Presentation Transcript

  1. Pharmaceutical Effluent Treatment Using Sequencing Batch Reactor • Effluent from pharmaceutical industry contains disintegrated form of the drugs - high chemical oxygen demand (COD), volatile solids and organic solvent. • Reducing COD, TDS and ammonia using Sequencing Batch Reactor • Activated sludge unsteady state process • All unit operations – aeration, nitrification, denitrification, settling & decanting in one reactor • Performance estimation by COD, DO, pH and total solids measurement • Previous studies on SBR – • municipal waste - Umble & Ketchum (1997) • slaughter house waste - Masse & Masse (2001) • food and dairy - Torrijos et al (2001) • landfill leachate - Neczaj et al., 2005

  2. About 81 % COD removal in 24 hour run and 90% removal in 48 hour operation • Better solids removal or sludge settling was observed in the anaerobic phase. • Suspended solids concentration increase in aerobic phase. • This may be due to microbial growth or resuspension due to aeration.
