Coagulation and Flocculation
The water treatment narrative often begins with the removal of suspended solids. The process is initiated when raw water is treated with chemicals like aluminum sulfate or ferric chloride. These coagulants neutralize the electrical charges of fine particles, causing them to clump together. This clumping, termed flocculation, creates larger, heavier particles called ‘floc’ that can then be more easily removed during subsequent settling or filtration stages. The efficiency of coagulation-flocculation directly impacts the clarity of the final product. If this stage is compromised, residual turbidity might persist, influencing public perception of the water’s purity.
-
Sedimentation and Filtration
Once flocculated, the water enters sedimentation basins where gravity takes its course. The heavier floc settles to the bottom, leaving clearer water to proceed. This clarified water is then passed through filtration systems composed of sand, gravel, or activated carbon. These filters act as physical barriers, removing remaining suspended particles, pathogens, and even some dissolved organic matter. Filter integrity is paramount. A breach in the filter medium can allow contaminants to bypass the treatment process, impacting the water’s safety and clarity.
