English Abstract

Tertiary treatment was given to the secondary wastewater effluent of the North Aramco Wastewater Treatment Plant, Dhahran, in order to utilize it for unrestricted reuse and landscape irrigation. The process employed for this study consisted of coagulation, flocculation, sedimentation, granular media filtration and chlorination. A bench scale study was conducted to optimize coagulant dosages and filtration rate to produce a satisfactory filtered effluent for chlorination. Based upon the experimental data, a coagulant dosage and filtration rate was suggested for the tertiary treatment of two kinds of wastewater effluent (chlorinated and unchlorinated). A mathematical relationship was developed based upon the batch chlorination data to determine the chlorine residual and contact time to achieve an effluent coliform concentration of less than 2.2 MPN/100 m1 that is safe for unrestricted reuse as described by Title 22 of California Administrative Code.
