| Abstract: | Background, aim, and scope Alum (aluminum sulfate) is the currently preferred chemical amendment for phosphorus (P) treatment in poultry litter (PL).
Aluminum-based drinking-water treatment residuals (Al-WTRs) are the waste by-product of the drinking-water treatment process
and have been effectively used to remove P from aqueous solutions, but their effectiveness in PL water extracts has not been
studied in detail. Elevated cost associated with alum could be minimized by using the equally effective WTRs to remove soluble
P from PL, and they can be obtained at a minimal cost from drinking-water treatment plants. |
