The specific design and operation of an ETP will depend on the type and quality of the wastewater being treated. However, most ETPs include a series of treatment stages, such as:
• Physical treatment: This may include processes such as screening and sedimentation to remove large particles and debris from the wastewater.
• Chemical treatment: This may include processes such as pH adjustment and coagulation to remove dissolved pollutants.
• Biological treatment: This may include processes such as aeration and activated sludge treatment to remove organic pollutants through the action of microorganisms.
• Disinfection: This may include processes such as chlorination or UV treatment to kill harmful microorganisms in the wastewater.
