Pretreatment with the addition of metals to anaerobic digestion in biogas production is crucial address improper degradation organic compounds low methane production. Biogas from a combination cassava pulp and wastewater batch system under variation alkaline heat conditions as pretreatment was investigated zero-valent iron (ZVI) after pretreatment. It found that at pH 10 100 °C for 30 min combi...
Carbon emission is one of the main causes global climate change, thus it necessary to choose a low-carbon method in contaminated soil remediation. This paper studies adsorption ability ZVI on Pb(II) soils under different working conditions. The removal efficiency was 98% because suitable dosage, log reaction time and low initial solution concentration. whole balancing process much fast accordin...
Large amounts of NH3 and H2S are emitted during sewage sludge composting, resulting in odor pollution. This composting experiment was carried out using mixed with sawdust, different zero-valent iron (ZVI) were added to investigate the effect on volatile gases, such as H2S, analyze available sulfur, total moisture content, germination index compost. The results showed that addition ZVI process h...
A new kind of micro-electrolysis filler sewage sludge biochar/zero valent iron (SSBC/ZVI) composite was prepared for a real chemical synthesis based pharmaceutical wastewater pretreatment improving the biodegradation index (BI). The optimal operation condition system obtained at HRT 2 h, initial pH 3.0 and dosage 100 g/L, with COD removal rate 30.5%. Characterization analysis raw/used SSBC/ZVI ...
Abstract Zvi Griliches was one of the leading econometricians his generation. His early work involved empirical analyses sources productivity growth in twentieth-century US agriculture, including dissertation on diffusion hybrid corn and analysis long-run fertilizer use by farmers. In this research developed theoretical explanations these phenomena form narratives rational, profit-seeking peopl...
Pretreatments of pH and heat with zero-valent iron (ZVI) additions enhance anaerobic digestion increase reducing sugar availability for optimum biogas production. This study aimed to optimize the conditions different pretreatment additional ZVI yield higher amounts from (AD) cassava wastewater. Thirteen conditions, ten concentrations, eleven heating periods were varied measured standard conditi...
Iron-based amorphous crystalline powder Fe78Si9B13AP is used as a permeability reaction barrier (PRB) combined with an electrokinetic method (EK-PRB) to study the removal rate of Cu in contaminated soil. After treating Cucontaminated soil for 5 days under different voltage gradients and water content, pH between 3.1 7.2. The increase gradient content ...
