Abstract | This study examined the effects of nickel on solid waste decomposition as well as its soluble concentrations duringdifferent times of addition. Three landfill reactors, loaded with 20 kg of waste, were used. Leachate recirculation was applied toall reactors, starting from Day 148. Nickel in the form of NiCl2 was added to the acid and methane reactors on Day 152 and 181,respectively. Leachate and gas parameters from all reactors exhibited similar trends during the first 151 days. Cumulative biogasproduction was356, 269, and 305 L for the control, acid, and methane reactors, respectively, indicating inhibition in the last two.Residence time of nickel in the acid reactor was more than two times that in the methane reactor (179 vs. 71 hours). Shorterresidence time of soluble nickel during the methane phase addition may be responsible for better waste decomposition and couldbe beneficial for field application. |
