Abstract: Process for producing a rapidly-soluble, structurally-strong, storage-stable chlorine releasing tablet by compressing sodium dichloroisocyanurate dihydrate in a structure-forming apparatus with pressures from about 2,000 to about 10,000 p.s.i.

Abstract: Controlling the odor of an animal waste slurry and increasing the plant nutrient values in said animal waste slurry is achieved by contacting an animal waste slurry with about 5 ppm to about 500 ppm hydrogen peroxide, adjusting the pH of the slurry to between about 4.0 and about 8.0 with a mineral acid, mixing the slurry until the odor is no longer objectionable, and recovering the animal waste slurry which contains increased amounts of ammonium salt values.

Abstract: Solid peroxygens may be compressed into shaped forms with or without additives to regulate the dissolving rate of the forms. Use of such peroxygen forms provides a simple and inexpensive method to dispense active oxygen and an alkali into a solution over a predetermined time to oxidize sulfides to sulfates and thus to reduce the chemical oxygen demand. Sodium carbonate peroxide and sodium perborate are two commercial peroxygen compounds particularly useful for this application as they provide both the active oxygen to oxidize the sulfide, and the alkalinity required to raise the pH of the solution to pH 8 or greater, thus preventing the formation of elemental sulfur. In addition, the two compounds are compatible with additives, such as carboxymethylcellulose and methylcellulose, which are useful in regulating the dissolution rate, as well as soda ash, which can be used to provide additional alkalinity.
