Simultaneous Ammonia removal and Methane Production from Chicken Manure under Dry Thermophilic Condition
In a trail to improve and reduce the cost of dry anaerobic fermentation of chicken manure with ammonia stripping through biogas recycling, raw chicken manure (RCM) is used as a sole substrate instead of using treated chicken manure (TCM) or mixture of TCM:RCM (1:1) used previously. Biogas produced was ranged from 23.555 L kg-CM-1 with methane percentage of 70 to 85%, the amount which is 61 to 9...

متن کاملAmmonia removal from anaerobically digested dairy manure by struvite precipitation
Ammonia is one of the most important contaminants impairing the quality of water resources. When this is considered along with the fact that the global demand for nitrogenous fertilizers is in constant rise, the need for recovery as well as removal of nitrogen is well justified. Crystallization of N and P in the form of struvite (MgNH4PO4 6H2O), which is a slow releasing and valuable fertilizer...
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 کاملAmmonia Volatilization from Dairy and Poultry Manure
Ammonia volatilization is a major N loss process for surface-applied manures and urea fertilizers. The lost ammonia is important for both agricultural and non-agricultural ecosystems because it: i) is a direct loss of plant available N to the farmer, ii) reduces the N:P ratio in manure, which accelerates P build-up in soils, and iii) contributes to eutrophication in aquatic and low-N input ecos...
