phenol is an environmental pollutant present in industrial wastewaters such as refineries, coal processing and petrochemicals products. in this study three phenol degrading bacteria from arak petrochemical complex effluent were isolated which consume phenol. molecular analysis was used to identify bacteria and isolated bacteria were identified as rhodococcus pyridinivorans (ns1), advenella faec...

One of the industrial areas in the south of Iran is Bandar Imam Petrochemical Economic Zone which has a lot of petrochemical complex, Farabi Petrochemical complex is one of those places. Coagulation/flocculation could be a typical methodology in water and wastewater treatment that a number of chemicals are added to assist the coagulation/flocculation and causes to the sedimentation. In this pap...

results the results showed that the pcp degradation increased with an increase in zvi dosage from 0.056 to 1.4 g/l, an increase in persulfate concentration from 2.5 to 15.0 mm/l, and an increase in zvi to ps molar ratio from 0.1 to 2.5. the optimal initial ph for pcp removal was 5.0 and the maximum removal efficiency of 70% was achieved within 120 minutes. moreover, the zvi catalyst was reused ...

Phenolic derivatives are used as raw materials in textiles, pulp and paper, petrochemical, pharmaceutical, oil-refineries and leather industries. These heterocyclic aromatic chemicals are among the most frequently found pollutants in industrial effluents. Since these compounds are toxic either through ingestion, inhalation or contact even at low concentrations, biodegradation of the effluent is...

Establishment of great industrial centers and ports along the Khur-Musa Estuary in Mahshahr Port (Khuzestan, Iran) have been discharged a high volume of industrial and non-industrial pollutants to this estuary. The most important pollutants in Khur-Musa include industrial wastes and effluents including ammonia and urea units. This research aimed to survey the qualitative parameters of effluent ...

Investigations were carried out to determine the composition of fungal flora in the studied sites. Samples of the raw effluent were collected along the flow channel and the retention pond. Water samples were also collected at the discharge point and up and down stream of the river from the discharge point. The samples were spinned at a speed of 250rpm for 10minutes and spread inoculated the dep...

Petrochemical industry generates highly toxic effluents with a large variety of chemicals, being most of them recalcitrant and toxic such as: organic chlorinated compounds (mainly 1,2 dichloroethane) and volatile and semivolatile organic compounds. The most common wastewater treatment systems used in Mexico to treat this kind of effluents are activated sludge and aerated lagoons. Treatibility s...

Petrochemical industries can potentially impact the environment due to their activities and products. This case study has considered adverse effects of petrochemical industries that are located inside the PETZONE with respect to the presence of polycyclic aromatic hydrocarbons and total petroleum hydrocarbon in wastewater effluents. The average concentrations of ∑PAHs group I and II were lower ...
