Since the first wave of adaptation of membranes in drinking water industry in early 1990?s, thousands of membrane plants have been constructed around the world. While membrane manufacturers have been relentlessly advancing the technology and the engineering community continuously improving the design of WTP facilities, severe membrane fouling and excessive membrane fiber breakage remain the two most unpredictable challenges to many membrane plants. These two issues are also big concerns shared by all future membrane facilities that are currently under planning. In addition, errors and mistakes do take place in membrane manufacturing, system design, construction and operation. To date, these types of challenges still exist in many membrane plants, although this information is not widely shared. Unlike conventional granular media filters, membranes are more susceptible to irreversible damages when designed operating conditions are not strictly followed, making membrane operation a challenging task to the water treatment plant operators. This paper will focus on membrane performance monitoring and operation optimization. Proper performance monitoring can help the plant to determine operation efficiency, allow for O&M cost tracking and projection, maintain membrane warranty, and to reduce costs on chemicals, energy, and membrane replacement. The presentation will include the following 6 topics.
