... 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 bipolar membranes (BMs) were investigated to deacidify yellow passion frui ...

... increased. On analysing the reversible nature of fouling and the variations of ionic concentrations with the pH, the role of carbonate calcium precipitation was pointed out. By using classical filtration models, it was shown that the fouling mechanism could be the deposition of CaCO3 particle ...

... abundant by-product in steel-making process. It has been used as adsorbents to remove various heavy metals and the major removal mechanisms are precipitation and adsorption on the surface of metal oxide. However, the relative contribution of two removal mechanisms has not reported. In this study, th ...

... acid (EDTA), citrate (CIT)] and their concentration on the average particle size and shape of precipitated calcium carbonate was studied. The precipitation was performed in a semi-batch operated agitated vessel at constant pH by adding sodium hydrogen carbonate to a solution containing calciu ...
