Reverse Osmosis (RO) technology is the abilities of typical water filtration by using a semipermeable membrane to remove impurities from water. Good Reverse Osmosis water filtration provides a low-maintenance, reliability option to help achieve clean, great result water each and every day.
In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property, that is driven by chemical potential differences of the solvent, a thermodynamic parameter. Reverse osmosis can remove many types of dissolved and suspended species from water, including bacteria, and is used in both industrial processes and the production of potable water.
Ultrafiltration (UF) is a variety of membrane filtration in which forces like pressure or concentration gradients lead to a separation through a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained while water and low molecular weight solutes pass through the membrane in the permeate (filtrate).
This separation process used in industry and research for purifying and concentrating.
