Abstract
Wastewater treatment is one of the biggest challenges which faces
the majority of countries in order to obtain clear water which dose not
cause considerable threat to healthy or the environment, especially
country like Egypt that suffer from large population and lake in fresh
water resources. There are several methods for wastewater treatment but
each of them faces considerable problems. Some problems concern with
the huge consumption of energy and other problems concern with the
efficiency of the treatment process. This study aims to investigate the
possibility of using nanomaterials to develop wastewater treatment
process with high efficiency and lower energy consumption. Magnetite
nanoparticles is selected in this study for two main reasons the first is
they do not have toxic effect and the other reason is to employ the
magnetic properties of magnetite for easier separation from the water by
applying external magnetic field. Magnetite nanoparticles was
functionalized with some materials that acted as shell to protect magnetite
from oxidation and contact with polluted water with wide rang
substances. Chemical Oxygen Demand (COD) is selected as a parameter
of pollutants in wastewater because the majority of contaminates in
wastewater are organic matters
