Bench-Scale EBR Sulfate Removal Case Studies

​The EBR technology has been evaluated for sulfate reduction during six laboratory bench-scale studies. In each case, the EBR technology has been demonstrated to meet sulfate discharge goals, which varied between 250 mg/L and 500 mg/L. These projects spanned various water chemistries and different levels of co-contaminants, such as nitrate-N, which varied between <1 to 207 mg/L. Testing of the different waters through Inotec’s tiered testing protocols provided a stabilized microbial population, optimized nutrients/amounts, and a starting hydraulic retention time (HRT) to stabilize the pilot system EBR microbial population and provide a fast system startup.

Pilot-Scale EBR Sulfate Removal Case Study

A pilot trial implemented at a mine in Central America successfully validated sulfate and nitrate removal from mining waters. Validation testing showed that the EBR system met both nitrate/nitrite and sulfate discharge goals. System stress testing required to fully evaluate minimum and optimal retention times and nutrient optimization was not able to be completed due to site technical issues and local social complications.
