    • 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.
    • 描述了利用用于废水处理和中和的铝,镁和钙基添加剂的方法和组合物,用于从废水中除去污染物,包括还原含磷化合物,总悬浮固体(TSS),生物需氧量(BOD),脂肪 ,油和油脂(FOG)和总克耳希尔氮(TKN)。 描述了控制废水和可沉淀固体中存在的pH,硫和钠负荷的方法和组合物。 铝,镁和钙基添加剂的浓度保持在废水中存在的废水组分水平的质量作用浓度,并且围绕可溶性缓冲物质的pK值约占+/- 0.5个pH单位。
