A biological filtration system includes a reservoir configured to receive an aqueous liquid, a multiplicity of polymeric container closures in the reservoir, a fluid inlet fluidically coupled with the reservoir, and a fluid outlet fluidically coupled with the reservoir. The fluid inlet is configured such that an aqueous liquid provided to the reservoir via the fluid inlet contacts the multiplicity of polymeric container closures. The polymeric container closures support biofilm growth. Treating the aqueous liquid provided to the biological filtration system includes contacting the polymeric container closures with the aqueous liquid, growing biofilm on the polymeric container closures in contact with the aqueous liquid, thereby removing contaminants from the aqueous liquid to yield a treated aqueous liquid, and removing the treated aqueous liquid from the biological filtration system. The polymeric container closures may be reclaimed following consumer or industrial use, thereby conserving resources and reducing costs related to biofilm carriers. |
