One of the main by product obtained during beer production in the brewing industry is brewer's spent grains (BSG). They are rich in cellulose, hemicellulose, lignin, and proteins. The aim of the work is to explore the effect of acid and alkali pre-treatments on BSG by studying the solubilisation behaviour of the organic molecules. BSG is...

Flat sheet membranes made of polyvinyldene fluoride (PVDF) were prepared via nonsolvent induced phase separation (NIPS). The focus of this work was concentrated on the effect of the support structure and material on the morphology and on the distillation performance of the final membranes. To this end, various membranes were prepared casting a...

The production of olive oil generates olive mill wastewater (OMW) which essentially derives from the processing, treatment and pressing of olives in mills. Traditional milling processes require a quantity of water varying between 40 and 120 L per quintal of pressed olives, generating a considerable amount of wastewater. It is thus necessary to...

In recent years, hydrothermal treatment has been considered as among the most promising option for sludge solubilisation and carbon recovery in terms of sludge management. In this study, the effect of different individual hydrothermal operating conditions like temperature (110–250 °C), sludge pH (6–13) and reaction time (0.5–3 h) were varied to...

Ceramic membranes prepared with flat sheet configuration using local materials, iron ore and bentonite, are reported in this investigation. The feedstocks used were fully characterized using X-ray diffraction (XRD), thermogravimetric analysis (TGA), scanning electron microscopy coupled with energy dispersive spectroscopy (SEM-EDS) and laser...

BACKGROUND: Catalysts based on alumina-supported metal oxides are of crucial importance in the field of heterogeneous catalysis for several applications requiring tuning of surface acidity. RESULTS: In this work, the effects of K+, Ca2+ and La3+ cation doping have been evaluated on a well-characterized commercial gamma-Al2O3 through...
