Another important application of chemical dosing is coagulation and flocculation. In this process, coagulants like aluminum sulfate or ferric chloride are added to the water. These chemicals bind with suspended particles, forming larger aggregates or flocs that can be easily removed during sedimentation or filtration. This step is particularly important in treating water from surface sources, which often contains high levels of turbidity due to silt, clay, and organic matter.

Beyond chlorination, other disinfectants such as ozone and ultraviolet (UV) light have also gained popularity in chemical water treatment. Ozone, a more potent oxidizing agent than chlorine, can break down organic pollutants and disinfection byproducts. Its short lifespan in water means it must be generated on-site, but it offers an effective alternative, especially in water with high organic load. Meanwhile, UV treatment involves exposing water to UV light, which disrupts the DNA of pathogens, rendering them inactive. This method does not introduce any chemicals into the water, making it a preferred option for many purification processes.
