It can be seen that there are many wastes generated from different sources and polluting different water sources. All of the sources are mainly created because of the different activities of humans. So, it can be noticed that there is a high demand for pure water that can be used for different purposes. The best way out of this is to treat water for making it pure. Although it can be noted that the different traditional methods of water purification are not effective anymore. It is because the severity of the waste & pollutants has also changed. So, there is a need for the introduction of new methods that can be used for the purpose of purifying water more effectively. In this project, the description of the views of the different scholars regarding these technologies was described. Moreover, the need for different methods along with thor method of preparation was also described. The recommendations for the betterment of the current research are also presented here
