Ultrafiltration

The ability to produce functional food ingredients from natural sources becomes increasingly attractive to the food industry. Antimicrobial (bioactive) ingredients, like peptides and proteins, can be isolated from hydrolysates with membrane filtration and/or chromatography. Electro-membrane filtrati

The application of laccase and manganese-dependant peroxidase (MnP) from Trametes versicolor to facilitate removal of aromatic hydrocarbons from a petrochemical industrial effluent was investigated. The enzymes were immobilised onto polysulphone ultrafiltration membranes thus facilitating enzyme-sub

Ultrafiltration (UF) has been accepted as a versatile membrane separation process for water purification and wastewater treatment in recent years. In this paper the UF separation behaviour of oil-in-water emulsion used usually for metalworking fluids was studied. The effect was investigated of diffe

In this paper the results of an applied research project within the scope of the transfer centre 4031 funded by the German Research Foundation (DFG) are presented. In cooperation with the Henkel Genthin GmbH investigations have been made on the application of UF/NF membrane processes for the separat

The potential of using the integrated membrane system based on ultrafiltration (UF) and nanofiltration (NF) in purification of effluents from a cable factory was investigated. The UF experiments were performed using tubular membranes taking into consideration the composition of the treated effluents

The experimental results of the pilot scale application of different membrane technologies, supported by clariflocculation and ozonization, for textile wastewater reuse are described. The investigation has been carried out by treating two different textile effluents: a secondary effluent coming from

The application of ultrafiltration technology for drinking water production has shown rapid development from the beginning of the 1990s. There has been a constant cost reduction of this technology over the last ten years allowing evolution (new polymers, new module designs, etc.), and a decrease of

Ultrafiltration has been investigated for the concentration of diluted biopolymer solutions. Trials were realized with membranes of different molecular weight cut off (MWCO) and configuration modules. Results indicates that hollow fiber module gives the best results with the membrane of 6 kilodalton

Evaluation of ultrafiltration performance for the purpose of isolation of clavulanic acid from fermentation broths was carried out using two tubular ceramic membranes with molecular weight cut-offs (MWCO) of 15 and 150 kDa and two flat sheet organic membranes with MWCO of 20 and 5 kDa in order to es

Affinity ultrafiltration can provide stereoselective separations using a large macroligand to selectively bind and retain one of the enantiomers. The detailed binding interactions can be strongly influenced by the solution pH and salt concentration, although there is currently little understanding o
