What is Reverse Osmosis?

Reverse Osmosis is a process used to remove contaminants from water by pushing the water under pressure through a semi-permeable membrane.

A semi-permeable membrane allows molecules to pass through but holds contaminants. Consider a screen door, the mesh blocks flying insects, airborne debris while allows air to pass through it.

 

How does Reverse Osmosis Work? Understand Osmosis to Understand Reverse Osmosis

Osmosis is naturally occurring phenomenon – process where molecules pass through from less concentrated solution to strong concentrated solution. For instance, plant roots absorbing water from soil or human organ kidney drawing water from blood.

Let’s discuss some more examples of Osmosis from real life to grab the concept. Notice the fingers gets wrinkly after water bath, the skin of fingers absorb water and get expanded due to osmosis. Another example, why you feel thirst after eating salty food ? Because the cells in the body become concentrated with salt, so they absorb the water and cause us to feel thirst.

In Reverse Osmosis process pressure is applied to force the water move from high concentration towards lower, leaving dissolved salts behind the membrane only allowing water molecules to pass through it.

This water which passes through the membrane is called permeate or product water. Usually 99% of the dissolved salts can be removed from this reverse osmosis (RO) process.

Figure explains the concept of Osmosis & Reverse Osmosis –  the water with the lower concentration would naturally move towards the water with the higher concentration of solvent in Osmosis and process would be completely reversed by applying external pressure in Reverse Osmosis. You can try this experiment at home mixing salt in water, separating it with membrane.

 

What Contaminants Does Reverse Osmosis Remove?

Reverse osmosis can remove up to 99% of dissolved salts, suspended particles, organics, as well as bacteria from water.

RO is being widely used to produce highly purified water for drinking water systems, industrial boilers, pharmaceutical, food and beverage processing, cosmetics and many other applications.

Domestic water purifiers using reverse osmosis technology to purify drinking water needs, RO truly is the purest choice for any home. >>Need Help Selecting the Best Water Purifier for Kitchen ?

 

Is Reverse Osmosis Water Safe to Drink?

RO water is clean and healthy – the reverse osmosis treatment is currently the best to remove most of the contaminants which other water treatments can’t.

Normal tap water does contain small amount of essential minerals but contains numerous contaminants too. Yes, reverse osmosis filters out minerals but consuming mineral-free purified water is not harmful and mostly our minerals intake needs are met via the food we eat. Health study also reveals that human body obtains majority of minerals from food and not from drinking water.

 

Conclusion

Reverse osmosis treatment is currently the best to remove contaminants from drinking water. Reverse osmosis can remove up to 99% of dissolved salts, suspended particles, organics, as well as bacteria. RO water is clean, healthy and having benefits far outweigh any minor objection.

Reverse osmosis water has improved water taste, you can improve the taste of your coffee, drinks and cooking. You’ll stop buying bottled water if using RO filter at home.

    Its like you read my mind! You seem to know so much about this, like you wrote the book in it or something. I think that you could do with some pics to drive the message home a bit, but instead of that, this is great blog. A fantastic read. I’ll definitely be back.
