Abstract: A system for collecting mercury from feed material that can be tailings comprises: a water inlet for forming a slurry containing the tailings; at least one screen for separating tailings from the slurry to form a screened slurry; a rotatable collection chamber containing at least one plate, a drive for rotating the collection chamber for collecting mercury on the plate to provide a discharge material comprising water and treated tailings, the treated tailings containing less mercury than in the feed material.

Abstract: A system for collecting mercury from feed material that can be tailings comprises: a water inlet for forming a slurry containing the tailings; at least one screen for separating tailings greater than ¼ inch in diameter from the slurry to form a screened slurry; a rotatable collection chamber containing a plurality of plates, a drive for rotating the collection chamber for collecting mercury on the plates to provide a discharge material comprising water and treated tailings, the treated tailings containing less mercury than in the feed material.

Abstract: Various methods and systems are provided below for the treatment of wastewater. According to various embodiments, treatment of wastewater is accomplished using the oxidative power of ozone gas and the interaction between ozone gas, FOGS, and large amounts of surfactants already present in wastewaters to be treated. According to various embodiments of the invention, a combination of oxidation and UV disinfection is used to provide a fact acting treatment for wastewater. These methods and systems generally enable reduced footprint in relation to the volumes treated, reduced cost, and increased efficiency. Various alternative embodiments are also disclosed.
