Today, a lot of the world’s water is purified using reverse osmosis. Even though reverse osmosis is proven to work, there still is the possibility of finding a cheaper and more environmentally friendly alternative. This is where using nano-materials comes in. With several studies currently underway with positive results, nano-materials may soon be used as publicly as reverse osmosis.

Key Takeaways:

• While reverse osmosis technology is preferred today to supply people with safe drinking water, experts suggest that purifying water by exposing it to nanomaterials could offer a cheaper and cleaner alternative in the future.
• Water so purified could be made available to the public at a price as low as three or four paise per litre, say experts.
• “The criteria with RO is the quality of water that is purified. The concept is to expose water to nano silver and not release the particles.
