Abstract

A field study was conducted at the 55 MGD Dammam (Saudi Arabia) wastewater treatment plant employing the carrousel system, to evaluate its overall performance with particular emphasis on nitrogen removal. The results of the study showed that the plant achieved greater than 93% BOD removal, 99% ammonia reduction, and 93% TKN removal. The plant readily met the secondary effluent BOD₅ requirement with an average BOD₅ concentration of 8.2 mg l⁻¹, but barely satisfied the SS standard with effluent SS averaging around 29 mg l⁻¹. While the average total effluent nitrogen was 4.4 mg l⁻¹, nitrification-denitrification accounted for about 45% of the total nitrogen removal. The system kinetics for BOD₅ and ammonia removal conformed to the plug-flow first-order kinetic model. Kinetic parameters estimated in this study were well within literature values.
