Claim 0:
1. A method for treating biosolids comprising:
measuring, via one or more of in situ probes and lab analysis, one or more of pH, alkalinity, magnesium concentration, ortho-phosphorus concentration, total phosphorus content, ammonia content, total nitrogen content, total solids content, total volatile solids, polymer consumption, and metal salt consumption, each of the one or more of pH, alkalinity, magnesium concentration, ortho-phosphorus concentration, total phosphorus content, ammonia content, total nitrogen content, total solids content, total volatile solids, polymer consumption, and metal salt consumption being associated with a treatment process for wastewater solids;
determining a metal salt dosage for amending the wastewater solids based upon, at least in part, an initial ortho-phosphorus concentration and a reduction capacity to reduce a calculated Struvite Precipitation Index value to a specified level;
determining a magnesium compound dosage for amending the wastewater solids to achieve a desired condition within the wastewater solids including one or more of increasing the pH of the wastewater solids, decreasing the pH of the wastewater solids, and maintaining the pH of the wastewater solids relative to the measured pH, wherein the magnesium compound dosage is based upon, at least in part, a calculated anticipated change in the pH of the wastewater solids resulting from an addition of metal salts; and
amending the treatment process with one or more of the metal salts at the determined metal salt dosage and one or more magnesium compounds at the determined magnesium compound dosage, wherein amending the treatment process includes pumping one or more of the metal salts and the one or more magnesium compounds into one or more locations within the treatment process.
