In the treatment of waste water, following steps are involved.(i) aera...
Aeration:
The first step in the treatment of waste water is aeration. Aeration is the process of adding air or oxygen to the water. This is done to increase the level of dissolved oxygen in the water, which is important for the survival of aerobic bacteria. Aerobic bacteria play a key role in the treatment of waste water as they break down organic matter and pollutants.
Nitration:
The second step in the treatment of waste water is nitration. Nitration is the process of converting ammonia (NH3) into nitrate (NO3-) through biological oxidation. This process is carried out by nitrifying bacteria. Nitration is important as it helps to remove nitrogen compounds from the waste water, which can be harmful to the environment.
Chlorination:
The final step in the treatment of waste water is chlorination. Chlorination is the process of adding chlorine or chlorine compounds to the water. This is done to disinfect the water and kill any remaining bacteria, viruses, and other microorganisms that may be present. Chlorination is an important step in the treatment of waste water as it helps to ensure that the water is safe for reuse or discharge into the environment.
Correct Order:
The correct order of these steps is (i) aeration, (ii) nitration, (iii) chlorination.
The waste water is first subjected to aeration to increase the level of dissolved oxygen. This promotes the growth of aerobic bacteria, which help in breaking down organic matter and pollutants.
Next, the waste water undergoes nitration, where nitrifying bacteria convert ammonia into nitrate. This helps in the removal of nitrogen compounds from the waste water.
Finally, the waste water is treated with chlorine or chlorine compounds in the process of chlorination. This disinfects the water and kills any remaining microorganisms, ensuring that the water is safe for reuse or discharge.
Therefore, the correct order of the steps involved in the treatment of waste water is (i) aeration, (ii) nitration, (iii) chlorination.
