Abstract
The studies of fermented substrates on batch digestion and odor removal of piggery waste were carried out in laboratory scale. Several fermented products were added to batch digesters to provide additional substrates and increase the fertilized value of piggery waste. After 14 days of digestion, we can observe 50-55% removal of initial COD. Increase of fermented products resulted in the increase of initial COD in piggery waste. The addition of 10% fermented products gave the best COD removal and odor reduction ammonia comparable with digestor without addition of fermented products. H2S initially increased with the increase of fermented products and then sharply reduced to the control level for 2-3 days of experimentation.
