Recovery of heavy metals from produced water
WebbThis can increase the recovery rate by 30-60%, compared to the 5-15% typically recovered in the primary stage. Produced water is the water byproduct that comes out of the well with the crude oil during this EOR process. The composition of produced water varies widely from well to well. It typically contains soluble and non-soluble oil/organics ... WebbThe accumulation of heavy metals by microbial biomass with high surface area-to-volume ratio holds great potential for heavy metal removal in both soluble and paritcular forms, especially when the heavy metal concentrations are low (<50 mg/L). E. coli and B. subtilis are effective agents for metal removal. We further investigated the effect of pH, …
