Treatment of industrial Effluents using polyelectrolyte membranes.
Desalination, 2010Co-Authors: Usha K. Aravind, B. George, M. S. Baburaj, A. P. Thomas, Sabu Thomas, Charuvila T. AravindakumarAbstract:Abstract Wastewater treatment using self-assembled membranes is an upcoming research area and it is believed that this technology is much superior to other conventional membranes. The present study demonstrates the usefulness of chitosan/polystyrene sulfonate (CHI/PSS) based multilayer membranes in the treatment of paper mill and textile Effluents. Membranes were prepared with different number of bilayers (5.5 to 20.5) and the effect of removal of color and COD of Effluents were investigated. The effect of loading of dye and organic matter from the Effluent were studied using UV–Visible absorption spectroscopy. The multilayers were found to be very effective in the removal of color and COD. A considerable reduction in color and COD was observed for the paper mill and textile Effluents. The COD values reduced by 88% and around 70% in case of paper and textile Effluents respectively. The color and COD removal was very efficient for the textile Effluent around neutral and low pH regions.

electrocoagulation for the treatment of textile industry Effluent a review
Journal of Environmental Management, 2013Co-Authors: V. Khandegar, Anil K. SarohaAbstract:Various techniques such as physical, chemical, biological, advanced oxidation and electrochemical are used for the treatment of industrial Effluent. The commonly used conventional biological treatment processes are time consuming, need large operational area and are not effective for Effluent containing toxic elements. Advanced oxidation techniques result in high treatment cost and are generally used to obtain high purity grade water. The chemical coagulation technique is slow and generates large amount of sludge. Electrocoagulation has recently attracted attention as a potential technique for treating industrial Effluent due to its versatility and environmental compatibility. This technique uses direct current source between metal electrodes immersed in the Effluent, which causes the dissolution of electrode plates into the Effluent. The metal ions, at an appropriate pH, can form wide range of coagulated species and metal hydroxides that destabilize and aggregate particles or precipitate and adsorb the dissolved contaminants. Therefore, the objective of the present manuscript is to review the potential of electrocoagulation for the treatment of industrial Effluents, mainly removal of dyes from textile Effluent.

Public perception and health implication of loom-dye Effluent irrigation on growth of rice (Oryza sativa L.) and red amaranth (Amaranthus tricolor L.) seedlings
Environmental Science and Pollution Research, 2020Co-Authors: Md. Arifur Rahman, Md. Abul Khair Chowdhury, Biplob Kumar Saha, Md. Akhter Hossain Chowdhury, K. M. MohiuddinAbstract:Loom-dye Effluent discharge has constituted a major environmental threat to the people of Belkuchi Upazila of Sirajganj District. The present study was conducted to characterize loom-dye Effluents and investigate their health implications by the growth analysis of rice and red amaranth seedlings along with a survey study among the individuals associated with loom-dyeing, weaving, and crop farming activities. A total of twenty-eight loom-dye Effluent samples were collected for physicochemical characterization; among them, only three loom-dye Effluents, i.e. pink, violet, and black dyes, at concentrations of 0, 10, 25, 50, 75, and 100% were applied as irrigation water to rice and red amaranth. The plant growth experiment was laid out following a completely randomized design with three replicas. Chemical analyses of loom-dye Effluents showed the presence of a significant amount of plant nutrients and heavy metals. The mean concentrations of Pb, Cd, Cr, Fe, Mn, Zn, and Cu were 0.938, 0.046, 0.212, 7.109, 0.609, 0.351, and 0.191 mg L^−1, respectively. Among the metals, the concentrations of Pb, Cr, Fe, and Mn were above the recommended limit proposed by the irrigation water guideline value. Application of ≤ 25% pink and violet dye Effluent and ≤ 10% black dye Effluent had significant ( p

Heavy metals in handloom-dyeing Effluents and their biosorption by agricultural byproducts
Environmental Science and Pollution Research, 2018Co-Authors: Kamrun Nahar, Md. Abul Khair Chowdhury, Afzal Rahman, K. M. MohiuddinAbstract:The Madhabdi municipality in the Narsingdi district of Bangladesh is a well-known area for textile, handloom weaving, and dyeing industries. These textile industries produce a considerable amount of Effluents, sewage sludge, and solid waste materials every day that they directly discharge into surrounding water bodies and agricultural fields. This disposal poses a serious threat to the overall epidemic and socio-economic pattern of the locality. This research entailed the collection of 34 handloom-dyeing Effluent samples from different handloom-dyeing industries of Madhabdi, which were then analyzed to determine the contents of the heavy metals iron (Fe), zinc (Zn), copper (Cu), chromium (Cr), manganese (Mn), lead (Pb), and cadmium (Cd). Average concentrations of Fe, Cr, Cu, Pb, Mn, and Zn were 3.81, 1.35, 1.70, 0.17, 0.75, and 0.73 mg L−1, respectively, whereas Cd content was below the detectable limit of the atomic adsorption spectrophotometer. The concentrations of Fe, Cr, Cu, Pb, and Mn exceed the industrial Effluent discharge standards (IEDS) for inland surface water and irrigation water guideline values. A biosorption experiment of the heavy metals (Fe, Cr, Cu, Mn, and Zn) was conducted without controlling for any experimental parameters (e.g., pH, temperature, or other compounds present in the Effluent samples) by using four agricultural wastes or byproducts, namely rice husk, sawdust, lemon peel, and eggshell. Twenty grams of each biosorbent was added to 1 L of Effluent samples and stored for 7 days. The biosorption capacity of each biosorbent is ranked as follows: eggshell, sawdust, rice husk, and lemon peel. Furthermore, the biosorption affinity of each metal ion was found in the following order: Cu and Cr (both had similar biosorption affinity), Zn, Fe, Mn. The Effluents should not be discharged before treatment, and efficient treatment of Effluents is possible with eggshell powder or sawdust at a rate of 20 g of biosorbent per liter of Effluents.
