The current study evaluates the performance of a pilot scale fed batch reactor (FBR), fo llowed by coagulation and sand filtration, for the treatment of an oil refinery wastewater. The total reductions in COD, BOD, oil contents and phenol were 95.11%, 94.30%, 99.47% and 100%, respectively, with FBR followed by coagulation and sand filtration. This FBR-coagulation-sand filtration treatment syste...

A simple and efficient protocol is utilized for the transformation studies of a thiophene analog E-resveratrol by photocatalytic oxygenation using an anionic cationic free-base porphyrin, as well their manganese(III) complexes. The starting substrate was chosen representative heterostilbenes with proven good antioxidant activity. experiments were carried out in two photoreactor types (batch mic...

due to the population growth and human activities in the agricultural and industrial fields, healthy and sanitary water has become scarce. due to its high contamination load, environmental harms and water discharge standards, starch producing industry is regarded as one of the industries polluting water sources which its treatment and recovery remains important. in the present study, after fabr...

Anaerobic dechlorination of pentachlorophenol (PCP) was studied in two upflow anaerobic sludge blanket reactors. One reactor received glucose (0.9 g liter-1) as an additional carbon source; the other one served as a control. The concentration of PCP in the medium was 4.5 and 3.0 mg liter-1 in the experimental and control reactors, respectively. The reactors were inoculated with granular sludge ...
