**Describe the steps involved in getting clarified water from wastewater. **
Answer:
The steps involved in getting clarified water from wastewater are:

  • Aerator is used 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.
  • 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.
    Then any disinfectant such as chlorine tablet is added to the filtrate and stirred to obtain completely clear water.
