摘要: A model is developed that describes the charge neutralization aspects of coagulation, based on fundamental equations describing aluminum speciation and solubility, particle electrodouble‐layer characteristics, and the effect of aluminum‐hydroxide deposition on the surfaces of colloidal or suspended particles. Model predictions are compared with results from closely controlled jar‐test experiments employing the addition of aluminum salts to synthetic suspensions, with good agreement under most conditions. The model's success …
