Adsorption characteristics and mechanism of ammonia nitrogen and phosphate from biogas slurry by Ca2+-modified soybean straw biochar. [PDF]

PLoS One, 2023
The utilization of biogas slurry is critical for the sustainable development of animal husbandry. Biomass carbon adsorption is a feasible method for the recycling of nutrients from biogas slurry. However, research on the co-adsorption of ammonia nitrogen

Biogas Slurry Logistics Assessment: Tanker vs. Umbilical System

, 2011
The continuous development of new crops for anaerobic digestion has led to the need to manage in a rational and environmental­friendly way the distribution of the digested products that comes out of the biogas plant. The EU, national, and regional regulations set the time windows when it is allowed to carry out the slurry applications and the limits on

Cow Urine for Enhancement of Biogas Production and Fertilizer Quality of Biogas Slurry

Journal of Scientific Research, 2020
To explore the potency of cow urine on biogas production and fertilizer quality of the biogas slurries, six experimental trials,  T0 (50% CD:50% Water) as control, T1 (10% CD:90% CU), T2 (20% CD:80% CU), T3 (30% CD:70% CU), T4 (40% CD:60% CU) and T5 (50% CD:50% CU) were constructed  by mixing cow dung (CD) and cow urine (CU).

Long-term temperature measurement: Biogas digesters fermenting slurry

Journal of Energy in Southern Africa, 2017
This paper reports the results of the temperature profile of the unheated and unstirred continuous fermenting bio-slurry in a fixed-dome Deenbandhu 2000 model. The digester is a brick-built system of bulk size 6 m3. The digester was monitored for eight months, measuring internal bio-slurry temperature. A K-type nickel chromium-nickel temperature sensor

Environmental risks in swine biogas slurry-irrigated soils: A comprehensive analysis of antibiotic residues, resistome, and bacterial pathogens

Environment International
Simple anaerobic digestion is insufficient to completely remove residual parent antibiotics and antibiotic resistance genes (ARGs) from animal manure. ARG prevalence in swine biogas slurry-irrigated soils threatens human health.
