How to make a black box talk? A review of 50 low-pressure membrane autopsies
This paper looks at the results of autopsying 50 MF/UF modules received from facilities around the world treating water for different applications.The gathered data show that most of the time, the autopsy succeeds in drawing up a cause and effect scenario explaining the observations recorded on sites. The reasons for production loss and integrity f...
How to Best Extend the Membranes Lifetime? A Modules Management Strategy that Leverages 25 Years of Experience in Operating Membranes Facilities
The paper gathers the best practices of 25 years of experience in operating MF/UF membrane facilities and is based on an overview of 10 water treatment plants equipped with different membrane technologies of different generations. The paper notes the three key stages when the MF/UF system has to be secured: project design phase, day-to-day operati...
Impact of organic matter on fouling propensity of a new ultrafiltration membrane with low adhesive surface - a study based on 10 different waters
Ultrafiltration (UF) membranes are widely used to treat surface water due to their capacity to remove colloids, particles, pathogens and virus. Today, they are also applied for reverse osmosis pre-treatment of wastewater reuse and desalination in order to address the problem of water shortage. However, membrane fouling by organic matter remains a k...
