大量饮用水公用事业公司在混凝添加点附近使用硫酸铝（明矾）进行常规水处理。本研究旨在评估氟化物对明矾常规饮用水处理的影响。采用了小型罐试验、中试研究和化学平衡建模。数据显示，氟化物的存在会对沉淀水的质量产生负面影响（即颗粒数、浊度和残余铝含量增加）。 氟的影响是pH值和明矾浓度的函数。包括12个参考文献、表格和图表。

A significant number of drinking water utilities that practice conventional watertreatment using aluminum sulfate (alum), fluoridate near the point of coagulationaddition. A study was conducted to evaluate the effect of fluoride onconventional drinking water treatment using alum. Bench-scale jar test,pilot-scale studies, and chemical equilibrium modeling were used. Data showedthat the presence of fluoride can negatively affect settled water quality (i.e.,increased particle counts, turbidity, and residual aluminum levels). The impactof fluoride was a function of pH and alum concentrations. Includes 12 references, tables, figures.
