A kinetic model based on electrochemical principles, elementary reactions and phase equilibrium was constructed to describe electrocoagulation. The approach was successfully illustrated for the removal of phosphate ions and other pollutant parameters from a brewery effluent. The kinetic results were obtained from a factorial design of experiments at optimal conditions for removal of phosphate and COD. Al³⁺ from the electrolysis of zero-valent aluminum reacted with phosphate at a rate constant of ~8.16 × 10⁷ L mol⁻¹ s⁻¹ to form aluminum phosphate. Hexose sugars adsorbed on aluminum phosphate at a rate constant of ~5.34 × 10² L mol⁻¹ s⁻¹ were removed by flotation at the same rate of COD. The concentration of soluble aluminum was dependent on multiple reactions involving aluminum species and on the equilibrium between soluble and solid aluminum species. Turbidity was associated with the formation of aluminum phosphate and its removal by flotation at a rate constant of ~1.49 × 10⁻³ s⁻¹.

建立了基于电化学原理，基本反应和相平衡的动力学模型来描述电凝。该方法已成功地说明了从啤酒废水中去除磷酸根离子和其他污染物参数的方法。动力学结果是从因子设计实验中获得的，该条件是在最佳条件下去除磷酸盐和COD的。来自零价铝电解的Al ³⁺与磷酸盐以〜8.16×10 ⁷ L mol ^-1 s ^-1的速率常数反应形成磷酸铝。己糖以〜5.34×10 ² L mol ^-1 s ^-1的速率常数吸附在磷酸铝上通过浮选以相同的COD速率除去。可溶性铝的浓度取决于涉及铝物质的多个反应以及可溶性和固态铝物质之间的平衡。浊度与磷酸铝的形成以及通过浮选以约1.49×10 ^-3 s ^-1的速率浮选有关。
