Abstract
The River Nile and its two branches (Damietta and Rosetta) are
considered to be the principal artery for the Egyptian life. The present
work concerning with the study of the environmental status of the River
Nile at the area extended from the Egyptian Iron and Steel Company
(ETSC) in El-Tebbin city in 1-leiwan govemorate at the south to the
Egyptian Sugar & Integrated Industries Company (ESIIC) at north in El
Hawamdya city in Giza governorate. Along, this area (approximately 25
1cm), there are different sources of pollution directly poured into the River
Nile without any treatment. These sources are situated along the studied
area which can be divided into several types; Industrial inorganic wastes
as in case of EISC drains and the industrial organic effluents was present
in EIISC drains which causing thermal and organic pollution. These
would certainly lead to change in the water quality of River Nile at the
points discharge. The aim of this work is to evaluate the environmental
status of the River Nile at the sites exposed to the two factories EISC and
EIISC drains, through, physical and chemical analysis of the water
samples were collected from these sites. As well as, some chemical
treatment were calTied out using modified date pits, rice husk and
advanced oxidation techniques to treat the effluents of these drains during
the period started from January 2004 to December 2004.
The present work includes three chapters, in which, a brief
description of these chapters are given below:-
The first chapter includes introduction: the description of the
River Nile and industrial pollution risks. Also, historical background on
the two factories (EISC and EIISC) studied. In addition to, literature
survey of the previous work concerning with physical and chemical
characteristics of the River Nile water and other fresh water ecosystem.
