Concentration of sucrose solutions via vacuum membrane distillation

Morphological and hydrophobic modifications of PVDF flat membrane with silane coupling agent grafting via plasma flow for VMD of ethanol–water mixture

“…When first patented by Bodell in 1963 [1], MD is accepted as a low cost, energy saving separation process compared to conventional separation processes, such as distillation and reverse osmosis (RO) [2]. The potential applications of MD process for production of high-purity water [3], concentration of ginseng extracts aqueous solution [4], cane sugar solution [5]or other non-volatile aqueous solutions [6,7]and separation of volatile component [8,9] are well recognized. Although the concept of MD has been known for about 50 years, this process is still in its development stage [10].…”

Fouling resistance in concentrating TCM extract by direct contact membrane distillation

“…The interest in concentrating various solutions containing thermally labile components by MD or osmosis membrane distillation (OMD) has risen rapidly in recent years. The feasibility of concentrating various kinds of aqueous solution, such as orange juice [2,3], apple juice [4][5][6], sugarcane juice or sucrose solutions [7][8][9], fructose solution and grape juice [10], whey protein solution [11] and acid [12][13][14], by direct contact membrane distillation (DCMD), vacuum membrane distillation (VMD) or OMD has been verified in previous studies.…”

Characteristics analysis of cross flow vacuum membrane distillation process

“…The cross flow effectively reduced the temperature and concentration polarizations so that the high permeation flux was obtained and the membrane fouling was mitigated. In their studies, the maximum permeate flux reached 79 kg/m 2 h. Guijt [8,9], Wu [10], Asheh [11] and Wang [12] carried out membrane distillation experiments using hollow fiber membrane module respectively. Good results have been obtained.…”
