Application of halloysite sorbent for ammonia and odors removal from dry toilet facilities
Halloysite sorbent was added to liquid urine (dose 10 g/dm) and solid faeces (unmodified structure, dose 50 g/kg) being a subject of anaerobic fermentation in a hermetic system for 20 days. Identification of surface morphology and elementary chemical composition in microregions of the spent sorbent were done using scanning electron microscope Zeiss Supra 35 equipped with EDS detectors. Both gra...
متن کاملAmmonia Volatilization from Urea-Application Influenced Germination and Early Seedling Growth of Dry Direct-Seeded Rice
Poor seed germination and early seedling growth associated with urea-induced soil ammonia volatilization are major constraints in the adoption of dry direct-seeded rice. To directly examine soil ammonia volatilization and its damage to seed germination and early seedling growth of dry direct-seeded rice when urea is applied at seeding, two Petri-dish incubation experiments and a field experimen...
متن کاملModeling studies of ammonia dispersion and dry deposition at some hog farms in North Carolina.
A modeling study was conducted on dispersion and dry deposition of ammonia taking one hog farm as a unit. The ammonia emissions used in this study were measured under our OPEN (Odor, Pathogens, and Emissions of Nitrogen) project over a waste lagoon and from hog barns. Meteorological data were also collected at the farm site. The actual layout of barns and lagoons on the farms was used to simula...
متن کاملAmmonia removal using activated carbons: effect of the surface chemistry in dry and moist conditions.
The effect of surface chemistry (nature and amount of oxygen groups) in the removal of ammonia was studied using a modified resin-based activated carbon. NH(3) breakthrough column experiments show that the modification of the original activated carbon with nitric acid, that is, the incorporation of oxygen surface groups, highly improves the adsorption behavior at room temperature. Apparently, t...
متن کاملSimultaneous 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...
