The photocatalytic degradation of the model pollutant carbamazepine (CBZ) was investigated under simulated solar irradiation with an N-doped TiO₂-coated Al₂O₃ photocatalytic membrane, using different water types. The photocatalytic membrane combines photocatalysis and membrane filtration in a single step. The impact of each individual constituent such as acidity, alkalinity, dissolved organic m...
Separate treatment of high-nutrient sidestream is an efficient and cost effective way to decrease the loading on the main plant, resulting in lower effluent nutrient concentration. This study investigated the use of a combined forward osmosis-membrane distillation (FO-MD) system for the removal of nitrogen present in high concentration in sidestream from anaerobic digestion process. The combine...
The production of beer is characterized by the consumption of large volumes of fresh water. Whereas, cleaning operations are the highest water consumption demanding activities in breweries. Commonly “Cleaning In Place” (CIP) systems are used in closed processing lines. These consist of automatic cleaning and disinfection programs based on a succession of several solutions of water, cleaning che...
Polyvinylidene fluoride (PVDF) membranes blended with various amounts of MWCNT-ZnO (0.1%–3%) nanocomposites were prepared by the phase inversion method. The effect blending on membrane structural and morphological properties was investigated XRD, FT-IR SEM techniques. Contact angle measurement reveals that hydrophilicity increases increase nanocomposite content; a reduction contact from 103° fo...
The economic impact of fouling in spiral wound membranes is not yet well explored. There has been an established assumption that the cost membrane processes significant, but this hypothesis thoroughly evaluated. We conducted analysis on seven full-scale installations, four nanofiltration (NF) and three reverse osmosis (RO), to estimate industrial plants. was calculated detail, including costs i...
The leather industry is characterized by the production of a huge amount wastewater with high organic/inorganic charge, causing widespread water and soil pollution. Pressure-driven membrane operations bioreactors have long been proven to be valid approach for treatment tanning wastewaters aimed at recovery raw materials as well removal toxic environmentally harmful substances. Such processes, o...
Due to the low separation efficiency and poor stability, traditional polymer filtration membranes are prone be polluted difficult reuse in harsh environments. Herein, we reported a nanofibrous membrane with honeycomb–like pore structure, which was prepared by electrospinning electrospraying. During electrospraying process, addition of polydimethylsiloxane fumed SiO2 formed pores electrostatic r...
