Efficient and Economic Selective Bromide Ions Removal and Recovery of Water

The Problem

Development of bromine compounds markets is strongly affected by new global environmental regulations that forbids the production of wastewater containing bromide that are discharged to surface water systems. Furthermore, high bromide in conjunction with high organic carbon (OC) is widely recognized to be the worst-case scenario for drinking water plants.
Inability to achieve low bromide concentrations by existing technological processes of water treatments will lead to annual addition of at least ~$200 million. Also, forbiddance of use brominated flame retardants and biocides, hydraulic fracking ban will lead to loss of hundred million dollars every year.

The Solution

We developed simple, effective, and cost-effective technology for specific removal and recovery of bromide ions from water. This cutting-edge technology removes and recovers bromide ions by electro-oxidation in the Asymmetric CDI (A-CDI) cells.

The Commercial Benefit

Our novel technology advantages are four-fold:

  • It is simple
  • It is efficient
  • It is cost-effective
  • And it meets the requirements of all regulations
