Última RESPONSE FROM ANAEROBIC DIGESTION OF LAYING HEN MANURE WITH BIOCHAR ADDITION 70 Andrade,Willian R.; Ferreira,Cecilia de F. S.; Gates,Richard S.; Borges,Alisson C.; Santos,Tânia M. B. dos. ABSTRACT This study aimed to assess the anaerobic digestion response of laying hen manure with different inclusion levels of biochar in batch reactors as measured by physicochemical parameters, biogas production and digestate quality. Four levels of biochar inclusions (0, 2.5, 5.0 and 7.5%) were tested with 3 replicates each. Twelve two-liter anaerobic batch reactors were used for 86 days at 35°C. Substrate and digestate of each treatment were assessed for monitored parameters, biogas production and digestate quality. Increased levels (0, 2.5, 5.0 and 7.5%) of biochar were found to gradually reduce total ammonia nitrogen (1794.33, 140.84, 950.81 and 509.32 mg.L-1, respectively). Despite the positive effect of biochar to accelerate initial biogas... Tipo: Info:eu-repo/semantics/article Palavras-chave: Biogas yield; Total ammonia nitrogen; Volatile solids.

The exploitation of plant materials for renewable source of energy in form of biogas is of growing interest. Water leaf (Talinum triangulare), an abundantly available underutilized herbaceous perennial plant in South-Western Nigeria was digested to assess its biogas yield. Water leaf (WL) and Water hyacinth (Eichhornia crassipes) alone, and mixtures of water hyacinth (WH) and WL at ratios 70:30, 50:50 and 30:70 (w:w dry basis) were digested to compare biogas yields. Fixed amount of cow dung was added to each treatment before digestion in batch-type anaerobic digesters for 70 days. The results of the study showed that feedstock mixture affected (p ≤ 0.05) pH and biogas yield. WL proved to be prolific in biogas as it yielded approximately six times greater...

Ano: 2015 URL: http://www.cigrjournal.org/index.php/Ejounral/article/view/2841 Effect of digester surface area on biogas yield 111 Ogunwande, Gbolabo Abidemi. Poultry manure, cow dung and swine manure were digested in cube-shaped anaerobic digesters of equal volume but different surface areas (SAs) (5.38, 10.0 and 11.6 dm2) in a two-factor experiment. The digesters were agitated once a day during the experiment. The results showed that neither the manure type nor SA affected (p > 0.05) substrate temperature and pH, but both had (p ≤ 0.05) on biogas yield (BY. Poultry manure had the highest BY followed by swine manure and cow dung (1.00, 0.59 and 0.11 dm3 kg-1 VS fed day-1, respectively). Within the SAs investigated, BY increased as digester SA increased (0.27, 0.68 and 0.74 dm3 kg-1 VS fed day-1 for 5.38, 10.0 and 11.6 dm2, respectively). The results of the regression analysis showed that digester diameter to...
