What Does Reverse Osmosis Do?

March 19, 2020 4:14 pm Published by Leave your thoughts

The process of reverse osmosis is relatively simple, which is why it’s a common choice in systems people use for water filtration. It occurs when water pressure pushes tap water through a semipermeable membrane to remove water impurities. By this process, dissolved inorganic matter found in water, such as salts and minerals, can be removed from the water to make it “softer.” This technology has been used by municipalities since the late 1970s, and it has become increasingly popular among residential consumers since then as well.

So, what happens to the impurities that are to be filtered out? Below, we’ll cover this and some other key reverse osmosis facts in Shelby County, OH. Ultimately, the material gets filtered out and flushed down the drain, simply leaving behind clean drinking water that tastes better than water that is laden with too many minerals.

What are the parts of a reverse osmosis system?

There are several basic components of a reverse osmosis system, including the following:

  • Cold water line valves: This is the valve that connects to the cold water supply line. It features a tube that connects to the inlet side of the reverse osmosis pre-filter. This part serves as the RO system’s water source.
  • Pre-filters: Water that enters through the cold water supply line comes first into the system’s pre-filter. A reverse osmosis system may contain more than one pre-filter, and those filters are likely to be sediment or carbon filters. They protect the RO membranes by removing debris that could otherwise clog up the system, and can also remove chlorine that can damage the RO membranes.
  • Membrane: The membrane is perhaps the most important part of the system, as it is the part that removes the largest number of contaminants, whether they’re health risks or purely aesthetic. After water passes through the membrane, it goes into a pressurized storage tank.
  • Post-filters: After the water leaves the storage tank and before it comes out the faucet, it gets treated one more time in a post-filter, usually a carbon filter. It’s at this point that any remaining foul odors or tastes are removed.
  • Check valve: The outlet end of the RO membrane’s housing will have a check valve, which prevents backflow of treated water from the RO storage tank. Without a check valve, this backflow could result in the RO membrane getting damaged.
  • Flow restrictor: Water that passes through the RO membrane must be controlled by a flow restrictor, which maintains the proper flow rate needed to get the highest quality drinking water after filtration. This also helps keep pressure down on the inlet side of the membrane to prevent damage to that part.
  • Storage tank: The RO storage tank can hold anywhere from two to four gallons of water, depending on the model. The bladder in the tank will keep the water pressurized when full.
