Abstract: Compositions, systems, and methods of using alkaline-producing Aluminate salts in the sludge collection and digestion steps of wastewater processing to reduce acidity and/or build alkalinity, reduce hydrogen sulfide release, and reduce phosphate in the effluent.

Abstract: Embodiments described include methods for maintaining the pH and alkalinity during industrial fermentation processes are described that foster optimal microorganism activities throughout the duration of the fermentation process. Magnesium based buffering agents having sufficient buffering capacity and applied at sufficient concentration levels required to neutralize the acidic content of fermentation fluids during the fermentation process cycle are detailed. These magnesium based buffering agents control fermenter processes without causing extreme pH swings to maximize the production of desired fermentation products.

Abstract: Methods and compositions utilizing aluminum, magnesium, and calcium-based additives for the treatment and neutralization of wastewater are described for removing contaminants from wastewater, including reducing phosphorous-containing compounds, total suspended solids (TSS), biological oxygen demand (BOD), fats, oils, and greases (FOG), and total Kjedahl nitrogen (TKN) are described. Methods and compositions to control pH, sulfur and sodium loads present in wastewater and precipitatable solids are described. Concentrations of aluminum, magnesium, and calcium-based additives are maintained at mass action concentrations to the wastewater component levels present in the wastewater and bracketed approximately +/?0.5 pH units about the pK value of the soluble, buffering species.
