由于水中含有悬浮及胶体状态的微粒，使得原来无色透明的水产生浑浊现象，其浑浊的程度称为浑浊度。浑浊度的单位是用"度"来表示的，就是相当于1L的水中含有1mg.的SiO2（或是非曲直mg白陶土、硅藻土）时，所产生的浑浊程度为1度，或称杰克逊。浊度单位为JTU，1JTU=1mg/L的白陶土悬浮体。现代仪器显示的浊度是散射浊度单位NTU，也称TU。１TU＝１JTU。近，国际上认为，以乌洛托品－硫酸肼配制浊度标准重现性较好，选作各国统一标准FTU。１FTU＝１JTU。浑浊度是一种光学效应，是光线透过水层时受到阻碍的程度表示水层对于光线散射和吸收的能力。

它不仅与悬浮物的含量有关，而且还与水中杂质的成分、颗粒大小、形状及其表面的反射性能有关。控制浑浊度是工业水处理的一个重要内容，也是一项重要的水质指标。根据水的不同用途，对浑浊度有不同的要求，生活饮用水的浑浊度不得超过５度；要求循环冷却水处理的补充水浑浊度在２～５度；除盐水处理的进水（原水）浑浊度应小于３度；制造人造纤维要求水的浑浊度低于0.3度。由于构成浑浊度的悬浮及胶体微粒一般是稳定的，并大都带有负电荷，所以不进行化学处理就不会沉降。在工业水处理中，主要是采用混凝、澄清和过滤的方法来降低水的浑浊度。
