A system may include a reactor, in which an anaerobic environment exists, that includes a slurry of at least contaminated water and a mixed bacterial culture of facultative bacteria and anaerobic bacteria. The mixed bacterial culture may be suspended within the slurry. The contaminated water may include contaminants associated with a non-metal, a metal, or a metalloid. The mixed bacterial culture may react with the contaminated water to reduce or remove the contaminants from the contaminated water to create a treated slurry. The reactor may output the treated slurry. The system may also include a filtration device to receive the treated slurry; remove, from the treated slurry, the mixed bacterial culture and the contaminants, reduced or removed from the contaminated water, to create treated water; and output the treated water. The system may also include an aeration device to add dissolved oxygen to the treated water, and output the treated water. The system may also include a reaction device where iron or aluminum salts are added to remove phosphorous, selenite, arsenate, or other contaminants which adsorb onto iron or aluminum oxyhydroxide solids. The system may also include a filtration device to remove the solids from the water, and output the treated water. |
