Whether you're looking for a home RO water purifier or a commercial RO system, there are many different parts to consider. If you want to choose a good RO system, it's important to understand how each of these parts works.

The RO Membrane is the main part of a reverse osmosis water purifier. This is the part that removes dissolved solids, salts, and minerals from water. Several types of semipermeable membranes are available. The most common type used in RO filters is the thin-film composite polyamide (TFC) membrane.

The membrane is usually protected by a pressure regulating valve. A valve on the drain line can also help control the flow of water through the membrane. A RO membrane will need to be replaced about every two to four years.

In addition to the membrane, other parts of an RO system include a sediment filter, a carbon filter, and a post filter. A post filter is used to remove organic particles, chlorine, colour, and odor. It's important to replace these parts as often as needed.

Other parts of a RO water purifier include the drain line, which is used to drain impure water. There are also valves, such as the drain saddle, inlet saddle, and pressure regulating valve. Faucets are also included. Faucets are lined with plastic material so they don't corrode in the RO water.

Another important part of an RO water purifier is a high-quality stainless steel tank. The tank should be free of other compounds.
