Enhancement of biogas production from bio-sludge and batch experiment for biogas potential set-up

บทคัดย่อ

Anaerobic digestion is an efficient waste treatment and generates biogas. The producing biogas can be used for electricity and heat a generator. Biogas obtained from bio-sludge is an attempt to achieve the waste gain and minimization. The enhancement of biogas production from bio-sludge can be achieved by conducting of a treatment stage before or after anaerobic digestion. Thermal-alkaline condition at 170 C with pH 10 used ํ as a pre-treatment provided an improvement of 54% of biogas production while, athermal microwave showed an increase in 16% of biogas production. The important aspects to create a batch experiment on biogas potential from the waste include the homogeneity and analysis of the waste composition, which consists of total solids, volatile solids, total kjeldahl nitrogen, ammonium, lipids, COD, and pH. Volatile fatty acids evolution is recommended to monitor during the batch experiment for investigating the relation or inhibition effect on biogas production especially during the start-up period of the experiment. Nevertheless, considering of statistical and experimental control is also recommended for accuracy and reliability of the obtained results Read the rest of this entry »
