Interest in desalination using membrane processes has increased with the growth of membrane science and technology. Fouling of ion exchange membranes is one of the most significant considerations in the operation of the electrodialysis desalination process. The influence of the adsorption capacity o

One of the key transport parameter—permeability, is being used as an intrinsic characteristic of membrane for reverse osmosis process prediction. In this study, the prediction of reverse osmosis process in terms of boron rejection was carried out in two steps. First, the permeability of boron existi

Electrical impedance spectroscopy was used for the characterization of electroregeneration in a continuous electrodeionization (CEDI) system packed with cation-exchange resin (CIX). CEDI process usually operates in two regimes of enhanced transfer and electroregeneration. The current efficiency decr

Novel integrating electrochemical processes with electrodialysis reversal (EDR) and electro-oxidation were designed as advanced water treatment equipment to meet the most rigorous specifications for the existing wastewater treatment facility of secondary nonradioactive system. Pilot tests of these p

Performances of electromembrane systems were investigated for removal of the hardness materials in a tap water. Six cells of ED, EDR, and EDIR systems with an electrode area of 12.5 cm ´ 8.0 cm were operated. The results showed scaling formation due to water dissociation on the surface of cation exc

In light of broad use of the electrodialysis (ED) processes, it has become crucial to minimize its operating costs. The total cost of the ED process consists of energy, investment and maintenance costs. Energy cost increases linearly with the current density while the investment cost decreases with
