As per a report by WaterAid, a non-profit organisation, around 78 million people in India don’t have access to clean water. The climate change coupled with the increasing population of the country could only increase this number in the future.
But thanks to the modern technologies, simplified water purification systems are now easily available at affordable prices. However, the seriousness of this problem is such that water purification is now a growing concern among scientists and experts. Let us have a look at how we are preparing to tackle this problem in the future.
Nanotechnology water purification
While there are many modern purification technologies like RO water purifier, nanotechnology is considered to be one of the greatest innovations. A few years ago, the Indian Institute of Technology developed the cheapest nanoparticle filtration system. While affordable purifiers are not new, this purifier can effectively eliminate components like arsenic and lead from water. In 2015, the Union Ministry of Drinking Water and Sanitation recommended replicating and using this purifier in all the Indian states that suffer from arsenic contamination.
Eliminating chlorine by-products from water
One of the rising concerns of the water purification industry is the existence of chlorine by-products in water. The problem is quite common in several Indian cities, and this is one issue that is sure to have a great impact on the purification technologies in the future. The presence of the byproducts is known to create THMs (Trihalomethanes) like chloroform which can cause respiratory disease. This is the reason why shower filters are often recommended in areas where chlorine byproducts exist in water. In the future, the use of such by-products to purify water would probably be restricted.
Increasing number of start-ups
With the growing interest in water purification, even the number of start-ups tackling this problem is on the rise. There are now a number of new companies that offer innovative and affordable purification systems like RO water purifier and purifiers that use advanced purification technologies.
Even the market leaders in this segment now offer an extensive range of purifiers which can be easily installed in homes to provide them with easy access to clean water. Moreover, many large corporations in the country are now focusing on matters like water recycling and conservation.
Desalination helps extract mineral components from saline water. There is an increasing shortage of water even for daily uses. Due to the increasing water security problems, even the desalination technology is now an important consideration. For instance, Tamil Nadu is about to set up the country’s first offshore desalination plant soon.
Unlike other desalination plants which use reverse osmosis technology, this plant will use LTTD (Low-Temperature Thermal Desalination) technology which is developed indigenously and is also eco-friendly. Similar projects are now being considered by many other states in the country.
Around 18% of the world’s population resides in India, but has only 4% of the world’s freshwater resources which too is significantly declining in quality and quantity. While drinking water was considered safe in the past in India, providing 1.3 billion people access to clean drinking water is a major challenge. Technology is already playing an integral role and would continue to improve the purification technologies in future as well to create simple and affordable ways to provide clean drinking water to the country.
