Abstract Most of the dyes are carcinogenic and mutagenic in nature. Plants are potential candidates to remediate textile dye wastewater from contaminated sites. The present study aimed toscreen potential plant species for removal of synthetic dye solution of triarylmethane dye Methylene Blue (MB) and diazo dye Congo Red (CR). Six plant species were screened for their phytoremediation ability for the removal of dyes present in synthetic wastewater. Six plants selected for screening areTrachyspermum ammi L. (T. ammi), Tagetes erecta L. (T. erecta), Hibiscus rosa-sinensis L. (H. rosa- sinensis), Chrysanthemum indicum L. (C. indicum), Bryophyllum fedtschenkoi (B. fedtschenkoi), Catharanthus roseus L. (C. roseus). The phytotreatment of dyes was done up to 40 hfortwo different concentrations of dyes 10 mg L− 1 and 20 mg L− 1. Among these plants, the maximum decolouration was obtained from T. ammi plant followed by B. fedtschenkoi plant. Both of these plants showed active growth even after the phytoremediation process. T. ammi decolourised the MB dye 99% (10 mg L− 1) and 86% (20 mg L− 1) while the decolourisation of the CR dye solution was up to 95% (10 mg L− 1) and 84% (20 mg L− 1).T. ammi found to have maximum potential among screened plants for the removal of MB and CR dye from synthetic dye solution and can be used for decolouration of synthetic dye wastewater.

Abstract Most of the dyes are carcinogenic and mutagenic in nature. Plants are potential candidates to remediate textile dye wastewater from contaminated sites. The present study aimed to design an efficient hydroponic system to screen potential ornamental plant species for removal of synthetic dye solution of triarylmethane dye Methylene Blue (MB) and diazo dye Congo Red (CR). The six plants selected for screening are Trachyspermum ammi, Tagetes erecta, Hibiscus rosa-sinensis, Chrysanthemum indicum, Bryophyllum fedtschenkoi, and Catharanthus roseus. The phytotreatment of dyes was done up to 40 h for two different concentrations of dyes, i.e., 10 and 20 mg L− 1. Among screened plant species, the maximum decolorization was obtained from T. ammi followed by B. fedtschenkoi. Both plant species showed active growth in indigenous designed hydroponic system even after the phytoremediation process. T. ammi decolorized the MB dye 99% (10 mg L− 1) and 86% (20 mg L− 1) while the decolorization of the CR dye solution was up to 95% (10 mg L− 1) and 84% (20 mg L− 1). T. ammi was found to have maximum potential among screened plants for the removal of MB and CR dye from synthetic dye solution when kept in designed hydroponic system and can be used for phytoremediation of wastewater contaminated with synthetic dyes.

The high concentration of salt in textile dye wastewater is one of the limiting factors for evaluating an effective biodecolorization system. Thirty-nine strains of salt-tolerant bacteria were screened for their ability to decolorize azo dyes (cationic blue 41) in the presence of 10% NaCl (w/v). Among them, C15-3 was the most effective strain for decolorizing synthetic dye wastewater. Due to the advantages in the use of immobilized cells over other textile wastewater treatments, the entrapment procedure was selected as it generated preferable conditions for dye decolorization. The ratio suitable for the whole cell entrapment technique was 1% (w/v) alginate and 2.5% (w/v) gelatin. In decolorization batching, the immobilized cells were advantaged over free cells for dye removal over a range of pH and temperatures. Synthetic dye wastewater was decolorized by the immobilized cells in the pH 4.0-10.0 range (pH 4.0-8.0 for whole cell system). The immobilized beads were more effective in the removal of synthetic dye at 50°C (optimal temperature) when compared to free cells (optimally at 40°C). Tests revealed that the decolorization products were less phytotoxic when compared to undecolorized azo dye. Immobilized cells were reusable in 4 cycles at pH 7.2 and 37°C, indicating that the addition of immobilized halotolerant cells may be a suitable treatment for industrial effluents in the breakdown of azo dyes.

Term Operation

Textile wastewater is contaminated by reactive dye causing unattractive levels of wastewater color, high pH and high salt content when discharged into public water systems. Decolorization of textile wastewater by plant, phytoremediation, is an alternative, sustainable method which is suitable for long term operation. Narrow-leaved cattails are one species of wetland plant with efficiency for decolorizing and remediating textile wastewater. In addition, chemical oxygen demand (COD) can be lowered and dye residue can be removed. The plant also showed a good salt tolerance even after being exposed to a salt solution for 15 days. The narrow-leaved cattails were set up in a constructed wetland model with a vertical flow system operating from bottom to top for synthetic reactive dye wastewater (SRDW) removal. Narrow-leaved cattails could achieve the removal of SRDW at approximately 0.8 gSRDW m−2 day−1. Decolorization of SRDW by this plant was approximately 60%. The advantage of this method is that it is suitable for textile wastewater management and improvement of wetland. These plants could lower COD, remove dye, sodium and total dissolved solids (TDS) whereas other biological and chemical methods could not remove TDS and dye in the same time. These results suggested that the spongy cell structure of this plant has the ability to absorb large amounts of water and nutrients. Physico-chemical analysis revealed increasing amounts of sulfur, silicon, iron and calcium in the plant leafs and roots after exposure to wastewater. Proteins or amide groups in the plant might help in textile dye removal. Regarding decolorization, this plant accumulates dye in the intercellular space and still grows in this SRDW condition. Hence, it can be noted here that narrow-leaved cattails are efficient for textile dye wastewater treatment.
