Wastewater treatment is the process of removing contaminants from wastewater and converting it into an effluent that can be safely discharged into the environment or reused for various purposes. The process involves physical, chemical, and biological processes that remove physical, chemical, and biological matter that contaminates the wastewater. The sewage treatment plant treats all of the collected sewage water. Before wastewater is discharged into water reservoirs, it goes through several processes.

Importance of Wastewater Treatment

Wastewater treatment is essential for several reasons:

  • It helps to protect public health by removing harmful contaminants from wastewater.
  • It helps to protect the environment by preventing the contamination of water bodies.
  • It helps to conserve water resources by recycling treated wastewater for various purposes.

Wastewater Treatment Process

The wastewater treatment process involves several stages:

  1. Preliminary Treatment: This stage involves screening and grit removal to remove large objects and debris from the wastewater.
  2. Primary Treatment: This stage involves sedimentation and flotation to remove suspended solids and organic matter from the wastewater.
  3. Secondary Treatment: This stage involves biological processes such as activated sludge, trickling filters, and rotating biological contactors to remove dissolved organic matter and nutrients from the wastewater.
  4. Tertiary Treatment: This stage involves advanced treatment processes such as filtration, disinfection, and reverse osmosis to remove remaining contaminants from the wastewater.
