The higher the sludge concentration and the flux were, the easier it was for the sludgeparticles to deposit on the membrane surface.
污泥浓度愈高，膜通量愈大时，活性污泥颗粒愈易在膜面沉积。

In the wastewater conditioning and concentration process, lime can be used to raise density of the sludgeparticles, and improve the property of sludge dewatering.
石灰作为一种传统的助凝剂，应用于水厂排泥水调质浓缩工艺，可提高污泥颗粒密度，改善污泥沉降脱水性能。
