How Reverse Osmosis System Work

Many of you might thing that reverse osmosis system is a complex system, but it is really rather simple and straightforward process of water filtration. Reverse osmosis is also not a brand new system. In fact, it had already been utilized for many years in order to desalinate water. By knowing what it does and how it works, it will reduce the mystery and confusion you may feel about it. This way, you can also enhance your knowledge about water filtration.

In understanding what reverse osmosis systems are, there are some points for you to remember. Reverse osmosis systems all work the same way and most of them look alike. They also have the same basic components with the only real difference being the quality of the membranes and filers inside of the system.

How Does Reverse Osmosis System Work?

The reverse osmosis system works by dissolving the inorganic solids like salts from water. The system does it by the water being pushed a household water pressure via a semi permeable membrane. This membrane only allows the water to cross and not the impurities or any contaminates. Instead, contaminates and impurities gets flushed down the drain.

Benefits

Some of the benefits of reverse osmosis system include:

  • Pure, clean drinking water
  • Removes unwanted tastes and odors from water
  • Consumes no energy
  • Completely convenient
  • Flushes away contaminates and impurities
  • Low production cost
  • Minimal maintenance

Basic Components of Reverse Osmosis System

The most common components to all reverse osmosis systems are:

  • Cold water line controller – the valves used to fit onto the supply line for cold water. It comes with a tube attaching itself to the RO pre-filter’s inlet side. It acts as the water source for the system.
  • Pre-filter – Where the water supply first enters in the reverse osmosis system. Most common used pre-filters are sediment filters used to remove dirt, sand, silt and other forms of sediments. Carbon filters can also be used to remove chlorine.
  • Reverse osmosis sheath – Acts as the heart of the entire system with the spiral wound being commonly used. It offers two options: CTA or cellulose tri-acetate known as chlorine tolerant and TFC or tinny film composite, not chlorine tolerant.
  • Post filter – When the water leaves the storage bank, it goes through the post filter before it goes to RO faucet. It removes any remaining odors and tastes from the product water through post filtration.
  • Automatic shut-off regulator – The automatic valve is used to conserve water. If the storage tank is already full, it shuts off the valve to stop water production.
  • Check valve – Prevents backflow from the storage reservoir that can rupture the membrane.
  • Storage tank – Standard tank can hold up to 2 and half gallons of water.
  • Faucet – The system uses its own faucet that is installed usually in the kitchen.
  • Drain line – The line used in disposing contaminates and impurities from the tap water.

These are basic information to know about reverse osmosis system. With this, you will be able to understand how tap water is effectively cleaned and purified through reverse osmosis. You will be able to understand exactly how residential filtration system works.
