Abstract
The fabricated fluidized bed reactor used two concentric plexiglass tubes, with diameters 5.08cm (2in) and 10.16cm (4in) and a total length of about 140cm, the reactor was designed to process about 7 liters of water in a semi-batch, recirculating operation. Commercially available dehydrated tapioca balls, with diameters 0.2cm and 0.7cm, were used as the solid phase and tested for fluidization. Comparing the results with theoretical values: for the 0.2cm particles, minimum fluidization and terminal velocities occurred at 3.33cm/s (74.80% difference) and 16.97 cm/s(22.97% difference), respectively. For 0.7cm particles, the minimum fluidization was observed at 7.9cm/s(62.15% difference) and terminal velocity was not reached (theoretically occurs at 62cm/s) due to system limitations. It was also determined that trends on particle size to liquid velocity, bed height to superficial velocity and bed porosity to superficial velocity relationships follow the expected trends for the specified system. Based on actual data, the system can sustain the required theoretical operating conditions in terms of the operating velocity ranges for 0.2cm/s and 0.7cm/s, which are 2.52-4.47cm/s and 8.96-14.95cm/s, respectively.
