In general, a method for treating biosolids may include measuring 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 associated with a treatment process for wastewater solids. A metal salt dosage for amending the wastewater solids may be determined based upon, at least in part, an initial ortho-phosphorus concentration and a reduction capacity of the metal salt. A magnesium compound dosage may be determined for one or more of increasing, decreasing, and maintaining a pH of the wastewater solids. The magnesium compound dosage may be based upon, at least in part, a calculated anticipated change in pH of the wastewater solids resulting from an addition of the metal salts. The method may also include amending the treatment process with the determined metal salt dosage and the determined magnesium compound dosage.

Despite the excellent properties associated with Magnesium OxyChloride (Sorel) based cements and Magnesium OxySulfate based cements, water and corrosion resistance has been limiting factors for achieving greater commercial applications. Such issues can be addressed by incorporating various alkali metal phosphates, such as Magnesium mono- or dihydrogen phosphate (MgHPO4 or MgH2PO4) with alkali metal fatty acids; such as Magnesium Stearate; and metal or alkali metal sulfates such as Aluminum Sulfate or Magnesium Sulfate. Water resistance is further enhanced by either pre-carbonating the mix water or the liquid magnesium chloride phase of the cements, or by adding a carbonate into the powder phase. Accelerated cure of this system has also been obtained by using various inorganic metal oxides. Additionally, improved corrosion resistance is achieved through the use of certain phosphates, zeolites, nitrites and other novel additives.

Portland Cement-based concretes and mortars exhibit significant reduction in shrinkage cracking when combined with Magnesium Oxide (MgO), Shrinkage Reduction Admixtures (SRA) and Super Absorbent Polymers (SAP). However, MgO is a solid that reacts with water, SRA is a liquid, and SAP if not added properly could pull water out of the system and thus increase shrinkage. Unique admixture blends used as supplementary cementing materials that do not significantly affect concrete or cement strength properties of Portland cement itself address such issues. Proper ratios of MgO, SRA and/or SAP perform better against crack reduction when compared to commonly used Expansive Cements (EC).
