This presentation provides an overview of "lessons learned" from large-scale membrane technology projects,with particular focus on low-pressure filtration (UF/MF). Specific topics discussed include: key design and integration issues, procurement, market drivers, technical differentiators, startup and operations,membrane repair and replacement, residual management, and regulatory requirements. This experience is based on the authors' first-handknowledge from working on more than 120 membrane-related (RO/NF/UF/MF) projects totaling greater than4,000 million liters per day (ML/d) (> 1,000MGD) installed capacity, of which 2,500 ML/d (> 650 MGD) arefrom direct design experience. The presentation culminates with a look at the two largest UF membrane plants in North America,the 378 ML/d (100 MGD) Twin Oaks Valley WTP in San Diego, California, and the 360 ML/d (96 MGD)Lakeview WTP west of Toronto, Canada. Several key issues involving constructing, operating,monitoring and maintaining membrane plants, while consistently producing high quality water, arepresented. Includes tables, figures.
