Multistage-batch bipolar membrane electrodialysis for base production from high-salinity wastewater

Frontiers of Chemical Science and Engineering 2022, Volume 16, Issue 5,   Pages 764-773 doi: 10.1007/s11705-021-2114-2

Abstract: Bipolar membrane electrodialysis (BMED) is considered a state-of-the-art technology for the conversion of salts into acids and bases. However, the low concentration of base generated from a traditional BMED process may limit the viability of this technology for a large-scale application. Herein, we report an especially designed multistage-batch (two/three-stage-batch) BMED process to increase the base concentration by adjusting different volume ratios in the acid (Vacid), base (Vbase), and salt compartments (Vsalt). The findings indicated that performance of the two-stage-batch with a volume ratio of Vacid:Vbase:Vsalt = 1:1:5 was superior in comparison to the three-stage-batch with a volume ratio of Vacid:Vbase:Vsalt = 1:1:2. Besides, the base concentration could be further increased by exchanging the acid produced in the acid compartment with fresh water in the second stage-batch process. With the two-stage-batch BMED, the maximum concentration of the base can be obtained up to 3.40 mol∙L–1, which was higher than the most reported base production by BMED. The low energy consumption and high current efficiency further authenticate that the designed process is reliable, cost-effective, and more productive to convert saline water into valuable industrial commodities.

Effect of seawater salinity on the synthesis of zeolite from coal fly ash

Yanqing YU, Xiaoliang LI, Xiaolan ZOU, Xiaobin ZHU

Frontiers of Environmental Science & Engineering 2014, Volume 8, Issue 1,   Pages 54-61 doi: 10.1007/s11783-013-0493-4

Abstract: Seawater salinity was varied from 32 to 88 for zeolite crystallization during the hydrothermal processThe results show that seawater salinity plays an important role in zeolite synthesis with CFA duringThe products were a mixture of NaX zeolite and hydroxysodalite; seawater salinity more strongly affectedThe yield of CFA transformed into zeolite gradually rose with the increase in salinity, reaching a transformationrate of 48%–62% as the salinity increased from 32 to 88, respectively.
