Alternative Methods for Chemical Disinfection of Potable Water

Microbial contamination in drinking water proves to be a sustainable threat to human health. Several methods are being utilized for disinfecting contaminated drinking water varies from simple boiling method to advanced technologies such as membrane technologies (Micro filtration, Ultra filtration, Reverse osmosis). Various chemical methods practiced are chlorination, ozone, hydrogen peroxide, iodine, bromine, and peracetic acid treatment. Chemical disinfectants lead to formation of toxic by-product which degrade the quality of water. The present review paper discusses alternative methods for chemical disinfection of potable water.
