Abstract: Water is the major waste generated in industries. During the exploration and production of oil
produced water is generated with oil which is much more in quantity than oil. As the age of well
increases the production of oil decreases and water increases. As oil is considered gold, wells
are being dug deeper and deeper hence increasing the quantity of waste water. But in future
water will be gold and this waste water will be recycled and reuse.
Effluent treatment plants are designed to treat this waste water for disposal. The design of water
treatment plant is continuously advancing technology. The design scheme consists of a series of
physic-chemical treatments. Only one type of treatment should not be used instead a series of
treatments should be used to achieve the desired quality of water. The design scheme suggested
in this study consists of primary treatment, secondary treatment, tertiary treatment and advanced
treatment.
Instead of disposing the produced water, if treated properly it can be recycled and reused even
for drinking purposes. Countries in arid regions have technologies that treat the produced water
and make it fir for drinking purposes. Hence reducing stress on fresh water resources as well as
reducing pollution on water resources. Therefore the goal of modern design should be to
optimize the complete water treatment system to take advantage of modern technology.
