ANAEROBIC CO-DIGESTION OF SWINE AND LAYING HEN WASTE FOR BIOGAS GENERATION AND DIGESTATE QUALITY
نویسندگان
چکیده
Anaerobic digestion (AD) stands out as a degradation pathway for the treatment of agro-industrial waste. This study aimed to evaluate biogas production (Pb) from co-digestion swine (SW) and laying hen waste (LHW) under different temperature conditions (psychrophilic x mesophilic). The studies were carried on laboratory scale in anaerobic reactors (1.25 L) batch system 60 days. Three mixtures volumetric proportions (%) 25/75 (P1), 50/50 (P2), 75/25 (P3) (SW/LHW) studied. characterized before after AD terms TS, VS, COD temperatures 18 36 °C, with Pb measured daily. was higher at °C all compared psychrophilic condition (18 °C). Among mixtures, highest value observed P3, reaching 0.34 0.60 m3 kg−1 CODremoved respectively. digestate showed an increase contents micro-and macronutrients P1, P2, P3 AD, which indicates its use agricultural purposes. is promising proposal management energy recovery biogas, especially mesophilic predominance

متن کاملAnaerobic 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...

Swine wastewater (SW) and olive mill wastewater (OMW) are two problematic wastes that have become major causes of health and environmental concerns. The main objective of the current work was to evaluate the efficiency of the co-digestion strategy for treatment of SW and OMW mixtures. Mesophilic batch reactors fed with mixtures of SW and OMW showed that the two adapted sludges Gadot and Prigat ...

This research was aimed at assessing the fertilizer quality and public health implications of using digestate biofertilizer from the anaerobic digestion of food wastes and human excreta. Twelve (12) kg of food wastes and 3kg of human excreta were mixed with water in a 1:1 w/v to make 30-l slurry that was fed into the anaerobic digester to ferment for 60days at mesophilic temperature (22-31°C). ...
