Alternativa para el tratamiento de salmueras del procesado de la aceitunas: procesos químicos y biológicos

[EN] The treatment of fermentation brine from Spanish style green table olives processing is difficult by to their very nature. These wastewaters are characterized by very high conductivity (77-99 mS/cm), high values of suspended solids (700-1.900 mg/L) and chemical oxygen demand -COD- (13.800-22.00...

Sumario:[EN] The treatment of fermentation brine from Spanish style green table olives processing is difficult by to their very nature. These wastewaters are characterized by very high conductivity (77-99 mS/cm), high values of suspended solids (700-1.900 mg/L) and chemical oxygen demand -COD- (13.800-22.000 mg/L). Furthermore, these waters containing phenolic compounds (800-1.300 mg/L). In this work, fermentation brines have been exhaustively characterized, by analysing 20 samples from a packaging plant. Also, have been evaluated the alternatives below for their treatment: pH adjustment with sedimentation, adsorption and biological treatment.
