The present invention is directed to systems and methods of treating wastewater. The present invention may include a method of treating such wastewater comprising selenium in the form of water soluble selenates, selenites, and/or selenides, the method including: a chemical/biological treatment process, causing the water soluble selenates, selenites, and/or selenides in the wastewater to be converted into insoluble elemental selenium; and a physical treatment process, trapping the insoluble elemental selenium in a filtration device. Systems and methods in accordance with the present invention may also include a system for including: one or more chemical/biological treatment reactors, the one or more chemical/biological treatment reactors configured to cause the water soluble selenates, selenites, and/or selenides in the wastewater to be converted into insoluble elemental selenium; and one or more physical treatment devices, the one more physical treatment devices configured to trap the insoluble elemental selenium in a filtration device. |
