Abstract
A two-stage aerobic Sequencing Batch Reactor system (SBR) designed and constructed by INCD-ECOIND’s
specialists was used for treatment of the wastewater discharged from drugs fabrication (conditioning
operations), with variable concentrations of organic load: COD = 1200-3300 mg O2/L, BOD5 = 490-1570 mg
O2/L. After acclimation period, the 1st stage and 2nd stage SBRs were able to achieve COD and BOD removal, with global efficiencies ranging from 63-97% and 82-99% respectively (HRT = 9 h). The effluent quality is in compliance with the discharge standards (GD352/05 - NTPA002). The paper also presents laboratory-scale experimentation carried out for the processing of excess biological sludge (stabilization / conditioning, leaching tests) in order to find out its subsequent destination
