Electrodialysis (ED) using two-stack configurations with homopolar or bipolar membranes was investigated for deacidification of tropical fruit juices (passion fruit, mulberry, naranjilla). The objective was to develop a mathematical treatment for ED

The reduction of acidity of four tropical fruit juices, passion fruit, castilla mulberry, najanrilla and araza, was investigated by using the electrodialysis (ED) process. Two stack configurations using homopolar membranes and three compartments (ED3

Too many or too few fluoride ions in drinking water are harmful to the consumer's health. The acceptable fluoride concentration is generally in the range of 0.5 to 1.5 mg.L−1. In the present study, Donnan dialysis (DD) with an anion-exchange membra

Excess or lack of levels of fluoride in drinking water being harmful to human health, the concentration of F− ions must be maintained in the range 0.5 to 1.5 mg l−1. The purpose of this study is to apply Donnan dialysis (DD) for fluoride removal

Electrodialysis (ED) with bipolar membranes (BPM) was applied for the extraction of amino acids in an electrically neutral form. Under voltage, BPM split water, generating hydroxyl ions at the anodic side and protons at the cathodic side. The use of

An electrodeionization process has been developed using ion-exchange textiles (EDIT) instead of ion-exchange resins as currently used for the production of ultra-pure water. The study was carried out with a laboratory pilot. Each membrane had an acti
