Evaluation on applying Condensate from Food Waste Dry Process as External Carbon Source to Biological Denitrification Process

Objectives:In this study, the applicability of dry condensate generated from food waste feed conversion process was evaluated as an external carbon source to increase efficiency biological denitrification process.Methods:The experiment carried out in form a batch test, and injected into each reactor according COD T/N ratio (C/N ratio). Then, operated under anoxic conditions for 5 hours, nitrate nitrogen analyzed at intervals 1 hour.Results Discussion:The showed low content (T-N 220 mg/L) compared high organic matter (TCOD 21,863 mg/L), satisfy process. And result experiment, it found that removal up 76% after hours C/N 7.50:1, which significantly increased control without condensed water (removal 4%). Moreover, 28% exhibited even 0.95:1, lowest efficiency. In addition, calculating specific rate (SDNR) ratio, 7.50:1 be 0.0726 mg NO3-/mg VSS/d, than 0.0038mg VSS/d.Conclusion:Based on these results, is judged possible utilize dried
