Reverse osmosis (RO) is a separation process that uses water pressure to force a solvent through a membrane that retains a solute on one side and allows pure water solvent on the other side. More formally, it is the process of forcing a solvent from a region of high solute concentration through a membrane to a region of low solute concentration by applying a pressure in excess of the osmotic pressure. This is the reverse of the normal osmosis process, which is the normal osmosis process, which is the natural movement of solvent from an area of low solute concentration, through a membrane, to an area of high solute concentration when no external pressure is applied. The membrane here is semipermeable, meaning it allows the passage of solvent but not of solute.
The cartridges in this system must be replaced on a regular basis to maintain efficiency and to safeguard water quality. These cartridges work together to remove potential contaminants for your tap water and must be replaced every 6-12 months. Any significant change in performance of the system should be investigated promptly to avoid secondary damage or deterioration to other parts of the system.
