“…Cleaning could not restore the initial fluxes. Similar results were obtained by Hinkova et al (Hinkova et al, 2002). Beside application of membrane separation processes in sugar juice purification, there where attempts to use reverse osmosis to recycle pulp press water (Bogliolo et al, 1996) or to recover pectin from sugar beet pulp (Hatziantoniou & Howell, 2002).…”

“…Apart from using polymeric membranes, the use of inorganic -ceramic and metallic-membranes to achieve commercially interesting fluxes and permeate purities has been investigated. Hinkova et al (Hinkova et al, 2002) observed that the filtration of diluted raw juice concentrate with ceramic membrane led, at a pilot scale, to a significant decrease in colloids and colour matters resulting in juice suitable for direct crystallization. Schrevel (Schrevel, 2002) compared the results obtained on different membranes in different module configurations.…”

“…However, DK membrane performed slightly better than DL membrane due to the smaller pore radius, according to the literature (Bargeman et al, 2005). Considering this behavior, both membranes represent a great potential opportunity for the food industry to recover sugars; in this case, for example, glucose from effluents from the winery industry (Hinkova et al, 2002;Ioannou et al, 2013;Salehi, 2013). As J v is proportional to ΔP n (eq.…”

“…Because of this combination they are effective for the separation of small organic solutes and salts from a mixture. NF is currently used in water treatment, chemical and food processing industries, to concentrate, fractionate or purify aqueous solutions of organic solutes (Molecular Weight (MW): 100-500 g/mol), textile dyes, heavy metals, and mixtures of monovalent/multivalent solutions Hinkova et al, 2002;Jiao et al, 2004;Luo and Wan, 2013;Ong et al, 2014;Zhu et al, 2014). Different phenomena appear when sugar solutions, in contrast to pure water, are filtered.…”

In this work two commercial membranes, DK and DL, were used to concentrate glucose solutions. Membranes were characterized according hydrophobicity, thickness, porosity, and hydraulic permeability. The influence of pressure and concentration of glucose on the permeate flux and rejection were studied. Both membranes presented a great potential for the food industry due to their high rejection of glucose. The osmotic pressure model was combined with film theory and the real driven force was calculated taking into account the osmotic pressure and the concentration polarization. Both phenomena influenced the process (concentration polarization only in the most dilute solutions at low pressure) and the permeability for glucose solutions was similar to the hydraulic permeability. A mathematical model based on the Donnan-Steric Pore Model was used to determine the pore radius and the effective thickness of both membranes. As the concentration inside the pore (needed for the calculations) is difficult to measure experimentally, various alternatives wereproposed. The average of the concentration at the interface and permeate best fitted the experimental data. The model was applied successfully; the maximum error was 8% within the range of concentrations (5 -100 g/L) for the DL membrane and 5% for the DK membrane up to 50 g/L.Page 2 of 26 A c c e p t e d M a n u s c r i p t 2 HighlightsTwo membranes were characterized and used to concentrate glucose solutions Both membranes presented a great potential due to their high rejection of glucoseThe osmotic pressure and concentration polarization effects were taken into accountMembrane pore radius and effective thickness were determinedThe model fitted successfully the experimental data with maximum errors of 8%

“…Schrevel 2 found that in order to achieve a suffi ciently high purity of juice after fi ltration, a membrane with a cutoff from 10 kDa to 0.1 mm was needed. Similarly, Bubnik 3 and Hinkova et al 4 obtained good results using a ceramic membrane with a pore size of 20 nm. Sarka et al…”

Ultrafi ltration of diffusion juice is a method that can reduce environmental pollution during the production of sugar. A by-product (concentrate) of ultrafi ltration contains a large amount of sucrose, but due to its properties, it is diffi cult to manage. The aim of this study was to determine the effects of the temperature used during drying of diffusion juice concentrates on the content of certain components and characteristics of resultant preparations. Diffusion juice obtained from one of the Polish sugar plants was subjected to ultrafi ltration and the obtained concentrates were dried in a spray dryer. In the dried samples, the following parameters were analyzed: dry mass, sucrose, total ash, protein, crude fi ber and color. It has been declared that the degree of concentration and drying temperature infl uenced the chemical composition and the properties of the dehydrated diffusion juice concentrates. An increase in drying temperature was accompanied by the increased content of dry mass, protein, ash and fi ber content in the preparations. The greater the degree of juice concentration, the greater was the content of dry mass, ash, and fi ber. Inversely, the greater the degree of juice concentration, the lower the content of sucrose. The brightest color of the dehydrated product was observed at the drying temperature of 200 o C. Spray-drying may be used for waste management after the diffusion juice membrane fi ltration, and the resultant preparations might be used in the production of feedstuff or food industry in general e.g. as sucrose source, in fermentation processes or in microorganisms propagation.
