Wastewater Demineralization by Tubular Reverse Osmosis Process.

摘要

A 16 1pm (4.2gpm) tubular reverse osmosis pilot plant was operated at Pomona Advanced Wastewater Treatment Research Facility for over one year. The purpose of the study was to investigate the applicability of the tubular reverse osmosis process to wastewater demineralization. The pilot plant operational goal was the study of the membrane life. The feed was carbon-treated secondary effluent. This study lasted 7,165hours until the operating membrane modules reduced from the original 32modules to 12modules as a result of membrane module failure. It was subsequently decided to make use of the remaining 12modules in the system for exploring the behavior of the membrane process in treating primary effluent. The system treated primary effluent during the third phase for a period of 2,074hours. Repeated membrane failure resulting from poor mechanical design of the system obviated drawing significant conclusions.
