Background and Objectives: Red beet juice, a potential source of valuable nutrients, is widely used as a colorant in food industries. In recent years, to avoid reduction of nutritional values of the red beet during concentration by thermal processing, an osmotic distillation (OD) technique has been suggested. Therefore, the major aim of the present study was to investigate effects of the flow r...
The gas-liquid membrane contactor (GLMC) is a promising alternative gas absorption/desorption configuration for effective carbon dioxide (CO2 ) capture. The physicochemical properties of membranes may synergistically affect GLMC performances, especially during the long-term operations. In this work, commercial polypropylene (PP) and polyvinylidene fluoride (PVDF) hollow fiber (HF) membranes wer...
Membrane distillation (MD) is a promising hybrid thermal-membrane separation technology that can efficiently produce freshwater from seawater or contaminated wastewater. However, the relatively low flux and presence of fouling wetting agents in feed solution negate applicability MD for long term operation. In recent years, 'two-faced' membranes Janus have shown potential to decrease problem com...
