Desalination

Clean, safe drinking water is scarce. Today, nearly 1 billion people in the developing world don't have access to it. Yet, we take it for granted, we waste it, and we even pay too much to drink it from little plastic bottles.

Water is the foundation of life. And still today, all around the world, far too many people spend their entire day searching for it.It’s hard for most of us to imagine that clean, safe water is not something that can be taken for granted. But, in the developing world, finding a reliable source of safe water is often time-consuming and expensive. This is known as economic scarcity. Water can be found...it simply requires more resources to do itIn other areas, the lack of water is a more profound problem. There simply isn't enough. That is known as physical scarcity.

The problem of water scarcity is a growing one. As more people put ever-increasing demands on limited supplies, the cost and effort to build or even maintain access to water will increase. And water's importance to political and social stability will only grow with the crisis.   To come over from the water crisis desalination is the best solution to solve the water scarcity.

Desalination is a process that removes minerals from saline water. More generally, desalination refers to the removal of salts and minerals from a target substance, as in soil desalination, which is an issue for agriculture. Saltwater is desalinated to produce water suitable for human consumption or irrigation.The different methods of desalination are Membrane desalination, Reverse osmosis, and Electro dialysis.

Our students have inculcated about the process of desalination to convert salt water as to potable water.The students have visited STP at our school and Desalination plant at Chennai.They thoroughly enjoyed the session and they had indeed experience about the process and they also understood the process to obtain fresh water from desalination and how sewage water is treated using STP.
