Infrastructure systems that purify and process water for human consumption and environmental protection through multiple stages of physical, chemical, and biological treatment.

Water Treatment Facilities

Water treatment facilities are complex infrastructural systems designed to transform raw water into safe drinking water and process wastewater before releasing it back into the environment. These facilities represent a crucial intersection of public health, environmental protection, and urban infrastructure.

Core Functions

Drinking Water Treatment

Preliminary Screening: Removal of large debris using screens and filters
Coagulation and Flocculation: Addition of chemicals to bind small particles
Sedimentation: Settling of particle clusters
Filtration: Removal of remaining particles through sand filtration and other media
Disinfection: Elimination of harmful microorganisms using chlorination or UV treatment

Wastewater Processing

Primary Treatment
- Physical separation of solids
- Grit removal
- Initial sedimentation
Secondary Treatment
- Biological treatment using microorganisms
- Aeration and mixing
- Secondary clarification
Tertiary Treatment
- Advanced filtering
- Nutrient removal
- Final disinfection
