The steps included the water treatment process are
Sedimentation
Filtration
Disinfection
The first stage includes treatments like conventional sedimentation, filtration and chlorination .
Disinfection and dechlorination is the final step of the wastewater treatment process.
Fluorination is a process whereby plastic containers are exposed to fluorine atoms under controlled conditions.This improves the high-binding energy and resistance of the plastic container and therefore, lower permeation.
Excess fluorine in drinking water can accumulate in teeth and bones, causing fluorosis.
