Demineralization

In this paper, nanofiltration (NF) combined with continuous variable volume diafiltration (CVVD) of cottage cheese whey (also known as acid whey) was investigated to simultaneously concentrate and partially demineralize it. The experiments were carried out in a laboratory NF equipment using a flat s

Transport of basic amino acids during the electrodialysis is studied and the procedures of their recovery from various mixtures are suggested. Peculiarities of basic amino acids transfer through the ion-exchange membranes are closely connected with their amphoteric nature and high values of isoelect

In this work, the membrane technique of nanofiltration (NF) was used to carry out partial demineralization of whey and milk ultrafiltration permeate (MUP). The experiments were performed in a completely automated NF pilot plant. An aromatic polyamide spiral wound membrane supplied by Osmonics (USA)

The application of electrodialysis technology in demineralization of glutamine fermentation broth was studied. We used the one-dimension Nernst–Planck equation to describe the process of demineralization of the glutamine fermentation broth system, did the theoretical calculation on the demineralizat

Good characterization of raw water quality and subsequent identification of the most appropriate pre-treatment are not sufficient to ensure successful functioning of a reverse osmosis plant. The Tan Tan demineralization plant was set up in July 2003 for 20 l/s production capacity. The brackish water

We have used electrodialysis for the separation of amino acids, mineral ions and sugars. It is an important problem at the last stages of biotechnological production of amino acids. We consider two effects that allow one to solve the problem of separations. The “barrier” effect makes it possible to

It is common practice in electrodialysis demineralization of calcium hydrocarbonate natural waters to restrict the current density by the limiting diffusion one. Exceeding this value causes the irreversible water dissociation at the interface of the anion-exchange membrane and solution and selective
