Membrane separation is an alternative separation technology to the conventional method of filtration. Hence, it has attracted use in the purification and concentration of Chinese Herbal Medicine Extracts (CHMEs). The purpose of this work was to study the process of microfiltration of Tongbi liquor (TBL), a popular Chinese herbal drink, using ceramic membranes. Zirconium oxide and aluminum oxide...

Orange press liquor is a by-product generated by the citrus processing industry containing huge amounts of natural phenolic compounds with recognized antioxidant activity. In this work, an integrated membrane process for the recovery of flavonoids from orange press liquors was investigated on a laboratory scale. The liquor was previously clarified by ultrafiltration (UF) in selected operating c...

Same-day microbial water quality assessments are not possible with standard methods, which increases the possibility of public exposure to fecal pathogens. This study examined the efficacy of high-volume hollow fibre ultrafiltration coupled to biosensor detection for enterococci in marine waters to allow same-day public notification of poor water quality. Fifty-six 1001 ultrafiltered samples an...

In this work, we present the application of exergy analysis in the evaluation of the ethanol steam reforming (ESR) process in a catalytic membrane reactor (CMR) containing Pd-Ag membranes sandwiched by PdRh/CeO2 catalyst to produce fuel cell grade pure hydrogen (no sweep gas). ESR experiments were performed at T=873-923 K and P=4-12 bar. The fuel was a mixture of ethanol and distilled water wit...

Waters located at greater depths usually exhibit high mineral content, which necessitates the use of closed systems, i.e. re-injecting them into the formation after recovering the heat. This significantly reduces investment efficiency owing to the need to drill absorption wells and to perform anti-corrosion and anti-clogging procedures. In this paper, possibilities for the efficient utilisation...

AIM To develop an automated, high throughput extraction protocol in order to produce database eligible profiles from fingerprints and other low copy number (LCN) DNA sources. METHODS Extraction of either purified control DNA or buccal cells, for example, with commercial kits was compared to extraction with a simple digestion buffer and a subsequent concentration and purification. Results were...

Hydrogen selective Pd and Pd alloy membranes can improve the efficiency and cost effectiveness of the coal gasification process by recovering high purity H2 from the syngas. Also, the high pressure CO2 in the retentate reduces the cost of carbon capture required for carbon sequestration. However, small quantities of H2S present in the gas stream poison the Pd membranes and reduce the hydrogen p...

and non-uniformity of the oligosaccharides themselves, would indicate that the toxicity is a property of a number of molecules. For this reason large-scale chromatographic techniques were avoided since they would result in a distribution of toxicity across the chromatographic profile. Instead the role of carbohydrate was investigated by the selective removal of the sugar residues glycosidic lin...

Bioactive milk peptides are reported to illicit a range of physiological benefits and have been proposed as potential functional food ingredients. The objective of this study was to characterize the anti-inflammatory properties of sodium caseinate (NaCAS), its enzyme hydrolysate (EH) and peptide-enriched fractions (5 kDa retentate [R], 1 kDaR and 1 kDa permeate [P]), both in vitro using a Caco-...

Nanofiltration can be used to separate succinic acid (SA) from other organic acids in a fermentation broth. However, commercial nanofiltration membranes insufficiently selective since some produced have similar molecular weights. SA production biomass entails separation of the concomitantly such as acetic acid, formic pyruvic etc. In this study, five were tested for rejection and selectivity un...
