Water and wastewater treatment 2014 is a rapidly increasing industry that provides thousands of job
opportunities for vendors and contractors alike. Vendors can bid on various kinds of water and
wastewater treatment projects posted by Water utility companies. But first, let us understand the water
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.

treatment. Here, household sewage
and industrial effluents are treated to
remove
physical,
biological
and
chemical contaminants. Once the
sewage is treated, it can be safely
released into the environment. The
treated fluid wastes and sludge is
put to good use as farm fertilizer.
Just as chemicals are used to purify
water,

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.
