Abstract

Liquid flowing through a housing is sterilized by being subjected to radiation which passes through a window transparent to ultraviolet rays. The liquid is prevented from contacting the window by an air pocket. The air in the pocket is maintained by introducing air into the liquid which either replenishes air absorbed from the pocket by the liquid at the air-water interface or prevents the liquid from absorbing air from said pocket.
