Ultrafiltration is one membrane filtration process that serves as a barrier to separate harmful bacteria, viruses, and other contaminants from clean water. An ultrafiltration water system forces water through a .02 micron membrane. Suspended particles that are too large to pass through the membrane stick to the outer membrane surface.

Mar 09, 2017Membranes are a semipermeable material that allow various particle sizes to either flow through or be trapped by the membrane, and the degree of separation largely depends on particle size. Membranes remove finer particles (generally less than 2 μm in size) than media filtration (which can remove particles 1 to 2 μm in size and greater).

Jan 31, 2011Reverse Osmosis membranes clean themselves as they process water, so it's really healthier if the membrane has to work longer to fill the tank. Think of it this way: If you draw off a gallon of water, a 24-gallon-per-day membrane will refill the tank at the rate of about a gallon per hour.
