瓶装矿泉水沉淀原因及解决方法

探讨了导致瓶装饮用天然矿泉水产生沉淀的主要原因及其解决方法。研究表明：沉淀主要由Ca2+、Mg2+及Fe3+组成；高温、低温、振动及中性条件均加速沉淀的形成；采用CaO处理，结合曝气，经过粗滤、除铁锰处理、微滤、超滤、O3消毒、0.01μm终端过滤工艺，可有效防止沉淀形成。

The removing method and main reason for precipitation of natural mineral water was studied. The results showed that precipitation are Ca(2+)、Mg(2+) and Fe(3+) .Precipitation quicken when high temperature, low temperature, vibration and pH7.and can be avoided by treatment with CaO mixing air removing Fe(2+) and Mn(2+).
