Improving electrodialysis separation efficiency of minerals from acid whey by nano‐filtration pre‐processing Open
Acid whey (AW) contains valuable minerals, such as calcium and magnesium. Electrodialysis (ED) is an efficient technology to recover these minerals; however, the less nutritional sodium will also be recovered during ED. AW was processed by…

Recovery of Hydrochloric Acid from Industrial Wastewater by Diffusion Dialysis Using a Spiral-Wound Module Open
In the present study, the possibility of using a spiral-wound diffusion dialysis module was studied for the separation of hydrochloric acid and Zn2+, Ni2+, Cr3+, and Fe2+ salts. Diffusion dialysis recovered 68% of free HCl from the spent p…

An Investigation on the Application of Pulsed Electrodialysis Reversal in Whey Desalination Open
Electrodialysis (ED) is frequently used in the desalination of whey. However, the fouling onto the membrane surface decreases the electrodialysis efficiency. Pulsed Electrodialysis Reversal (PER), in which short pulses of reverse polarity …
