Abstract
A method of treating animal manure solids comprises contacting the solids with a treatment composition comprising AlCl3.nH2O or Al(NO3)3.mH2O, or the residue of AlCl3.nH2O or Al(NO3)3.mH2O, to form a treated waste product, wherein n is from 0 to 10, and m is from 0 to 12. The treatment amount can be effective to reduce phosphorus solubility in the manure; reduce phosphorus runoff and/or phosphorus leaching from fields fertilized with manure; inhibit ammonia volatilization from the manure; flocculate solids in the manure; reduce pathogens in the manure; increase the nitrogen content in the manure; and/or reduce acid rain and PM-10s associated with the manure.
Claims27
A method of treating animal manure solids comprising contacting the solids with an effective treatment amount of a treatment composition comprising AlCl3.nH2O or Al(NO3)3.mH2O, or the residue of AlCl3.nH2O or Al(NO3)3.mH2O, to form a treated waste product having an improved environmental, health and/or animal performance property, wherein n is from 0 to 10, and m is from 0 to 12.
The method of claim 25 whereby the depth of the foam that forms will be from 0.001 to 50 cm.
The method of claim 25 wherein the treatment amount is effective to reduce ammonia emissions from manure.
