Membrane Based Seawater Desalinationby Reverse Osmosis Reverse Osmosis | Seawater Desalination
The world has been using seawater desalination technology for a long time. A decade ago, major desalination plants used seawater and used thermal energy to get drinking water for millions of people together. This traditional method was effective, however, came with poor efficiency. The amount of energy required to boil water and then condense the vapors was far too much. Recently, this method has been replaced by membrane-based reverse osmosis that is now being used by some of the major industries as well as countries for providing clean and safe drinking water to their people. This method has replaced the previous one with better efficiency and output. But what lies ahead in for this technology is something to look out for.
The technology which is also known as SWRO is facing a bigger challenge and opposition due to its high unit installation costs and energy requirements. Not only this but the amount of pollution caused by the rejected water is one aspect to think about. This causes harm to the marine life as well as the atmosphere with its GHG emissions. This can, however, not be replaced by another option, at least not for another decade considering quite a big amount of the world population lives near the seas. This makes the oceans a vast and practically abundant resource at our hands. Today
have more than 18,000 desalination plants around the world of which more than
half operate on RO technology.
pollution caused by the method and its ill effects are being currently studied across all the world to make it better
and sustainable each day.
SWRO is seeing a major transformation in
the kind of method, membrane technology, process and more to make it more eco-friendly.
efforts have resulted in some of the most promising discoveries in the past few
- Future Prospects:
Being mindful of the requirements that future requires for us, the major discoveries made have set a path for us to work upon. It requires for us to use SWRO as a conventional technology and work towards making it as efficient, productive and green as possible. We wouldn’t want to be faced with either a water crisis or global environment problem. Which brings us to the future prospects of this.
a vision in mind, careful studies are now approaching this topic from different
angles. To make the method more efficient, Graphene sieves, membrane tech, and more changes are being suggested in
the current method.
membranes, high ultra-permeability with emerging processes is being now looked
emerging processes look at the problem from a very different perspective of
base method. These can include, membrane distillation, pressure induced or
retarded osmosis, forward osmosis, reverse electrolysis
SWRO technologies hold more importance to us in the water filtration history than ever before. With its proved effectiveness, the only thing that remains in front of us to make it as eco-friendly and sustainable as possible. This is so that if we do not find another method of filtration, this will be our salvation for a long time to come.
