Abstract
A method for treating waste fluids to remove selected chemicals such as minerals and metals wherein a bacterial culture that will attach to a selected chemical is transferred to a nutrient medium for a time period sufficient to produce satisfactory bacterial cell growth. The bacterial cells are then attached to a porous fiber webbing supported in a suitable container and the nutrient medium is then withdrawn from the container and waste fluid introduced into the container for a period of time sufficient to attach the chemical to the bacterial cells. The waste fluid is then removed from the container and the chemical separated from the fiber webbing.
