✦ Synopsis

The problem and disposal of wastewater has been tremendously increased since the great expansion in industrialization in Egypt. The discharge of there large quantities of wastewater into the river Nile without treatment and through control of its specifications would affect the general uses of the river water for both drinking and irrigation purposes, besides its damaging effect on aquatic life.

Wastewater from electroplating industries is characterised by its high content of heavy metals such as: Cr, Zn, Cu, Fe and Mn. Heavy industries neer the city of Helwan to the south of Cairo also must keep control of its wastewater-effluents-specifications before discharging into the Nile.

In this work,threesamples have been collected: one from an electroplating factory; the second from a small branch of the river Nile considered as a sum of more than one industry & the third from electrical power station. Atomic absorption techniques have been adopted to quantify the aforementioned heavy metals concentrations in these samples. Comparison with the allowable standards has been carried out. General suggestions about suitable treatment methods are also given when necessary.
