Enhancing anaerobic digestion of automotive paint sludge through biochar addition

نویسندگان

چکیده

The reduction of traditional fuel sources and the unpredictability global economy have led to a push for renewable energy alternatives. Waste recycling can significantly reduce greenhouse gas emissions. In this study, effects different proportions biochar on efficiency mesophilic anaerobic digestion automotive paint sludge were investigated over period one month. A combination in ratio three was used, added reactor two amounts 10 26 g/l, with control sample without biochar. cumulative volume biogas produced at end one-month experiment recorded samples: (without biochar), second (with 2 g third 5.2 biochar). volumes 300, 380, 530 ml, respectively. Additionally, COD rates 25%, 33%, 48%, VS decrement 21%, 27%, 43%, findings showed that adding containing increased production. chromatography results an optimal extracted from indicated presence about 50% methane gas. These highlight potential utilizing processes improve production waste management.

Multistaged Anaerobic Sludge Digestion Processes

Two multistaged anaerobic digestion systems, a four-stage thermophilic anaerobic digestion (4TAD), all at 55°C, and a four-stage anaerobic digestion with a tapered temperature configuration (4ADT) at 55, 49, 43, and 37°C, respectively, were studied to evaluate their solids, volatile organic sulfur compounds, and indicator organism (E. coli and fecal coliform) reduction potentials. The 4TAD syst...

Improvement of Anaerobic Digestion of Sewage Sludge, Using Combined Hydrogen Peroxide and Thermal Pre-Treatment

The present study investigates the influence of individual and combined hydrogen peroxide and thermal pre-treatment of waste activated sludge on anaerobic digestion. For so doing, it employs anaerobic batch reactors in the mesophilic conditions. For comparison, soluble fractions of organic matter, biogas production, biochemical methane potential, removal of chemical oxygen demand (COD), and vol...

Anaerobic co-digestion of coffee waste and sewage sludge.

The feasibility of the anaerobic co-digestion of coffee solid waste and sewage sludge was assessed. Five different solid wastes with different chemical properties were studied in mesophilic batch assays, providing basic data on the methane production, reduction of total and volatile solids and hydrolysis rate constant. Most of the wastes had a methane yield of 0.24-0.28 m3 CH4(STP)/kg VS(initia...
