Membrane Filtration: The Technology of Choice
Widely recognized as the technology of choice for superior water and wastewater treatment,
membranes provide a physical barrier that effectively removes solids, viruses, bacteria and other
unwanted molecules. Different types of membranes are used for softening, disinfection, organic
removal, and desalination of water and wastewater and can be installed in compact, automated,
modular units. Membrane filtration units can also be installed in relatively small facilities that blend into
the surrounding area and can be fully automated to significantly reduce the required amount of
operator attention.
Recent advances in technology have significantly reduced the cost of membrane‐based systems.
Installation costs are lower because membrane systems don’t require large buildings or as much land as
conventional systems. Operating costs are reduced since today’s membranes produce more water and
remove more impurities while using less energy.
In the United States, regulations such as the Safe Drinking Water Act and the Long Term 2 Enhanced
Surface Water Treatment Rule have had a significant impact on municipal water treatment. This, in
addition to increasingly stringent wastewater discharge regulations, has promoted dramatic growth in
the implementation of membrane technology.
