| dc.description.abstract | he efficiency of banana winery effluent (BWE) in biogas production through improving fermentation process
was investigated in this study. The study was conducted in a batch system under mesophilic temperature of 35oC achieved by
using controlled thermostat waterbath. Two sets of experiments (labeled as experiment 1 and experiment 2) with five reactors
each, were performed in the laboratory. For experiment 1, reactor A was treated as a control with no addition of urea while
1g,2g,3g and 4g of urea were added in reactors B,C,D and E respectively. For experiment 2, different amount of sucrose, that
is 0.18g, 0.27g, 0.36g and 0.44g were added in the reactors B, C, D and E correspondingly, and reactor A without sucrose
addition was used as the control .Results for experiment 1 revealed that reactor A produced largest volume of biogas (1.93L)
followed by reactor B with least amount of urea where 1.37L of biogas was generated. Other reactors produced smaller
volume of biogas during the study period. For experiment 2 results indicated large volume of biogas (2.72L) was produced in
reactor C with 0.27g of sucrose followed by reactor D (2.71L) with 0.36g sucrose. The biogas produced contained 68.9% -
74.6% methane (CH4). This study concluded that addition of nitrogen source does not increase biogas production from
Banana winery effluent while addition of carbon source is important as a source of energy for enhancing C: N ratio for
process stability and biogas production. | en_US |
