A review on purification of water for drinking purpose in rural areas using electrochemistry process

Abstract

A study on various contaminants present in the water bodies basically in the rural areas is made by collecting various sources and data and then finally using electrochemical method to improve the hygienic quality of impure water both for industry and drinking purpose. This step connects between physical chemistry and electronic science which is also known as electrochemistry which is proved to be a tool which is clean, versatile and powerful for the development of new advanced methods for water purification. This electro-assisted process is used for water purification because it is unlike from the other well-built technologies. The pressure-driven membrane-based methods consists of process like microfiltration, reverse osmosis, biological treatment, ultra-filtration, treatment of water by means of various chemicals such as chlorine or ozone, and treatment with UV. As this method gives the freedom of choice in adjusting the electrode potential and electrode material to meet almost any demand it is extremely flexible and selective. This study focuses on recent developments in the field of electrochemical technologies for drinking water mainly and also waste water treatment
