The experimental result indicated that lime could enhance the water flow rate of wastewater in the pelleting fluidized bed ( PFB), and save polyacrylamide ( PAM) dosage.

It has been reported that PFB can improve the properties of flow, heat and mass transfer in fluidized bed. However, the complex bed behavior is more difficult to study.

气固脉动流化床是在普通流化床的基础上加入脉动气流，文献中报道了其可以改善普通流化床的流动及传质传热特性，但流化床内更为复杂的流动状态，使得研究变得更加困难。
