Membranes

Membranes are special types of filtration membranes that the filters act as a barrier to separate contaminants from water, or they remove the particles contaminating the water. Different filtration processes include nanofiltration, reverse osmosis, ultrafiltration and they all use a membrane in their different filtration processes. When using Reverse osmosis pressure is applied to a semipermeable membrane that allows the water molecules to pass through while flushing the dissolved inorganic compounds to the drain. It separates the water in to two pathways.  Ultrafiltration doesn’t separate the water like a reverse osmosis membrane. It actually is just an ultra fine particulate or sediment filter. Nanofiltration membrane works very similar to reverse osmosis, except the filtration is not quite as fine.
