The corrosion rate of steel plate using single-factor, multifactor, and complex water systems was investigated via refinery wastewater effluents used as circulating cooling water. The results show that the primary corrosion factors of steel depend on the characteristics of the ions, the formation of the oxidized coating, the diffusion of dissolved oxygen, and other complex factors, although ion...

Distilleries produce vast amounts of contaminated effluents which if disposed to the water bodies will pose environmental problems hence need to treat this effluent. A membrane bioreactor with Pseudomonas fluorescens as a decolorizing micro-organism was employed for treatment of distillery effluent over 10 days. The effluent pH changed from being acidic (4.2-5.0) to neutral (7.3-8.0). The efflu...

Ion exclusion is a chromatographic process which separates components from an impure feedstock on the basis of molecular size and charge. A pilot plant ion exclusion separator was constructed to determine the technical and economic feasibility of recovering sugar from refinery jet 4 (the feedstock identified as most promising in terms of ease of treatment). Extensive tests on jet 4 from the Mal...

This study was undertaken to evaluate a novel aerobic wastewater treatment model for the remediation of refinery effluents and to assess the removal efficiency of Bulkholderia cepacia strain AJI and Corynebacterium kutscheri strain AJ2 to clean oil waste from petrochemical company. Wastewater quality parameters including pH, BOD5, COD, TDS, OIL & GREASE, PHENOL concentration, TPH and THC were m...

Reasons for Blending Crude Oils at a Refinery Oil refineries, and especially their on-process units that process the primary crude feed stocks, are not uniform in either design or operation. The refinery process units and the combination of units built and in service at a given refinery location are part of a plan to accommodate a certain slate of crudes based on their properties. These decisio...

Phenol and its derivatives are hazardous, teratogenic mutagenic, have gained significant attention in recent years due to their high toxicity even at low concentrations. Phenolic compounds appear petroleum refinery wastewater from several sources, such as the neutralized spent caustic waste streams, tank water drain, desalter effluent production unit. Therefore, effective treatments of wastewat...

Effectiveness of ozonation before and after biological treatment for removal of recalcitrant organic matter in bleached kraft pulp effluents was compared. Two industrial ECF bleached eucalypt kraft pulp effluents (E1 and E2) were pretreated with 100 mg O3/L. Raw and pretreated effluents were treated biologically in bench-scale sequencing batch reactors, under constant conditions. Following biol...

UNLABELLED Common effluent treatment plant (CETP) for tannery effluent, is the combination of physical, chemical and biological treatment to facilitate the degradation of industrial waste water. Obviously, the biomass which survives in this extreme environment may have the ability to utilize the effluent as the sole carbon source for its survival. The ultimate aim of the present investigation i...

Dyes and other chemicals laden wastewater is a main environmental concern for increasing the textile industries in many parts of world. Textile consume different kinds manmade dyes or release huge extents highly polluted water into environment. This excessive dye has great impacts on photosynthetic activity aquatic plants animals, example, fish. It may also affect human health due to presence c...
