Water purity is a big challenge today. Often soil, moss and fine impurities get accumulated in plastic or concrete tanks kept on the roofs of houses. Therefore it is very important to clean it. There is a risk of infection due to not cleaning the water tank. In such a situation, people adopt various measures to clean the water tank. In such a situation, you must have seen many times that people also put alum in the water tank. But do you know what happens by putting alum in the water tank? Here we are going to tell you why alum should be added to the water tank. Let us know.
1. Purification of water
The most important function of alum is to settle down the soil and dust particles present in water. In the language of science it is called ‘coagulation’. When you put alum in the tank, it sticks to the fine dirt particles floating in the water, causing them to become heavy and settle at the bottom of the tank. The water above this becomes completely clear.
2. Get rid of bacteria and germs
Alum has anti-bacterial properties. Although it does not completely sterilize water like chlorine, it is helpful in reducing the number of harmful bacteria growing in water. If the quality of water in your area is poor or there is a slight odor from the water, then the use of alum can prove to be excellent.
3. Prevent algae from forming
During the summer season, due to sunlight, green algae often accumulates in the water tank. This moss not only makes the water dirty, but can also clog the pipeline. The use of alum slows down the process of algae accumulation on the walls of the tank, due to which the tank remains clean for a long time and the water does not become dirty.
4. Beneficial for skin and hair
Bathing with salt water can cause skin itching, rashes and hair loss. Alum reduces the salinity of water. Bathing with alum water helps in deeply cleansing the skin. Besides this, bathing with this water also prevents the smell of sweat.
Correct way to use alum
Add about 50 to 100 grams of alum for a 500 liter tank. For this, take a big piece of alum and tie it in a cotton cloth or bundle. Hang this bundle in the middle of the tank with the help of a long rope. Leave it in water overnight. By morning all the dirt will settle to the bottom.
