Sulfur compounds are removed from petroleum by the addition of sodium hydroxide at a very high concentration. As a result, a residue called spent soda or spent caustic is generated, being extremely aggressive to the environment. In this work, the chemical properties of this residue are described in detail. The sodium hydroxide remains that have not reacted, sulfur compounds, and organic matter ...

Oily wastewater, from restaurant was treated with UV/TiO 2 under the following conditions of 10 min of radiation, 150 mg/L of TiO 2, and pH of 7.0. The study revealed the removal efficiency of COD, BOD, and oil of 63%, 43%, and 70%, respectively, it was reported by Kang et al. [45] Furthermore, Agustina et al. [1] reported the treatment of winery ,wastewater, with TiO 2 /H 2 O 2; about 84% COD ...

The WD-PAC and ACTF-PAC materials reflect a good gasoline and condensate oil adsorption capacity (q e , mg.g−1) from ,wastewater, with high kinetics rates within 2–4 h contact time. Kinetic adsorption was found to behave as a pseudo-second kinetic model and controlled by a diffusion mechanism with an exothermic nature.

Hazardous waste is any solid waste that either exhibits any of the ,characteristics, of hazardous waste or is a listed EPA waste. In addition, EPA Hazardous Waste Codes are also classified as acute and non-acute. P-listed codes and certain dioxin codes (F020-F023 and F026-F028) are considered to be acute, whereas the remaining codes are non-acute.

Among those existing methods for ,oily wastewater, treatment, degradation of oil contaminates by microorganisms has been highly favored owing to its advantages of low cost and no secondary pollution. (5,6) In general, a single bacterial strain can degrade only a few specific hydrocarbons or to a certain stage due to the complexity of petroleum composition and the difficulty in degrading.

For ,oily wastewater, separation, the most important issue to be addressed is to decrease the attachment of oil droplets on the membrane surface. This can be mitigated by surface modification method in which hydrophilic or oleophobic materials are immobilized onto the membrane surface either by chemical reaction or physical adsorption to provide a stable fouling resistance layer.
