hey friend ️️here is your answer

The steps involved in getting clarified water from wastewater are as follows:


(i)Use an aerator to bubble air through the wastewater. A mechanical stirrer or a mixer can also be used in place of the aerator. This helps in reducing bad odour of the wastewater.
(ii)Then, the water is filtered through the layers of sand, fine gravel, and medium gravel. Filtration makes the wastewater clean from various types of pollutants. The water is filtered continuously until it becomes clear.
(iii)Then any disinfectant such as chlorine tablet is added to the filtrate and stirred to obtain completely clear water.

Hey!
Ur answer is ;-
These are the steps involved in the purification of water,
1. In the first step, all the physical impurities like stones, plastic bags ,cans etc. are removed by passing the water through screens.
2. Now, water is subjected to sedimentation where impurities are removed by the force of gravity.
3. Solids settled at the bottom of the sedimentation tank is removed. This is called sludge.
4. An aerator cleanses the water from other impurities.
5.Chlorination is done to remove all disease causing bacteria.
