About service

Sewage Treatment Plant

A Sewage Treatment Plant (STP) is a facility designed to remove contaminants from wastewater, primarily from household sewage. It uses physical, chemical, and biological processes to treat sewage and produce environmentally safe treated effluent and solid waste, or sludge, suitable for disposal or reuse.

  • Environmental Protection: Reduces water pollution and safeguards aquatic ecosystems.
  • Public Health: Minimizes risks of waterborne diseases and improves sanitation.
  • Resource Recovery: Treats sludge for safe disposal or use as fertilizer and recycles treated water for various uses.

Primary Treatment

Involves the physical removal of large particles and sediments through screening and sedimentation.

Secondary Treatment

Biological processes such as activated sludge or biofilters degrade organic matter and remove dissolved and suspended biological waste.

Tertiary Treatment

Advanced treatment to remove nutrients, pathogens, and other pollutants to ensure the water is safe for discharge or reuse.

Sludge Management

The by-product sludge is further treated, dewatered, and may be used as fertilizer or disposed of safely.
