Biodegradability and methane productivity during anaerobic co-digestion of refractory leachate

  title={Biodegradability and methane productivity during anaerobic co-digestion of refractory leachate},
  author={Minako Kawai and Michiko Kishi and M. Robert Hamersley and Norio Nagao and Joni Hermana and Tatsuki Toda},
Mature landfill leachate was anaerobically co-digested with synthetic wastewater to evaluate the degradability and methane productivity in various mixing ratios. The proportion of leachate was increased in three equal steps from 0% to 100%, and then decreased again through the same steps back to 0%. Both COD removal efficiency and methane production decreased as the leachate proportion in the influent was increased. When the influent contained 100% leachate, and when 33% synthetic wastewater… CONTINUE READING
