The present investigation is the recovery of highly toxic heavy metals of chromium from waste effluents using beads Spirulina platensis. The effluent has been subjected to batch operation of Liquid solid Fluidized bed reactors (LSFB) with varied concentrations of stock solutions, time, pH, and pressure drop for bio-treatment studies. LSFB processes using dead Spirulina platensis beads followed by characterization of UV screened toxic chromium ions are recovered for the time interval of 120 minutes at constant 5 pH. The results indicated that the high recovery of chromium ions with hydrodynamic constraints of high efficiency of 82.3% at 150 LPH is recorded. Thus, the sustainable and eco-friendly way for the removal of toxic chromium ions is also examined under the linear isotherm model of the BET, Langmuir and Freundlich isotherm models. The best fit is BET Isotherm as compared with Langmuir and Freundlich isotherm model with maximum efficiency in recovery chromium ions of experimental value of B (Constant) of 1.346×10 was also reported.
