Biochemical methane potential (BMP) tests have been conducted to optimize the conditions of biogas and methane production and applied to a semicontinuous operation system.
The results showed that Under the optimum conditions, the methane production increased by 46.6% in the batch tests and 120% in the semicontinuous operation system compared to the control reactor. The improved methane production originated from the synergetic effect of combining Fe0 and Mg(OH)2. Adding coated/Fe0 stimulated bacterial growth increased methane content and maintained the pH within the optimum range in the bioreactors. The dosing time of coated/Fe0 was investigated during the four stages of the anaerobic digestion process, and the best dosing time was found in the methanogenic stage (on Day 4). Overall, based on the experimental and predicted methane production, the coated/Fe0 has great potential for the practical applications of anaerobic digestion. moreover, the investigation also extended to evaluate the co-digestion by using aloe vera biomass The main Achievements have been published in Renewable and Sustainable Energy Reviews with an impact factor of 15.9 under the title A novel method to improve methane generation from waste sludge using iron nanoparticles coated with magnesium hydroxide. Currently, the second paper under the title Exceptional contribution of iron nanoparticle and Aloe vera biomass additives to biogas production from anaerobic digestion of waste sludge has been accepted by Energy with an impact factor of 9.0
