Efficiency of Galvanic Effluent Treatment in the city of Rio Verde-Goiás.

The anthropic impacts on the environment, its perception and prevention are constant objects of studies aimed at improving quality life. Within this comprehensive area, process galvanization for metals generated waste was evaluated here, because is an effective alternative in protection against corrosion, also a good ally useful life metal parts although practical profitable, generates huge volume slag. This work intended to verify by atomic absorption spectrophotometry (AAS) efficiency treatment performed electroplating plant installed city Rio Verde-Goiás. acid effluents, with emphasis hexavalent chromium used passivation parts, were treated sodium metabisulfite, keeping final effluent within passive threshold disposal, it requires post-treatment liquid maintain environmental safety.
