Environmental Management of Siah-Rud River and Economic Analysis on Sewage Purification

Considering the water scarcity in Iran and the importance of
environmental protection, it is approperiate to investigate the
\ environmental management of Siah-Rud river. It is a small river
being utilized as discharge channel by factories located in the
vicinity of the river. The physico-chemical characteristics of river
water at 10 different sampling locations 'along with coefficient of
aeration (K1, Kd) , and self purification of the river were determined.
Using a linear computer programme , an optimization-model for the
minimum treatment efficiency at each pollutant source, along with
dissolved oxygen and BOD, in the course of river was developed
