What is Reverse Osmosis Water Filtration?

What is Osmosis?

When two salt solutions of different concentration are separated by a semi-permeable membrane. Water will move through the membrane from the weaker solution to the stronger solution until the solutions are of the same salt concentration.

What is Reverse Osmosis?

In reverse osmosis system, the process of osmosis is revered by applying pressure. Water is forced to move from a higher concentration solution to the weaker solution. As the membrane is porous, it allows water to pass through but stops bigger salt particles. Thus separates water from salts.

Pros of Reverse Osmosis

  • Reverse Osmosis removes a major part of harmful contaminants from the water. It can remove 95 to 99 percent of Total Dissolved Salts (TDS) along with chlorine and fluoride from water.
  • Reverse Osmosis improves the appearance, taste, and odor of water.
  • It is a safe and tested method to process water. It is widely used in industry, the bottled water you drink is actually reverse osmosis water.
  • The porous membrane of the RO plant is a defense wall against most of the harmful bacteria and pathogens. So reverse osmosis is really effective at desalinating water and providing mineral-free water.
  • RO plant also filters out almost all metals and minerals dissolved in the water.
  • Reverse Osmosis is a cheaper and cost-effective way to purify water and its an energy efficient way to filter water.
  • Installing an RO filter at home will provide clean and safe water for drinking and cooking and will improve the health of your family members.
  • Maintenance of an RO water filter is quite easy.


Cons of Reverse Osmosis

There are several downsides of RO water filtration plant.

  • Reverse Osmosis also removes healthy and natural minerals from water along with harmful bacteria and pathogens.
  • Though Reverse Osmosis removes a major part of impurities from water. But some chemicals and contaminations have smaller molecular size than water. So the porous membrane is unable to filter them.
  • Water wastage is a major drawback of RO plants. According to estimates for every one gallon of treated water three gallons of water is wasted.
  • The initial cost of the RO plant is high.
  • For better performance, you have to maintain your RO plant regularly. The small pores of the RO system can be clogged easily.
  • After installing an RO filter in your home, you have to replace the filters regularly for better performance.
  • The process of Reverse Osmosis is slow and takes time. In household RO plant, filtration is done by using water to push tap water through filters and it’s a slow process. If you have used the system’s holding tank then you have to wait for RO plant to filter more water.

Conclusion

Look at both sides of the picture and decide yourself. Everything has its Pros and Cons. Though a lot of water is wasted in the process and there are other drawbacks too. But what else is important than clean drinking water? In my opinion, you should have an RO plant in your home to have an endless supply of clean drinking water for you and your family.
