Biodiesel as alternative for conventional diesel fuel is mainly produced by the catalytic reaction of triglycerides with an alcohol. In this work, the purification of biodiesel was carried out with two lab-made solvent-resistant ...

In this paper, soybean oil deacidification and hexane removal using laboratory scale solvent resistance nanofiltration membranes based technique is presented. Composite nanofiltration membranes made of different polymers ...

Water reclamation and reuse are economically and environmentally important issues for industries. Costly and ineffective treatments such as coagulation, flocculation, and/or biological treatment are the most widely used ...

The present work demonstrates the potential of oil/n-hexane miscella separation from a local factory via a hybrid nanofiltration-evaporation process. In the membrane separation, solvent resistance nanofiltration (SRNF) ...

Polymeric membranes are an interesting alternative for the nanofiltration/desalination processes of marine and brackish water bodies, aiming to increase the availability of drinking water. However, these processes are ...

Vegetable oil extraction, as performed today by the oilseed-crushing industry, usually involves solvent extraction with commercial hexane. After this step, the vegetable oil–hexane mixture (miscella) must be treated to ...

The tanning industries are characterized by generating large volumes of wastewater. The largest volume of effluents comes from the tanning stage and has a high concentration of tannins and a low ratio tannin/non-tannin ...

Nowadays, fluoride contamination of drinking water is a major problem for various countries, because high concentrations of fluoride pose a risk of dental and skeletal fluorosis. Over past years, membrane nanofiltration ...

Pharmaceutical compounds represent a diverse set of biologically active molecules used in human and veterinary medicine. The increase in the consumption of these drugs contributes to the constant occurrence of these compounds ...
