Water Treatment Process
Water Treatment Process is the removal of contaminants from untreated water to
produce water that is pure enough for its intended use, most commonly human
consumption.
Substances that are removed during the Water Treatment process
include suspended solids, bacteria, algae, viruses, fungi, minerals such as iron,
manganese and sulphur, and man-made chemical pollutants including fertilisers.
In
general the methods used include physical processes such as filtration and
sedimentation, biological processes such as slow sand filters or activated sludge,
chemical processes such as flocculation and chlorination and the use of
electromagnetic radiation such as ultraviolet light.
Water is purified often using two methods: reverse osmosis, sometimes called ultra
filtration, and distillation.
In reverse osmosis, water is ran through a semi-membrane
under high pressure.
Pores in this membrane are small enough to let water
molecules run through it while stopping larger mo
