Modeling and Optimization the Conductivity of Wastewater Discharged into the Bouregreg River (Rabat, Morocco) in Function of Ions: Chlorides, Sulphates, Nitrates and Bicarbonates

Abstract

Discharges of domestic and industrial wastewater in the two banks of the Bouregreg River without any treatment, usually has a large number of health and environmental risks, among these water pollution by dangerous chemicals. The Objective of this study is to follow the variation of the conductivity of wastewater discharged into the Bouregreg river depending on the anions concentration of chlorides (Cl^-), sulfates (SO₄^2-), bicarbonates (HCO₃^-) and nitrates (NO₃^-) to determine the ions that have an effect on this physicochemical parameter for modeling and optimization this parameter according anions analyzed in wastewater discharged into the Bouregreg river with help of the experimental designs method and isoresponses curves.

Keywords: Conductivity; waste water; anions; modeling; optimization.
