Identification of key factors affecting the organic fouling on low-pressure ultrafiltration membranes
The fouling behavior of the hollow fiber ultrafiltration (UF) membrane by the mixtures of dissolved organic matters (DOMs) has been systematically investigated. The organic foulants included humic acid (HA), bovine serum albumin (BSA) and sodium alginate (SA), which represented humic substances, proteins and polysaccharides, respectively. According to the experimental results, the filtration pr...
متن کاملUltrafiltration through Collodion Membranes
It is obvious that the factors considered in this paper render data obtained by ultrafiltration open to criticism unless they are checked by other methods and precautions are taken for the elimination of the vitiating effects which have been described. As regards the mechanism of ultrafiltration, the view of a sieve-like action as most experimental evidence indicates, is adequate, if all the fa...
متن کاملclarification of sour orange juice by ultrafiltration: optimization of permeate flux and fouling resistances using response surface methodology
the turbidity of sour orange juice after juice extraction affects on quality, shelf-life and concentration of juice. therefore, juice clarification is an important operation in the fruit processing industry. the goal of this study was evaluating the effect of membrane operation parameters including pressure (120-220 kpa) and temperature (25-35 ºc) on the permeate flux and hydraulic resistance o...
متن کاملFouling and rejection behavior of ceramic and polymer-modified ceramic membranes for ultrafiltration of oil-in-water emulsions and microemulsions
The effectiveness of poly(vinylpyrrolidone) (PVP)-modification of a zirconia-based ultrafiltration membrane was investigated for the treatment of oil-in-water (o/w) emulsions. Fouling, hydraulic permeability, flux decline, and solute rejection for modified and native membranes were evaluated using a diagnostic o/w emulsion as well as an emulsion prepared using a commercial cutting oil. The nati...
متن کاملFouling Mechanism Study of Nanoporous Membrane by Ultrafitration of Whey Proteins
One of the barriers during whey filtration using UF membrane is the fouling phenomenon of the membrane, which is caused by whey proteins. In this work, the UF membranes were prepared using polysufone (PSf), dimethyl formamide (DMF), 1 wt.% poly vinyl pyrrolidone (PVP) and different concentrations of LiCl via phase inversion induced by immersion precipitation. The prepared membranes were charact...
