Removal of mercury from effluent streams

摘要: Apparatus for treatment of effluent streams containing very low concentrations and even trace amounts mercury in both elemental form as mercuric ion. The stream is passed through a closed vessel having bed reactive metal particles, such Zinc, magnesium aluminum, iron, so that the forms an amalgam on surface. regenerated recovered by heating while under vacuum condensing vaporized mercury. lower temperature permitted reduced pressure absence air precludes oxidation clumping granules.
