Research Overview

According to United Nations, around 2.2 billion people globally lack proper access to safe water services and another 2 billion people live in countries witnessing high water stress resulting in considerable number of fatalities due to water borne diseases, inadequate water purification, and lack of hygiene. Improving water utilities, and enhancing water purification technologies is the need of the hour which results in a positive impact on human health. Additionally, selection of the most efficient water purification system is very important as the water quality characteristics changes with the water source available in the respected locality and a ‘one-size-fits-all’ solution for domestic water purification cannot be adopted across the globe. Therefore, selection of an efficient domestic water purification system warrants the immediate need to increase focus on low cost and energy efficient water purification technologies to supply freshwater and reduce the negative impacts of waterborne diseases on human health and environment.

With membrane and UV radiation based water purification systems holding the lion's share of the global domestic water purification market (i.e. upto 90 %), researchers and stakeholders believe that technological advancements facilitating membrane permeability and high conversion is required for more adoption of these technologies even in remote locations. Innovations which facilitates the integration of artificial intelligence, machine learning and smart sensors is also necessary to increase performance efficiency and to enhance the market growth of domestic water purifiers.
