Whether you are looking for a home parts of ro water purifier, or a commercial RO system, there are numerous components to consider. If you want to select a good RO system, you must first understand how each of these components works.

The RO Membrane is the most important component of a reverse osmosis water purifier. This is the section responsible for removing dissolved solids, salts, and minerals from water. There are several types of semipermeable membranes. The thin-film composite polyamide (TFC) membrane is the most commonly used in RO filters.
