Abstract
Highly porous, adsorbent biocatalyst beads of synthetic organic polymer have powdered activated carbon dispersed throughout the polymer and a biocatalyst, such as bacteria, located within macropores of the beads. The beads are used for remediation of contaminated aqueous streams. The biocatalyst can consume adsorbed organic contaminants and convert them into harmless gases, while continuously renewing the adsorptive capacity of the activated carbon.
