Water Purification

Water purification represents the diverse set of methods and technologies used to transform water into clean, safe forms suitable for human consumption and other uses. This fundamental process sits at the intersection of public health, environmental science, and engineering.

Core Methods

Physical Purification

• Filtration through various media (sand, ceramic, membrane)
• Sedimentation for particle settling
• Distillation for separation of water from contaminants
• Ultraviolet Light for disinfection

Chemical Treatment

• Chlorination for pathogen elimination
• Flocculation to remove suspended particles
• pH Balance adjustment
• Activated Carbon for organic compound removal

Biological Processing

• Biofiltration using beneficial microorganisms
• Aerobic Treatment for organic matter breakdown
• Wetland Systems for ecological purification

Applications
