Integrated Treatment of Regeneration Effluents from Decolorization Units in the Sugar Refinery
Bento, J., Machado Santos, J, et.al. 1990. Sugarcane refinery using a resin decolorization unit discharges between 6m3 and 9m3 of colored brine per 100 tonnes of sugar produced. Its high content of organic materials requires biological treatment, but its sodium chloride content makes this impossible without massive dilution. Furthermore, chloride ion pollution is irreversible. Refinarias de Acucar Reunidas S.A. (R.A.R.), Oporto has developed a new process that reuses the sodium chloride solutions needed to regenerate ion exchange resins.
