A clean, constant supply of drinking water is essential to every community. People frequently drink water that comes from surface water sources, such as lakes, rivers, and reservoirs.

Most water suppliers add disinfectant to kill bacteria and other germs. One of the disinfection methods is ozonation.

The primary objective for this project is to study the process employed by ozonation to treat potable water. So, the information on ozonation is being found out and explained in this project. The advantages and disadvantages of ozonation are compared with some other disinfection methods especially chlorination. The information provided is aims to imposed knowledgs in water treatment by ozonation process.
