The increasingly growth of population led to an increase in the number of
different industrial plants and to arise in their productive capacity which led
to the formation of large quantities of waste products in their gas, liquid and
solid forms.
These waste products led , in turn , to pollute the air , water and soil. This pollution
endangers the whole environment.
In this paper we studied one of the aspects of waterpollution used in chemical
fertilizers factories and the ways of treatment stations designing and the great
role played by these stations in diminishing the great damage caused to rivers ,
lakes , seas and water –store. This has positively a good effect on environment
and economy in general.
It is necessary to operate the used-water treatment stations and recycling this
water after purifying and refining it within the closed-circuit system effectively
and by using modern computerized techniques concerning design , operation and
investment.
This study is of four chapters and a list of references.
The first chapter includes a short glimpse about the treatment stations and their
main lines concerning design and distribution.
The second chapter is about the sections of the phosphate fertilizers factories and
about the acidic water resulting from these sections.
The third chapter gives a glimpse about the treatment of polluted water in the
phosphate fertilizers factory.
The fourth chapter includes the practical section with some designs and results.
Finally , a list of the arabic and foreign references.
