摘要

The Portland Water Bureau (PWB) undertook a study in 2009-2010 to investigate foulingrntendencies of its unfiltered source water with UV equipment. The 12-month study was conducted withrnthree different UV reactors; two medium pressure reactors and one low-pressure high-output (LPHO)rnreactor. Results showed that the un-wiped medium-pressure lamp sleeves demonstrated significantrnamounts of fouling during the fall. During the remainder of the year the un-wiped medium-pressure lamp sleeves showed little or no fouling. The un-wiped LPHO sleeves demonstrated no significant fouling during any month of the year. PWB was able to use the results of this study to aid in the pre-selection process of UV equipment for full-scale design.
