Treatment of textile wastewater is challenging because the water contains toxic compounds that have low biodegradability. Dyes, detergents, surfactants, biocides and more are used to improve the textile process and to make the clothes resistant to physical, chemical and biological agents. New technologies have been developed in the last decades and in particular Advanced Oxidation Processes (AO...

The objective of this study was to investigate the capacity of decolorization and detoxification of the textile dyes Reactive Red 198 (RR198), Reactive Blue 214 (RB214), Reactive Blue 21 (RB21) and the mixture of the three dyes (MXD) by Penicillium simplicissimum INCQS 40211. The dye RB21, a phthalocyanine, was totally decolorized in 2 days, and the others, the monoazo RR198, the diazo RB214 an...

A strain LN07 with high laccase yield was identified as basidiomycete fungus Lepista nuda from which a white laccase without type I copper was purified and characterized. The laccase was a monomeric protein with a molecular mass of 56 kDa. Its N-terminal amino acid sequence was AIGPAADLHIVNKDISPDGF. Besides, eight inner peptide sequences were determined and lac4, lac5 and lac6 sequences were in...

Dyes are synthetic organic compounds widely used in various industries such as, textile, leather, plastic, food, pharmaceutical, and paints manufacturing industries. Coloured effluents are highly toxic to the aquatic life and mutagenic to humans. Wastewater containing dyes has become an important issue demanding serious attention. Among the synthetic dyes, azo dyes are the largest and most wide...

Microorganisms dead or alive are successfully exploited for bioremediation of xenobiotics by biosorption. Textile effluents are among the most difficult-to-treat wastewaters, due to their considerable amount of recalcitrant and toxic substances. Fungal biosorption is viewed as a valuable additional treatment for removing pollutants from textile wastewaters. The overall economics of the biosorpt...

The aim was to assess the ability of microcosms (laboratory-scale shallow ponds) as a post polishing stage for the remediation of artificial textile wastewater comprising two commercial dyes (basic red 46 (BR46) and reactive blue 198 (RB198)) as a mixture. The objectives were to evaluate the impact of Lemna minor L. (common duckweed) on the water quality outflows; the elimination of dye mixture...

Effluent from the textile industry contains toxic compounds. These compounds contaminate the surface water, thereby making it unfit for irrigation and drinking. Since farmers use water from the rivers for agricultural purposes and the residents of the town, use both the surface and underground water from the same area as potable water, it is quite unsafe to discharge this effluent into water bo...

BACKGROUND Many dyes can be considered emerging contaminants. The most widely used dyes belong to the class of azo compounds, some of which are known to have toxic and genotoxic properties. They are used in great quantities in textile activities and are of environmental concern because of their potential discharge in water. Planarians have been successfully used as test organisms in hazard eval...

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 c...

    Background & Aims of the Study: Textile wastewaters are very various in chemical qualities. In other words, these industries are one of the largest producing dyes compounds; therefore their treatment is so complex and difficult. The aim of this study was to evaluate the potential removal of Reactive Red 198 and Blue Reactive 19 from synthetic solution by Acaciatortilis shu...
