Modelling Anaerobic Digestion of Cow Manure to Predict Methane Flow Rate
Anaerobic digestion (AD) of biowastes is one of the most common ways to produce methane-rich biogas, which has considerable potential to replace the fossil fuel used in multiple applications, such as vehicular transportation, internal combustion engines, cogeneration of heat and power systems and many other systems. Many companies are involved in the design and construction of anaerobic digesti...
متن کاملAnaerobic Digestion of Flushed Dairy Manure
In Florida, dairies use water extensively for barn flushing and waste collection, because it is sanitary and less labor-intensive. However, the practice of hydraulic flushing results in greatly increased volumes of dilute wastewater. In addition, many dairies have incorporated fan and sprinkler cooling systems for cow comfort in the warm Florida climate, which contributes even more water to the...
متن کاملMesophilic digestion kinetics of manure slurry.
Anaerobic digestion kinetics study of cow manure was performed at 35 degrees C in bench-scale gas-lift digesters (3.78 l working volume) at eight different volatile solids (VS) loading rates in the range of 1.11-5.87 g l-1 day-1. The digesters produced methane at the rates of 0.44-1.18 l l-1 day-1, and the methane content of the biogas was found to increase with longer hydraulic retention time ...
متن کاملAnaerobic digestion of dairy manure with enhanced ammonia removal.
Poor ammonia-nitrogen removal in methanogenic anaerobic reactors digesting animal manure has been reported as an important disadvantage of anaerobic digestion (AD) in several studies. Development of anaerobic processes that are capable of producing reduced ammonia-nitrogen levels in their effluent is one of the areas where further research must be pursued if AD technology is to be made more eff...
متن کاملAnaerobic digestion of cattle manure: effect of phase-separation
Various aspects of anaerobic digestion (AD) technology have been the focus of research in recent years. Shortening the digestion time with enhanced process efficiency is one of the integral concerns in AD technology. This study was conducted to investigate the feasibility of a two-phase anaerobic treatment system for unscreened dairy manure. Hydraulic retention time (HRT) and organic loading ra...
