Abstract By-products and wastes generated by the oil gas industry must be properly managed treated. Oil-drilling cuttings (ODCs) are major during process of oil/gas exploration extraction. ODCsispre-treated in a sonicator mixing it with synthetic seawater pre-specified composition at varying volume ratios, presence anionic surfactant sodium dodecyl sulphate (SDS) various concentrations (0%, 0.2...
Oil companies have released billions of gallons of untreated wastes and oil directly into the environment of the Ecuadorian Amazon. This cross-sectional study investigated the environmental conditions and reproductive health of women living in rural communities surrounded by oil fields in the Amazon basin and in unexposed communities. Water from local streams was analyzed for total petroleum hy...
Bioremediation techniques are being developed as substitutes for physical–chemical methodologies that expensive and not sustainable. For example, using the agricultural waste spent mushroom substrate (SMS) which contains valuable microbiota soil bioremediation. In this work, SMSs of four cultivated fungal species, Pleurotus eryngii, Lentinula edodes, ostreatus, Agaricus bisporus were evaluated ...
Petroleum hydrocarbon status of the Buffalo River Estuary in East London, South Africa, was evaluated from January to May, 2016. Surface water and sediment samples were collected from five points in the estuary and extracted using standard methods. The extracts were subsequently analyzed by gas chromatography-flame ionization detection. Results showed that total petroleum hydrocarbon (TPH) vari...
BACKGROUND A novel implementation of a hybrid membrane bioreactor (HMBR) has been studied in this paper. It is utilized as combination of rotating biological contractor (RBC) and an external membrane, as a new biological system for oily wastewater treatment. METHODS Chemical oxygen demand (COD) and total petroleum hydrocarbon (TPH) as factors of Biodegradability has been evaluated. They are b...
Zero-valent iron nano-particle (nZVI) was modified with Spondias mombin (Sm) leaves extract (Sm-nZVI) for the removal of total petroleum hydrocarbons (TPH), hydrocarbon content (THC), and polycyclic aromatic (PAHs) from contaminated soil. Advanced analytical tools such as Fourier Transform Infra-Red (FT-IR) Spectrophotometer, Scanning Electron Microscope(SEM) X-ray diffractometer (XRD) were use...
today oil removal from contaminated soil by new methods such as bioremediation is necessary. in this paper, the effect of chemical fertilizers and aeration on bioremediation of oil-contaminated soil has been investigated. also the control group, (bioremediation of petroleum hydrocarbons in contaminated soil without treatment by chemical fertilizers and aeration treatment was examined. the cond...
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 ...
This greenhouse experiment aimed to investigate the effects of poultry manure (PM) on the growth of oat plant (Avena sativa) and removal of total petroleum hydrocarbons (TPHs) from soil. The treatments consisted of three TPH levels (4%, 6%, and 8% w/w) and two PM levels (zero and 1%) at three replications. According to the findings, shoot height, number of leaves, and the fresh and dry...
