Abstract

A mathematical model is developed in this paper to describe the operation of fluidized bed pellet reactor (FBPR) operating semi-continuously with liquid recycle. The reactor is designed to remove targeted ions from wastewater by reaction to form a sparingly soluble salt which precipitates on the seed pellets. The model can determine the variations of the ion concentration, the pellet size, and the voidage along the bed height during operation. In addition, it also allows one to calculate the effect of the reagent concentration and the recirculation ratio on the effluent ion concentration. A design procedure for FBPRs based on the model is also proposed.
