Abstract

In this study, we investigated Terasil blue dye absorption on modified rice husk through batch and continuous trials. In continuous mode includes experimental tests in an inverse fluidized bed teqnique at various times and under various operating conditions (bed height, initial concentration, and varying flow rate) were investigated. The effect of various factors like pH, contact time, agitation speed and particle size on the removal efficiency (%) the Terasil blue dye were thoroughly investigated. The maximum removal efficiency (%) was achieved up to pH 7.0. Removal efficiency (%) increased with increasing contact time. The maximum removal efficiency (%) was achieved @200 RPM (rate per minute). Increasing in the particle size caused decreased in the removal efficiency (%). In batch experiments the Freundlich, and Temkin models showed good agreement with R2 value while the Langmuir model had moderate agreement. The value of qe is 1.73 mg/g under specific conditions; the Langmuir model provides q-max of 0.0078 mg/g and K-L of 0.0801 L/mg.Ongoing tests conducted in an inverse fluidized bed offer valuable insights into the hydrodynamic behavior of the system.

 

The collected data effectively demonstrates the variations in pressure drops and bed heights. There is a positive correlation between bed height and fluid velocity, suggesting a significant association within the dynamics of fluidized beds.
