Water water everywhere, yet not a single drop to drink!
Though the above lines still live to be one of the greatest epitomes in literature, they hold true as a growing, dreadful and tormenting fear in humanity. Drinking water scarcity is not something new to us, yet it is something that still needs to be resolved urgently.
Various innovative methods are being implemented globally to overcome the scarcity of drinking water. One of the most effective and efficient methods of water purification, that is making a great impact in and around the world is ‘Solar Powered Water Purification’. Unlike other chemical methods, the uses and benefits of this method are significant, notable and relevant. There are various reasons that make solar power one of the most efficient and adequate choices for water purification. It is the fastest and go-to option at times of calamities and natural disasters. It is an inexhaustible power source with very few adverse effects on the environment.
There are multiple processes for water purification that are used on different scales in different parts of the world. Solar Water Disinfection (SODIS) is one of the most simple and easily accessible forms of purification. The contaminated water is exposed to UV rays from sunlight for 6 hours in a colourless plastic bottle (PET bottle) or glass bottle. This kills the microorganisms present in the water. This is one of the cheapest and the most accessible methods of water purification, which requires only sunlight and bottles.
Solar Distillation is another effective method for water purification that, compared to SODIS, has to be implemented on a much larger scale. The system consists of three components: the solar energy collector, the distillation system and the solar water disinfection system. The water is first vaporized and later condensed for collection, removing all solid impurities from it. This is a very effective method for converting sea water into drinking water.
Another method for water purification is Solar Water Pasteurization which involves moderate heat, which is provided through cookers that use solar energy. The heat kills the viruses and bacteria that are present in the water, thereby making it potable.
Solar Water Purification is processed through the electricity generated from solar powered batteries. It generates power for the filtration and purification of water. The batteries are mobile and can be helpful especially at times of disasters. These structures are of different sizes that can work for small scale and large scales processes.
Keeping apart the cost-effectiveness of solar power, there are many other reasons that make it a more apt choice. One of the major benefits of solar water purification is that it does not involve any sort of chemical components. The purification process involves exposure to UV rays and for this reason, there is no change in the taste of the water and it also increases the microbiological quality of water. The SODIS process is a process that can be effective at the household level. When compared to other methods, the side effects of the solar-powered processes are less hazardous to the environment.
Rite Water Solutions has taken various steps in implementing Solar powered water purification process in various parts of India. We have made water purification budget friendly in many rural areas where electricity is a precious source. Powering the plants with solar panels have reduced the cost and made it affordable for the people. Powering solar based purification systems has not only improved cost efficiency but also provided access to a safe and healthy lifestyle.
