The use of membrane technology for the production of drinking water is becoming more commonplace and more cost-effective every year. Many utilities are converting to membrane filtration to help fortify their facilities for current or future regulations. The author has been fortunate to at the front lines of the membrane wave in Ohio – having participated in the design of approximately 75% of all membrane water treatment plants in Ohio. The objective of this presentation is to highlight the advantages of utilizing membranes utilizing real life case studies of approximately 20 water treatment facilities in Ohio where membranes were installed instead of conventional treatment. Water quality / goals and treatment process selected for each will be discussed – along with a lesson learned from each project. Unique concentrate disposal techniques on several of the projects will be discussed – along with the proposed changes to the TDS regulations in Ohio that will make it much more challenging to construct high pressure membrane plants in Ohio.
