How Does an Reverse Osmosis System Work?

What is Reverse Osmosis?

Reverse osmosis removes pollutants from unfiltered water or feed water by forcing water through a semipermeable membrane. Water flows from the more concentrated side of the RO membrane, which has more contaminants, to the less concentrated side, which has less contaminants, to produce clean drinking water. The fresh water produced is known as permeate. The term for the leftover concentrated water is waste or brine.

Small pores in a semipermeable membrane allow water molecules to pass through while blocking pollutants. To achieve equilibrium on both sides, water concentrates as it moves across the membrane in osmosis. However, reverse osmosis prevents pollutants from getting through to the side of the membrane that is less concentrated. For instance, during reverse osmosis, pressure is applied to a volume of saltwater, and only pure water passes through while the salt is left behind.

How Does a Reverse Osmosis System Work?

Before pushing water through a semipermeable membrane to remove dissolved solids, a reverse osmosis system filters out sediment and chlorine with a prefilter. After leaving the RO membrane, drinking water is refined by a postfilter before entering a special faucet. Reverse osmosis systems progress through various stages depending on the number of prefilters and postfilters used.

RO System’s Working Stage

The major component of a reverse osmosis system is the RO membrane, although it also comprises other filters. There are 3, 4, or 5 filtration stages in a RO system.

In addition to the RO membrane, every reverse osmosis water system also includes a sediment filter and a carbon filter. The filters are classified as prefilters or postfilters based on whether they are employed before or after the membrane.

Each system type includes one or more of the following filters:

Reduces impurities including rust, dust, and dirt using a sediment filter.

Reduces chlorine, volatile organic compounds (VOCs), and other impurities that give water an unpleasant taste or odour thanks to the carbon filter

Semi-permeable membrane removes up to 98% of all dissolved solids (TDS)


Through the RO membrane, a reverse osmosis system eliminates dissolved solids like arsenic and fluoride. For a wide range of reduction, a RO system also has sediment and carbon filtering. In a RO system, the sediment filter eliminates dirt and debris, and the carbon filters remove chlorine, bad tastes, and odours.
