Electro-Biochemical Reactor (EBR)

Biological Solution for Municipal and Industrial Nitrate and Selenium Removal

Biological treatment for water and wastewater has become an effective solution for targeted contaminant removal. With the addition of electron donors, microbes utilize dissolved nitrate or selenate for respiration. The contaminants are then converted to inert Nitrogen gas and elemental Selenium.

Why Choose EBR

Traditional biological treatments require a constant influent of carbon nutrients to supply the electrons required for respiration. This increases operating costs and promotes biofilm bloating, reducing the respiration efficiency of the microbes.

EBR systems use low-level direct voltage to supply the electrons needed by the microbes, minimizing costly reagents and improving overall reactor function.
