Abstract
Abstract IN A STERLIZER UNIT FOR FLUID MEDIA WHEREIN A TRANSPARENT PIPE IS USED TO CONDUCT THE FLUID MEDIA AND A SOURCE OF GERMICIDAL RADIATION IS USED TO IRRADIATE THE FLUID MEDIA THROUGH THE PIPE, THE IMPROVEMENT DISCLOSED COMPRISES THE USE OF A PIPE COMPOSED OF FLUORINATED ETHYLENE PROPYLENE IN COMBINATION WITH ULTRAVIOLET LAMPS. IMPURITIES CONTAINED IN THE FLUID MEDIA BEING TREATED DO NOT STICK THEREBY PROHIBITING FILM BUILDUP ON THE INNER SURFACE THEREOF SO THAT THE UNIT IS OPERATIONAL OVER EXTENDED PERIODS OF TIME. IN ADDITION, DECOMPOSITION OF THE FLUID CONDUCTING PIPE IS AVOIDED UNDER EXTENDED EXPOSURE TO ULTRAVIOLET RAYS.
