Distribution and elimination of petroleum products can be predicted in aerobic wastewater treatment plants (WWTPs) using models such as multimedia fate model SimpleTreat. An advantage the SimpleTreat is that it only requires a few basic properties chemical to calculate partitioning, biodegradation ultimately emissions air, surface water produced sludge. The structure reflects WWTP scheme. Howev...

Contamination of the water bodies occurs from different sources including oil refineries. Oil refinery effluent contains different chemicals at different concentrations including ammonia, sulphides, phenol, hydrocarbons and heavy metals. Monitoring the impact of pollutants on aquatic life forms is challenging due to the differential sensitivities of organisms to a given pollutant, and the inabi...

The environment is considered as man’s important asset that must be protected for his life support. Regrettably the situation is different where oil refinery and petrochemical plants operate. Environmental pollution in the form of emissions and effluent discharge in these area poses serious threat to the ecosystem particularly soil, often with undesirable effects. The study collected soil sampl...

Conventional biological treatment process is not very efficient for the treatment of petroleum refinery wastewater (PRW) that contains high-concentration of organic contaminants. Prior to biological treatment, an additional pretreatment process for PRW is required for the effluent to meet the discharge standards. While re-circulated bio-filter (RBF) has been applied as a pretreatment process in...

Electro-oxidation, also called electrochemical advanced oxidation, uses electricity to generate hydroxyl radicals to perform oxidation in wastewater treatment. A new commercially available electro-oxidation process—Zimpro® Electro-oxidation (ZEO)—is especially effective for treating the highly problematic spent caustic streams produced by sweetening operations in petroleum refineries and ethyle...

The fisheries sector is one of the most ancient and important sectors in world plays a significant role providing nutrition socio-economic development country. fish processing industry produces huge quantities wastewater, encompassing amounts contaminants form soluble, colloidal, particulate matters. disposal shellfish waste serious issue, effluents discharged from seafood-processing plants con...

in this survey, with the main objective of studying final effluent treat ability of pars paper industries, the quantitative and qualitative characteristics of the effluent were firstly determined, which showed a min. and max. rate of 1350 and 1800 m3/hr, with 1400 mg/l and 839.5 mg/l respectively for cod and tss, as the main contaminants. also cod and tss population equivalents were calculated ...

The activities involved in the production and exploration of crude oil has constantly polluted environment. This study investigated ability an indigenous fungus to utilize petroleum hydrocarbon. Response Surface Methodology was used optimize effects pH, microbial concentration (spores/ml), contact time (days) on removal efficiency refinery effluent. Monocillium sp. isolated for treatment efflue...
