T lant Blue R BBR dyestuff, which is a textile dyestuff, by biosorption is investigated. For this purpose, eggshell immobilized with chitosan ESIC is designed as a biosorbent. The biosorption mechanism was studied in batch and continuous mode. As far as the batch system is concerned, the following results have been obtained: The optimum pH 2, dye concentration 25 ppm, interaction time 60 minutes, biosorbent amount 2.0 g/L, removal real wastewater 53.28%. Regarding continuous systems, the following flow speed of 0.5 mL/min, biosorbent amount 2.0 g/L, removal real wastewater 91.01%. Also, recycle ex- periments showed that there was 24.11% loss in the biosorption capacity of ESIC for BBR dye after 7 times reuse. Obtained results were consistent with Langmuir and Freundlich isotherm models. All the results demonstrate that ESIC is a natural, recyclable and cost- effective biosorbent for BBR dye removal in wastewater
