The present embodiments generally relate to methods and compositions for the removal of selenium from a fluid in need of treatment, such as, for example, industrial wastewaters. The methods and compositions for the removal of selenium generally comprise the use of one or more coagulants, such as at least one iron-containing coagulant, and one or more reducing agents, such as at least one sodium sulfite-based reducing agent.

Methods and compositions for treating industrial wastewater

Methods for removing one or more contaminants from an aqueous stream comprising: adding one or more hydraulic binders and one or more promoters to the aqueous stream, and separating the contaminants from the aqueous stream are provided. The methods may be used for removing contaminants that are arsenic-based, selenium-based, cadmium-based, zinc-based, mercury-based, iron-based, chromium-based and/or phosphate-based.
