An investigation into factors affecting the efficacy of oil removal from wildlife using magnetic particle technology
… factors affecting the efficacy of the magnetic removal of oil contamination from a variety of matrices, including feathers and plumage, have been investigated. Employing electron microscopy and an established gravimetric methodology, detailed investigations into the effect of particle size, …

Bioremediation of modelled petroleum-contaminated soils of the Niger Delta and the impact of zeolite augmentation
The bioremediation of modelled petroleum oil-contaminated soils of the Niger Delta by a mixed culture of three hydrocarbon-degrading bacteria, Acinetobacter sp, Rhodococcus sp and Pseudomonas sp, was investigated. These bacterial strains were selected based on criteria that they were able to …

Synthesis of Acid Leached Diatomaceous Earth/ Amine-Functionalized Activated Carbon Composite and its Potential Application in Oily Wastewater Treatment
Due to the expanding worldwide oil exploration, a significant amount of oily wastewater is being produced. Oily wastewater lowers the diversity of aquatic life and plants by changing the structure of aquatic communities and food chains, among other ecological disturbances. Therefore, the overall …

Fundamental study of hydrophobic microporous membrane contactors for the recovery of insoluble oil from oil-water mixtures
Insoluble oil and water mixtures occur in many industries such as food, metallurgical, or biofuel production. In particular, as we strive to meet global energy demands, the associated risks and waste management of the oil and gas industry must be addressed. Technologies capable of separating oil …

Enhancement of fluidization and filtration using nanoparticle agglomerates and aerogels
… granules-Nanogel-has been studied for the removal of oil from wastewater. The granules are several hundred microns or larger in size, but they have a nano-porous structure that provides large surface area and low density. The hydrodynamic characteristics of the granules during inverse …

Nanocompósito de poliamida/óxido de grafeno reduzido: um eficiente nanomaterial aplicado no tratamento de água produzida (ap) e separação de óleo/água do mar
Contamination derived from water produced from oil reservoirs and oil spills at sea are environmental problems of great relevance. Therefore, the search for effective, sustainable, easy-to-apply and low-cost methods for oil/water separation has been the subject of many studies in the last two …

Produced Water Treament Using DAF With a Mixture of Ionic Liquids and Organoclay as Pre-treatment Chemicals
… the process. The average production of water to oil in oil producing well is currently estimated at a ratio of 3:1 in favour of water, this number is estimated to rise to as high 12:1 in the next decade. Hence the onus is on researchers to meet up with the demands that come from the volume of …

Inverse solid-liquid fluidization of aerogel granules and its application in removing oil from water
… aerogel granules and using this system to remove oil from an oil-water mixture. The solid particles employed for this study are low density (100 kg/m^3) surface treated hydrophobic aerogel (Nanogel ) granules of size in the range of 0.5 to 2.3 mm. These particles are highly porous characterized by …
