TREATMENT OF PETROLEUM REFINERY WASTEWATER IN AN INNOVATIVE SEQUENCING BATCH REACTOR
The difficulty with sludge settleability is considered one of the main drawbacks of sequencing batch reactors. The aim of this study therefore is to improve sludge settleability by introducing a novel, two-stage settling sequencing batch reactor (TSSBR) separated by an anoxic stage. The performance …

Should Oil-Producing Countries Go Downstream?
The expansion of the refinery capacity in oil-producing countries is a rising trend. The fact that the majority of oil producers have already begun to vertically integrate into the downstream oil refining segment calls for a detailed examination of the implication of such investments. Oil-producing …
