––The oily mud waste is one of the main wastes in oil field production process, which also stands as a critical negative factor that impedes the improvement of oilfield environment. The oily mud, which is rich in oil and black viscous compound in appearance, is the solid waste that comes along with the oilfield production. The oily mud mixture has huge amounts in magnitude, and it contains a ce...

Oily wastewater generated from various industrial processes and oil spillages is a massive threat to the environment human health. Hence, it essential develop novel material for practical oil/water separation recovery. By incorporating WO3 (tungsten oxide)/ N-CQDs (amino-functionalized carbon quantum dots) into matrix of polymer, alteration wettability behavior electrospun PLA fiber reported in...

This work aims at selecting a suitable strategy to accelerate the start-up of the anaerobic treatment of olive mill wastewater (OMW) and to enhance the biogas production. Two anaerobic sludges were tested in toxicity and biodegradability batch experiments: biomass acclimated to oleate (BAO) and biomass non-acclimated (BNA). The results showed that the resistance to OMW toxicity was higher for t...

Abstract With the development of industry, more and oily wastewater is discharged into water, which brings great harm to ecological environment human health. Membrane separation technology a very promising for treatment. In this experiment, 1:1 mixed solution formic acid dichloromethane (FA/DCM) was used as solvent prepare PA66 microfiltration membrane by evaporation method, nano-SiO 2 modify w...

to study the feasibility of anaerobic filter in raw sewage and slaughter house wastewater treatment, slaughter house wastewater treatment, a batch flow pilot plant was designed. in phase one, with a detention time of 3-days and no mixing, the maximum reduction in cod was 23%. in the second phase, with a detention time of 2-days and complete mixing, glucose was added to the raw sewage, the reduc...

Managing the wastewater discharged from oil and shale gas fields is a big challenge, because this kind of wastewater is normally polluted by high contents of both oils and salts. Conventional pressure-driven membranes experience little success for treating this wastewater because of either severe membrane fouling or incapability of desalination. In this study, we designed a new nanocomposite fo...

Oily wastewater discharge to water bodies can have many negative consequences, especially on the marine ecological environment. Although there are numerous techniques for treating oily wastewater, this paper aims introduce and evaluate potential of fractional freezing (FF) process as a new oil–water separation technique overcome several weaknesses found in conventional methods. FF separates two...
