Questions & Step-by-Step Solutions

Which process is primarily used to remove suspended solids from wastewater?
  • Step 1: Wastewater is collected in a large tank.
  • Step 2: The tank is allowed to sit still for a period of time.
  • Step 3: During this time, heavier particles (suspended solids) in the wastewater start to sink to the bottom of the tank.
  • Step 4: The settled solids form a layer at the bottom of the tank, while clearer water remains on top.
  • Step 5: The clear water can then be removed from the top, leaving the solids behind.
