Chemical use Scale inhibitor and ,acid, may be required for process control to prevent scaling. Periodic chemical cleaning is typically conducted using ,acid,, caustic, EDTA, disinfectant, or other anti-scaling chemicals. Expected lifetime of critical components ED membrane lifetime is estimated to be 4-5 years.

Optimal Treatment of Hypersaline Industrial Wastewater via ...
Optimal Treatment of Hypersaline Industrial Wastewater via ...

The wastewater from a fluid catalytic cracking refinery is difficult to treat because of its high salt content. An optimized bipolar membrane electrodialysis (BMED) strategy to dispose of this wastewater is proposed, and its effect is studied via a combination of experiments and simulations.

Reclamation of Aniline Wastewater and CO2 Capture Using ...

In this work, a novel bipolar membrane electrodialysis (BMED)-based process was proposed to treat aniline wastewater and simultaneously capture CO2. Such a process consists of predesalinization, CO2 capture, and aniline removal in three steps.

Ammonium nitrate wastewater treatment by coupled membrane ...

Abstract. A process coupling membrane electrolysis and electrodialysis is implemented to treat ammonium nitrate wastewater. Membrane electrolysis produces ammonia and nitric acid while electrodialysis reconcentrates the depleted salt solution. Ammonia is removed continuously by in situ stripping; thus allowing gas production with a constant current ...

The Electrodialysis Advantage | WWD

Electrodialysis, is a membrane separation process in which ions are transported through semipermeable membranes under the influence of an electric field from one solution to another in order to reduce the ionic content of water. The ,electrodialysis, stack is composed of alternately constructed cation and anion exchange membranes to form dilute and concentrate chambers.

Treatment of Ammonia-Nitrogen Wastewater by Electrodialysis
Treatment of Ammonia-Nitrogen Wastewater by Electrodialysis

The ammonia-nitrogen ,wastewater, was purified by using ,electrodialysis, (ED) device in this paper. The NH4Cl solution was used as the artificial ammonia-nitrogen ,wastewater,. Various unsteady factors in the experiment may cause the concentration polarization phenomenon, which may have negative effect on ED cell performance and its lifetime. The limiting voltage was confirmed as 12V in this study.
