A study on thickening waste activated sludge was carried out in a pilot-scale dissolved-air flotationunit. Thickening process curves in different operational parameters were obtained.
通过中型试验研究，获得了在不同运行参数情况下的活性污泥气浮浓缩过程曲线；

An inflatable PFD has less bulk and interference than a foam unit, but is ready to provide flotation during an unexpected entry into the water.
可膨胀的PFD有较少的体积和没有了干扰泡沫单位，但在想不到的进入水后实时提供漂浮。
