Abstract With the improvement of environmental protection requirements, economical and efficient oily wastewater treatment methods have become a research hotspot. At same time, characteristics microbubbles (large specific surface area, high zeta potential, rises slowly) make it very widely used in various fields, including wastewater. There are many to generate microbubbles, each method has its...

Cork, a material with great economic, social and environmental importance in Portugal, is also a good oil sorbent that can be used in the remediation of oil spills. The oil-impregnated cork can be easily removed, but requires further treatment. In the case of vegetable oil spills, anaerobic digestion may be a potential solution. This study aims to evaluate the effect of adding cork contaminated...

In recent years, industry has increased and with it the amount of oily wastewater, which are considered hazardous waste because they contain various types heavy metals oils that endanger environment human health. last twenty there been research on new technologies to treat wastewater as efficiently environmentally friendly possible. A approach treatment is application electrochemical processes ...

This study focused on the evaluation of the specific biological heat potential (hb) of a food-processing artificial wastewaterin the autothermal thermophilic aerobic treatment (ATAT) system. A novel experimental method was developed to evaluate the hb value by using the heat balance model under the steady state. This system was daily fed with oily and artificial wastewater at 21,460 mg l(-1) CO...

In this study, a novel flocculant was prepared by an inorganic polymetric flocculant (IPF) polysilicate ferroaluminum sulfate (PSFA) and rectorite (REC). The structure of the PSFA-REC composite was characterized by Fourier transform infrared (FT-IR) spectroscopy and X-ray diffraction (XRD), in order to determine the optimal temperature. The flocculation test was made at 25 , 45 and 65 , the res...
