Methods of Purification of Water Project Class 11

There are several methods for water purification. Some are natural and others are man-made. The former can be a great option in areas where magnewsworld surface water is prone to contamination. Pretreatment removes chemical and biological contaminants from water before it is used for human consumption. Pretreatment methods include screening to remove large numega debris and chemicals that control bacteria. Sand filtration can also be used to reduce the amount of suspended solids in water.

Another effective method of water purification is boiling. Boiling water kills bacteria and viruses by forcing them to dissipate at a high temperature. It also kills chemical additions. However, boiling water does not completely remove all impurities. After craftymagazines boiling, water should be allowed to cool before it can be consumed.

In many regions, fluoride is added to the water supply. But too much fluoride can be harmful to humans and can have a negative impact on their health. To reduce fluoride levels, filters with vitlink activated alumina or bone char are used. Other methods for purification of water include distillation and reverse osmosis.

Students learn the processes of water purification and use real-life situations to apply these skills. They learn about the methods used by justspine environmental engineers to make potable water. They also learn about the techniques used by Mrs Peers-Dent to purify seawater. In addition, they are also exposed to the testing methods used by analytical chemists at Thames Water.
