Deliquescent salt addition to alum used to treat animal waste products

摘要

Animal enclosures such as poultry houses generate high amounts of ammonia that adversely affect weight gain and mortality or the animals, particularly among young chicks. 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.
