response of cyprinus carpio to phenol and furfural shock loads in pact system
treatment efficiency, design factors and kinetic coefficients were studied using two pilots of activated sludge (as) and powdered activated carbon technology (pact), for treating tehran oil refinery effluent, in a duration of more than 12 months in order to evaluate the performance of each system against growth inhibitor shock loads, different concentrations of phenol and furfural (10-300 mg/l)...
متن کاملExperimental Comparison of Two Modifications of Activated Sludge for Treatment of Furfural-Containing Wastewater
A case study is presented in which two modifications of activated sludge treatment of complex chemical wastewater are experimentally compared: a combination of common activated sludge with powdered activated carbon treatment (PACT), and bioaugmentation of activated sludge treatment (BAST). Industrial wastewater of Pars Oil Refinery that was passed through an oil recovery stage was used to inve...
متن کاملPerformance Evaluation of Combined Process of Powdered Activated Carbon-Activated Sludge (PACT) in Textile Dye Removal
Introduction: The Powdered Activated Carbon Treatment (PACT) has been proposed as an alternative in wastewater treatment and wastewater biomass protection against toxic substances. This study aims to evaluate PACT performance in treating dyes, acid orange, and remazol brilliant reactive blue. Materials and Methods: This empirical- applied research was carried out in pilot scale in which differ...
متن کاملModeling and Experimental Prediction of Wastewater Treatment Efficiency in Oil Refineries Using Activated Sludge Process
In this study, activated sludge process for wastewater treatment in a refinery was investigated. For such purpose, a laboratory scale rig was built. The effect of several parameters such as temperature, residence time, effect of Leca (filling-in percentage of the reactor by Leca) and UV radiation on COD removal efficiency were experimentally examined. Maximum COD removal efficiency was obtained...
