Degradation of Organic Substances and Reactive Dye in an Immobilized-Cell Sequencing Batch Reactor Operation on Simulated Textile Wastewater

Textile wastewater generally consists of high organic substances and is strongly colored. Reactive dye has been used extensively in the textile industries. It is water soluble and difficult to remove by chemical coagulation. Removal of organic substances simultaneously with dye can be achieved by a...

Description
Summary:Textile wastewater generally consists of high organic substances and is strongly colored. Reactive dye has been used extensively in the textile industries. It is water soluble and difficult to remove by chemical coagulation. Removal of organic substances simultaneously with dye can be achieved by a biological process. This study aims to investigate the treatability of the organic substances and reactive dye in immobilized-cell sequencing batch reactors (SBR). Three different supporting medias namely activated carbon, steel slag and plastic were used. The performance of each reactor was compared with a conventional sequencing batch reactor. The simulated textile wastewater containing the reactive azo dye Procion Red H-E7B of a concentration of 40 mg/L and COD 300 mg/L, was fed into the reactors. The supporting media in the SBR system, it will enhance the capability of COD and dye operating of the SBRs consisted of 5 periods; Fill 1.5 h, React (anoxic:oxic) 20 (14:6) h, Settle 1.5 h, Draw 0.5 h and Idle 0.5 h. The results revealed that by adding removal. During a steady state of operation, the COD and dye concentrations of each period were investigated. In addition, the prolonged anoxic period brought about better decolorization efficiency.
