The synthetic dyes used in the textile industry pollute a large amount of water. Textile do not bind tightly to fabric and are discharged as effluent into aquatic environment. As result, continuous discharge wastewater from number industries without prior treatment has significant negative consequences on environment human health. contaminate habitats have potential be toxic organisms, which may enter food chain. This review will discuss effects water bodies, flora, degrade esthetic quality bodies by increasing biochemical chemical oxygen demand, impairing photosynthesis, inhibiting plant growth, entering chain, providing recalcitrance bioaccumulation, potentially promoting toxicity, mutagenicity, carcinogenicity. Therefore, dye-containing should effectively treated using eco-friendly technologies avoid environment, health, natural resources. compares most recent commonly remove dye wastewater, with focus advantages drawbacks these various approaches. is expected spark great interest among research community who wish combat widespread risk organic pollutants generated industries.

Natural dyes have been used from ancient times for multiple purposes, most importantly in the field of textile dying. The increasing demand and excessive costs natural dye extraction engendered discovery synthetic petrochemical compounds. Nowadays, they are dominating market, with nearly 8 × 105 tons produced per year due to their wide range color pigments consistent coloration. Textile industries consume huge amounts water dyeing processes, making it hard treat enormous quantities this hazardous wastewater. Thus, harmful impacts when discharged non-treated or partially treated forms environment (air, soil, plants water), causing several human diseases. In present work we focused on dyes. We started by studying classification which depended nature manufactured fiber (cellulose, protein dyes). Then, mentioned characteristics dyes, however, more negative ecosystem (soil, plants, air) humans. Lastly, discussed applied physical, chemical biological strategies solely combination wastewater treatments. Additionally, described newly established nanotechnology achieves complete discharge decontamination.

Various Approaches for the Detoxification of Toxic Dyes in Wastewater

Processes, Год журнала: 2022, Номер 10(10), С. 1968 - 1968

Use of dyes as well colorants in industrial processes has extensively increased. Effluents from various industries such textile, paint, food, etc. are reported to have a diverse range colorants. The effluents these often released into natural water bodies, causing serious and environmental pollution, which humans other species constantly exposed. Continued changes climate also affected availability for people around the world. Thus, advanced treatments removal harmful contaminants municipal wastewater becoming increasingly important. Removal can be done variety ways, including physical, chemical, biological treatments. These technologies, however, differ terms efficiency, cost, effect. There many technological economic challenges treatment methods currently available. search most suitable strategy successful degradation or is an urgent requirement. Previously published research suggests that use enzymes dye more effective compared traditional techniques. Nanoparticles, with their exceptional physicochemical features, potential tackle problem purification less energy-intensive way. However, extensive standardization would necessity different nanoparticles. Therefore, intense nanoparticle-based technologies may provide much needed solution remediation wastewater.

Biomass-Based Adsorbents for Removal of Dyes From Wastewater: A Review

Frontiers in Environmental Science, Год журнала: 2021, Номер 9

Опубликована: Дек. 9, 2021

Dyes, especially azo dyes contained in wastewaters released from textile, pigment, and leather industries, are entering into natural waterbodies. This results environmental deterioration serious health damages (for example carcinogenicity mutagenesis) through food chains. Physiochemical, membrane processes, electrochemical technology, advanced oxidation reverse osmosis, ion exchange, electrodialysis, electrolysis, adsorption techniques commonly used conventional treatment technologies. However, the limitations of most these methods include generation toxic sludge, high operational maintenance costs. Thus, technological advancements use to remediate effluents. Adsorption using nonconventional biomass-based sorbents is greatest attractive alternatives because their low cost, sustainability, availability, eco-friendly. We present reviewed up-to-date publications on for dye removal. Conceptualization synthesizing state-of-the-art knowledge characteristics, experimental conditions were also discussed. The merits various biosorbents reflected. maximum capacities synthesized order biomass type (algae, agricultural, fungal, bacterial, activated carbon, yeast, others). Surface chemistry, pH, initial concentration, temperature, contact time, adsorbent dose as well ways preparations materials affect biosorption process. Based average capacity, those arranged prioritized. best fit isotherms Freundlich Langmuir models) basic operating parameters removal retrieved. Which adsorbents have greater potential based uptake nature, cost-effectiveness, bulk mono multilayer behavior was including desorption cycles preparation operation implementation this technology forwarded.

Textile Industry Effluent Treatment Techniques

Journal of Chemistry, Год журнала: 2021, Номер 2021, С. 1 - 14

Опубликована: Июль 28, 2021

Dyes and other chemicals laden wastewater is a main environmental concern for increasing the textile industries in many parts of world. Textile consume different kinds manmade dyes or release huge extents highly polluted water into environment. This excessive dye has great impacts on photosynthetic activity aquatic plants animals, example, fish. It may also affect human health due to presence components like heavy metals chlorine dyes. Thus, effluent from must be treated before discharge body. Treatment technologies observed this review paper include biological treatment methods (fungi, algae, bacteria, microbial fuel cells), chemical (photocatalytic oxidation, ozone, Fenton’s process), physicochemical (adsorption, ion exchange, coagulation, filtration). includes hybrid their cost per m3 analysis. There are alternative treatments systems at steps generated operational unit recommend work.
