Clean water for rural by using solar power

Till date in many rural parts of India people still find it difficult to get pure water for drinking purposes. They undergo boiling process which is even sometimes difficult.The major percent of health issues come up in rural is due to unsafe drinking water.

Many projects, seminar, talk shows took place in different part of villages across the country to bring awareness on using clean and pure water for drinking and cooking purposes. Things fail as these areas lack safe and pure water availability.

To resolve this a new technology has been invented to clean water at a much cheaper price. An MIT-designed solar-powered water purificationsystem .The reverse osmosis system consists of two photovoltaic solar panels that power a set of pumps that push both brackish well water and collected rain water through semiporous membranes that filter and purify the water. The system produces about 1,000 liters of clean water a day for the village’s 450 residents.

“When you live in a very rural area, you have to do everything yourself," said MIT researcher Huda Elasaad. "Farming, if there’s something wrong with your well, you’re the one stuck fixing it, because no one’s going to drive into the jungle to help you. So they were very handy, which made it easy for us to train them."

The residents can easily learned how to operate and maintain the technology by themselves. Daily upkeep ranges from changing out ultraviolet lights and filters to testing the water quality and replacing batteries. They get in touch with local suppliers when they need new parts.

The researchers are also excited about the village’s new source of income, but they’re equally interested to see what effect the system has on the resident’s health. Before the system, people couldn’t afford clean water, but they could afford soda, which was cheaper. Where children and adults were drinking soda daily, now you see water replacing soda, a shift that will surely have many positive outcomes.

Since the system has proven to be one that can be operated by non-experts with just a little training, the MIT team is ready to distribute it to more areas where clean water is scarce. The researchers say that the system is adaptable to communities in rural villages as well as crowded cities. It can be used with different sources of water and levels of water quality and can be tweaked to work as a reverse osmosis, nanofiltration or elecrtrodialysis system depending on the area’s needs.

The technology could bring cheap clean water to hospitals, schools, hotels and more to help boost the health and wealth in these areas.
