization of perfluoroethylene and tetrafluoroethylene is formed into a cylindrical transparent wall 11. The transparent wall 11 is located helically around an ultraviolet pasteurizing lamp 12. Water to be purified is let flow through the helical transparent wall 11, and ultraviolet rays are irradiated to the water. Consequently, the transparent wall 11 is not deteriorated, contaminants hardly adhere onto the transparent wall 11, and pasteurized water is obtained with high efficiency.
