ABSTRACT
The first step in the physicochemical optimization process is to define specific performance criteria as well as indicators—characteristic parameters of flocculation efficiency. The agglomeration process was randomly optimized for a number of process variables and reference points using quasi-factorial experimental design to select the optimization points. The optimization of the micro processes that influences the pre-treatment technique was performed in the flow devices with different geometries. The results of agglomeration and gravity dewatering experiments and the corresponding optimum process conditions for the pelleting process are described. The effect of the micro-processes on the subsequent phase separation efficiency by simple gravity dewatering was investigated by determining the dry solids content of the dewatered pellets. The aim of the physicochemical optimization is to select the appropriate flocculant and dosage or range of dosage. The physicochemical optimization has been successfully employed for effective polymer dose prediction for the pelleting process.
