Biohydrogen Production with Different Ratios of Kitchen Waste and Inoculum in Lab Scale Batch Reactor at Moderate Temperatures
In this study, the effect of ratio of kitchen waste and inoculum like 80:20, 50:50, and 60:40 on biohydrogen production was studied. The volume of each batch reactor was 400 ml and all batch reactors were kept at 37 °C in incubator and the incubation time was 10 days. The maximum biohydrogen production was found in the 80:20 (kitchen waste: inoculum) batch reactor i. e. 13.3 % and this was on the 8th day of the start of batch reactor. The reduction in the various physical parameters in the 80:20 batch reactor was studied shows the progress in the reactors and the degradation in this reactor is high as compared to the other reactors i. e. TS-49.25 %; TDS- 68.75 %; VS-55.83 %; TSS-55.83 % and COD was 35.75 %. This study summarizes the comparative study of the biohydrogen production in the different ratios of inoculum and kitchen waste.
