Implantação de um programa de gerenciamento de resíduos químicos e águas servidas nos laboratórios de ensino e pesquisa no CENA/USP Establishment of a management program for chemical residues and waste water, generated in laboratories of the centro de energia nuclear na agricultura (CENA/USP)

The aim of this work is to establish a program for the treatment of chemical residues and waste waters at the Centro de Energia Nuclear na Agricultura (CENA/USP), for environmental preservation and training of staff. Five tons of stored residues and the ones currently generated in the laboratories have to be treated. Rational use of water is also part of the program. The traditional purification by distillation has been replaced by purification with ion exchange resins. Lower energy consumption and better water quality were achieved.
