GONZALEZ, Youseli; RINCON, Nancy; LOPEZ, Franklin  and  DIAZ, Altamira. Organic matter removal from the petroleum effluents by a sequencing batch reactor (SBR). Rev. Téc. Ing. Univ. Zulia [online]. 2007, vol.30, n.Especial, pp.82-89. ISSN 0254-0770.

Tía Juana Liviano (TJL), Urdaneta Pesado (UP) oil wastewaters from the Tank-Yard Ulé in the west cost of Lago de Maracaibo of Petroleum Venezuelan industry, were treated in aerobics conditions by Sequencing Batch Reactors (SBR) to determinate the organic matter (hydrocarbons and phenols) removal efficiency. The evaluated parameters in this study were pH, Alkalinity, TSS, DO, COD, TOC, Total Nitrogen, THC and total Phenols. The COD, totals phenols and totals hydrocarbons removal observed in Light Petroleum Extraction effluent (EEPL) and the Heavy Petroleum Extraction effluent (EEPP) were maximum 96% and 72%, respectively.

Keywords : Sequencing batch reactor (SBR); oil production wastewater; light oil and heavy oil.
