The Need for Water Reuse Guidelines for Designing and Operating Membrane Facilities
AWWA Journal
November 2015
In a world in which every drop of water counts, membrane technology is emerging as a major innovation in water treatment and reuse. A lack of uniform standards affects the industry's ability to develop an effective water management portfolio, and the need for clear guidelines has never been greater. This article examines water reuse as well as the growing need for regulatory agencies to develop water quality standards and define a minimum number of parameters when using membrane technologies for water reuse applications.
