5.2 Suggestions
1. Finding the optimal conditions for acidogenic stage operation including OLR, HRT, mixing
intensity and maintain process under low hydrogen partial pressure condition.
2. Finding the optimal conditions for methanogenic stage operation including biomass
concentration, OLR, HRT, re-circulating flow rate and maintain process under low hydrogen
partial pressure condition.
3. Monitoring of H 2S gas produced in both H 2-CSTR and CH 4-UASB reactors as well as
microbial community analysis to derive the relationships of their.
4. Identification of sugars composition contained in both skim latex serum and palm oil mill
effluent to classify metabolic pathway will be incurred through anaerobic dark co-digestion of
SLS and POME by thermophilic mixed cultures.
