JOURNAL OF THE AMERICAN WATER WORKS ASSOCIATION. American Water Works Association, Denver, CO, 105(2):65-76, (2013).
Impact/Purpose:
The purpose of this JAWWA article is to inform the drinking water membrane professional community about methods and metrics for optimizing their membrane systems.
Description:
After a membrane filtration (i.e., microfiltration (MF) and ultrafiltration (UF)) system is designed, installed, and commissioned, it is essential that the plant is well-maintained in order to proactively identify potential design or equipment problems and ensure its proper operation. However, the strategic use of operational practices to optimize MF/UF system performance and the important metrics to track are not always commonly known. Such in-depth understanding may not be conveyed in operator training, and the applicable information is not captured in any one readily accessible reference. Consequently, this article has been prepared by the American Water Works Association (AWWA) Membrane Processes Committee of the Technical and Educational Council, Water Quality and Technology Division to compile the most useful contemporary knowledge regarding the methods and metrics for MF/UF system optimization into a single, concise resource, including essential background on the following topics: • Transmembrane Pressure • Temperature and Temperature Correction • Permeability • Chemical Cleaning Effectiveness • Backwash Practices • Maintenance Cleans • Integrity Testing • Integrity Maintenance and Repair • General and Preventative Maintenance
