Sewage Treatment

Sewage treatment is a complex process that removes contaminants from wastewater to protect public health and the environment. Untreated sewage contains harmful bacteria, viruses, and other pollutants that can cause disease and contaminate water sources. This multi-stage process is designed to remove these contaminants and produce treated wastewater that is safe for discharge into the environment.

The typical sewage treatment process involves several stages:

  • Preliminary Treatment: Wastewater is screened to remove large objects like debris, rags, and plastics.
  • Primary Treatment: Sedimentation removes settleable solids and organic matter through settling in clarifiers.
  • Secondary Treatment: Microorganisms consume organic matter in wastewater through a biological process, further reducing contaminants.
  • Disinfection: Treated wastewater is disinfected with chemicals like chlorine to kill remaining bacteria and viruses.

How Clean is Water After Sewage Treatment?

Treated wastewater meets strict standards set by environmental regulations. It is typically safe for discharge into waterways or for use in irrigation. However, some contaminants may remain even after treatment, making it unsuitable for drinking or other sensitive uses.

The effectiveness of sewage treatment varies depending on the type of treatment plant and the influent wastewater quality. Advanced treatment technologies, such as membrane filtration, can remove additional contaminants, producing water suitable for reuse or replenishing groundwater aquifers.
