and wastewater treatment as a process that is extremely essential for the health of the civic society as well
as the environment as a whole.
Water treatment is the process of making the ground water acceptable for human consumption by
removing or reducing the contaminants present. There are two ways in which water is treated to make it
fit for drinking. Settling and filtration is the physical process that separates unwanted solids present in raw
water. The other is the chemical process where disinfection and coagulation is carried out to treat water to
make it fit for drinking. Water is also treated by electromagnetic radiation or ultraviolet rays.
Chemical water purification involves
the use of chemicals like chlorine to
purify the water. Chlorination of
water ensures the removal of harmful
bacteria, algae and fungi that may be
present in the water. Other chlorine
based compounds such as chlorine
dioxide and chloramine are also used
to disinfect drinking water.

environment. The treated fluid
wastes and sludge is put to
good use as farm fertilizer.
Just as chemicals are used to
purify water, they are also used in wastewater treatment process to make it suitable for use.
Toxic metals from wastewater are removed by chemical precipitation, a process where a chemical
is added to wastewater to convert the dissolved metals into solids so that they can be filtered out.
Chemical coagulation helps the fine solids in wastewater fluids to bind together and settle down.
These particles are then removed by sedimentation.
Chemical oxidation is used to modify the polluting bodies in the wastewater so that they become
less harmful to the environment.
