Zeolite NaX Mass and Propeller Agitator Speed Impact on Copper Ions Sorption

Sorption is often carried out in stirred batch reactors without any consideration of how much mixing sufficient to avoid the effect diffusion compromising yield and cost due overmixing. Therefore, focus this work was study maximum sorption capacity, removal efficiency, kinetics power consumption (P) studied process are affected by different speeds, i.e., impeller speed/minimum speed for complete suspension (N/NJS) ratio values zeolite mass concentrations. Experiments were conducted a baffled reactor with propeller at standard off-bottom clearance. In addition experimental studies, numerical modelling approaches investigate using transient multiphase computational fluid dynamics model fitting selected kinetic models. The results show that an increase leads slight NJS consequently PJS. affects velocities, consumption, kinetics, final amount efficiency copper sorbed. experimentally determined data fit Ritchie’s well. However, two experiments, performed N/NJS ratios 0.8 0.6, Mixed fits better, suggesting second-order reaction suppressed diffusion. Due influence diffusion, decreased from 59.377% 54.486% 46.372% respectively.
