Abstract

Wastewater containing dyes presents a serious problem due to its high toxicity which leads to creating enormous environmental pollution and ecological hazards. Therefore the removal of the high stable dyes from the textile effluents is of major importance. The purpose of this study is to remove the reactive dye Procion Blue 2G from textile dye solution by biosorption process using immobilized cells of Pseudomonas aeruginosa and Phanerochate chrysosporium. It was found that maximum dye uptake is 1.648 mg g-1 of bead for P. aeruginosa and it is 1.242 mg g-1 of bead for P. chrysosporium. Both the results are derived from higher initial dye concentration (100 mg L-1) and high cell concentration (in terms of volume of inoculum 20 mL) and at low mass of biosorbent (5 g of bead). Comparatively better results are produced by the beads having the cells of P. aeruginosa than P. chrysosporium. Further, due to the cell immobilization, both the cell beads can be utilized repeatedly in continuous reactors by selecting suitable eluent in industrial scale with the advantage of avoiding wash out of cells.

Highlights

Concentration higher than 1 mg L−1 and an average concentration of 300 mg L−1 has been reported in Textile industries consume large volumes of water and effluents from textile manufacturing processes chemicals for wet processing of textiles

Summary

Introduction

Concentration higher than 1 mg L−1 and an average concentration of 300 mg L−1 has been reported in Textile industries consume large volumes of water and effluents from textile manufacturing processes chemicals for wet processing of textiles. Many dyes are because of their ease and cost-effectiveness in synthesis, believed to be toxic carcinogenic or to be prepared firmness, high stability to light, temperature, detergent from known carcinogens such as benzidine or other and microbial attack and variety in color compared with aromatic compounds that might be formed as a result of natural dyes. This has resulted in the discharge of highly microbial metabolism There are three principle advantages of biological technologies for the removal of pollutants; first, biological processes can be carried out in situ at the contaminated site; Second, bioprocess technologies are usually environmentally benign (no secondary pollution) and third, they are cost effective
