# Improving Membrane-Based Water Filtration

Whether you are running a power plant, operating a farm, or are just thirsty, access to affordable, clean water is vital to human life and industry. A common means of cleaning and desalinating water—reverse osmosis—forces water through ultra-thin sheets of plastic, but the process is slow and consumes a lot of energy. Here, NIST researcher Chris Stafford is using a modified commercial instrument to measure the characteristics of different chemical formulations of these sheets to see how they perform under real-world conditions with the goal of improving their throughput and energy efficiency.
