Electrodialysis (ED) with ion-exchange membranes represents one of the most important membrane methods of treatment of industrial effluents discharged. Attention to the deep ecological aspect of this method implies favourable forecasts for its future. Preparation and analysis of the properties of as

Observations via a video camera of the behavior of the bubbles produced in a chlor-alkali membrane cell with parallel-plate electrodes during sodium chloride electrolysis allowed us to justify the use of 1D model for the calculation of current density distribution. Experimental current density measu

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 high acidity of passion fruit limits its addition in food preparation and gives poor aroma and flavour products. The reduction of the acidity of the fruit juice can avoid this problem. Various methods such as calcium precipitation, ion-exchange resins and electrodialysis (ED) with homopolar and

In electrophoretic separators, a porous membrane is used to put into contact two flowing liquids between which an electrically driven mass transfer takes place. As far as charged solutes are concerned, the mass transfer can be affected by electrostatic interactions taking place at the membrane solut

The separation performances of divalent ions (Ca2+ and Mg2+) by electrodialysis (ED) were compared using a constant voltage mode of operation. For the batch tests, TS-1-10 ED equipment was employed. During the experimental studies, the effects of electrical potential applied and flow rate of streams

A process is set up to treat ammonium nitrate wastewaters. It couples membrane electrolysis and electrodialysis. Membrane electrolysis regenerates nitric acid and ammonia while electrodialysis is suitable to extract a depleted stream from the salt circuit and to recycle a concentrated stream. The me

Electrodialysis (ED) is an efficient process for the treatment of drinking water with high nitrate concentration. However it achieves only a transfer of pollution by producing concentrated brines. This study demonstrated the feasibility of ED brine denitrification in a membrane bioreactor (MBR). The

Cellulose solution, as a model waste water was hydrolysed in a special, jacketed membrane bioreactor by Celluclast enzyme preparation to produce glucose. Stainless steel microfiltration tube membrane covered by a hairy pelt cloth was applied, which provided a surface for simultaneous adsorption of t

Thin-layer molecularly imprinted polymer (MIP) composite membranes for selective binding of triazine herbicide desmetryn from aqueous solutions were developed using photoinitiated copolymerization of 2-acrylamido-2-methyl1-propane sulphonic acid and N,N′-methylene-bis-acrylamide in the presence of t
