The addition of a deliquescent salt, such as calcium chloride, to alum to treat animal waste products rapidly activates the alum to remove ammonia from the atmosphere. The ammonia sulfate by-product is useful as a nitrogen fertilizer.Field of SearchDEODORANTS (NONBODY)For application to waste materials, solid or liquid refuse or sewage Waste includes fecal material or urine (e.g., feed lot or cage waste, pet litter, etc.) INORGANIC ACTIVE INGREDIENT CONTAINING Aluminum, calcium or magnesium element, or compound containing Alum or burnt alum MATERIAL FOR ABSORBING MOISTURE FROM WASTE PRODUCT | |
