“…This original methodology is taking place as a significant, large-scale solution for textile industries due to the speed of cleaning and reduction of certain pollutants to near-zero levels [74]. Nanomaterials could be synthesized based on plant extracts [75,76], metals and metal oxides [77,78], carbon [79] and nanocomposites [80]. However, it is important to know that the elimination of nanoparticles after water purification needs to be addressed [81].…”

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

“…A cor é um parâmetro utilizado para avaliar a eficiência de remoção de qualquer processo de tratamento, principalmente quando os efluentes a serem tratados apresentam uma coloração intensa como é o caso de efluentes têxteis (CHEN et al, 2011;ZALESCHI et al, 2014;MBACKÉ et al, 2016). A Figura 2 mostra a variação da cor em relação ao tempo de tratamento de EC utilizando o conjunto de eletrodos de alumínio sem modificação e modificados por deposição a plasma.…”

“…The dyestuff wastes have given rise to concern due to their overuse and are a serious hazard to public health and environment if discharged without proper treatment . Nowadays, various strategies have been proposed for the removal of dyes including adsorption, precipitation and coagulation, photocatalytic degradation and membrane filtration . Among these methods, membrane filtration is one of the most attractive techniques because of its simple operation and low cost.…”

a] 3-(Trimethoxysilyl)-1-propanamine (APTMS) modified glass fiber membrane (APTMS-GF) was prepared via chemical bonding with different volume ratios (APTMS : methanol = 1:20, 1:10, 1:5), which was called APTMS-GF-1, À 2 and À 3, respectively. For congo red (CR) with the concentrations ranging from 5 to 45 mg L À 1 , the removal efficiencies were up to above 95% by filtration with APTMS-GF composite membranes, but there was no distinct difference in removal capacity with increasing the volume ratio of APTMS. More importantly, on account of the electrostatic interaction, APTMS-GF composite membrane could selectively separate and recycle neutral bromophenol blue (BPB), cationic methylene blue (MB) and anionic methyl orange (MO) from binary systems including BPB/CR, MB/CR, and MO/CR, respectively. Under the static adsorption, the adsorption process of CR on the APTMS-GF composite membrane was better fitting with the pseudo-second-order kinetic model (R 2 = 0.992) due to the electrostatic interaction, which was confirmed by the effects of inorganic ions and pH in solution. The structural advantage of glass fiber membrane with micropores made all of filtration fulfilled under atmospheric pressure in comparison to the reported membranes. As a result, this work provides a feasible method for fabricating the economic membrane in removing dyes.[a] J.
