What is Reverse Osmosis Water Purification?

The Pure Water Systems Blog

A reverse osmosis (RO) water purification system is a valuable investment for you and your family to enjoy healthy, great tasting purified water at the turn of a tap in your own home. Not only is a reverse osmosis system one of the most advanced and effective household water purification methods, most reverse osmosis systems do not need any electricity to operate.

How does reverse osmosis water purification work?

Firstly, the reverse osmosis water purification system filters the water through carbon cartridges, removing chlorine and sediment.

Next is the purification stage, where the water is pushed through a fine reverse osmosis membrane, designed to remove almost all contaminants including lead, total dissolved solids (such as fluoride), recycled sewage water and more. Finally, water then flows through another carbon cartridge to polish the water before it flows through your tap. 

What are some of the contaminants a reverse osmosis system can remove?

  • Copper 98.5%
  • Fluoride 93.6%
  • Arsenic 88.0%
  • Barium 96.3%
  • Selenium 97.9%
  • Total Dissolved Solids Reduction 90.8%
  • Cadmium 99.1%
  • Lead 98.6%
  • Chromium Cr 6 96.4%
  • Turbidity 99.1%
  • Chlorine 95%

Commonly asked questions:

Why are reverse osmosis systems popular?

Reverse osmosis is the ultimate in water filtration. This intense purifying process provides the high quality, fresh, purified water conveniently at the turn of a tap.

Are reverse osmosis systems noisy?

No, our reverse osmosis systems are not noisy. Systems do have a slight sound, which can be heard when water is being processed.

What are the health risks of drinking reverse osmosis purified water?

While reverse osmosis is excellent for removing contaminants (such as heavy metals like cadmium, arsenic and chromium), healthy minerals and salts can also be removed leaving your water acidic. For great potential health benefits (such as improved gut and kidney health), you can raise your water’s pH balance to a level considered alkaline by adding healthy minerals back to your water with a Remineraliser cartridge.

How long will a reverse osmosis system last?

Our reverse osmosis systems are made of the highest quality parts and fittings for minimal future maintenance. The cartridges should be replaced every 12 months, but may need to be replaced earlier depending on your water quality and use. The membrane replacement is periodically depending on water quality and use also. Please speak to a friendly team member to confirm the estimated lifespan of the system you are considering. 

Is reverse osmosis water purification bad for the environment?

Switching to a reverse osmosis system for great tasting, healthy, purified water instead of purchasing plastic water bottles is a environmentally friendly alternative, as single use plastic is hazardous to our environment. Most reverse osmosis systems don’t require electricity to run. Some reverse osmosis systems can waste up to two-thirds of your water, however our Eco Hero 50 membrane provides up to 300% improved water efficiency.

What are the health benefits of the reverse osmosis?

General tap water can contain Volatile Organic Compounds (VOCs) such as pesticides and herbicides, heavy metals, endocrine disrupting chemicals such as fluoride, as well as hormones and cysts.

Using a reverse osmosis will reduce all of these contaminants significantly, protecting your body from absorbing them.
