Different methods are described to measure sludge sedimentation and filtration properties, by use of sedimentation indices, initial sedimentation velocity and capillary suction time.
利用沉积作用，最初的沉积作用速度和吸附时间，描述测量烂泥沉积作用和过滤产物的不同方法。

The selection offiltrationvelocity is the key of designing a fabric filter.
过滤风速的选择是设计布袋除尘器的关键。

The experiment reveals that the variation of UFE numbers is only dependent on the volume-specific deposit of filter, the effects offiltrationvelocity, bed depth and ALT ratio are not evident.
