Hygienic, disinfected, and accessible water for all people is an essential requirement of the world. However, bad economics and poor water utility infrastructure and outdated purification and treatment technologies have resulted in the spread of waterborne epidemics and also fatal cases. Inadequate clean drinking water supply and hygiene should hence be provided to all people through novel innovations in the current set of water purification technologies. Water purification technologies functions by removing the contaminants from the drinking water supply to extremely low levels and the technologies can also specifically focus on removing a broad spectrum of micro-contaminants from the water supply. The purification process of eliminating undesirable toxic chemicals, biological contaminants, and suspended solids also depends upon the stringent regulations formulated by governmental organizations. The regulations will determine the standards of the drinking water quality and the main aim of the water purification processes is to remove the micropollutants, ions, and dissolved substances from the water sources apart from removing the microbial contaminants and other physically visible impurities.

This research study identifies the need for innovations in water purification technologies and how technological advancements in the water purification and generation sector can aid in mitigating challenges with existing water treatment and purification methods. The research service offers insights primarily on the following: Overview of Water Purification Technologies , Drivers and Challenges in Water Purification, Key Innovations and Strategic Insights and Recommendations
