A green approach for the treatment of dye and surfactant contaminated industrial wastewater

Abstract

Synthetic dyes, particularly reactive and acid dyes, are commonly used in the textile industry because of their advantages as excellent color fastness and brightness. Also, surfactants are used for an increment of coloring success in the textile industry. One of the major problems concerning textile wastewater is the treatment of the effluents containing both dyes and surfactants. Biological treatment systems are recommended as useful, economic and eco-friendly methods for treatment of industrial wastewater. The purpose of this study was to investigate the binary removal of a textile dye and a surfactant by growing Aspergillus versicolor culture in molasses medium. The effect of dye and surfactant concentration on the removal of dye and surfactant was determined. This study resulted that 100% of the surfactant and dye molecules removed together with the formation of a dye-surfactant complex by fungus. It is concluded that binary removal systems are very efficient for industrial wastewater treatment.

Multimetal bioremediation from aqueous solution using dead biomass of Mucor sp. NRCC6 derived from detergent manufacturing effluent

“…The augmentation in industrial activity is important for the economic development of countries, but it causes environmental and health problems owing to its toxic effluents (Ahmed et al 2021 ; Gül 2020 ). Globally, the detergent industries have been prioritized as one of the most polluting.…”

Evaluation of effluent post-treatment by slow filtration and adsorption with activated carbon produced from spent coffee grounds in surfactant removal in sewage treatment

“…To measure the level of pollution and contamination, environmental legislation uses some quality indicators in samples collected, such as oils and greases, surfactants, organic matter, or phosphorus (Metcalf and Eddy, 2014). Among these parameters, surfactants stand out for being widely used in industries, and daily in households as a detergent; in this way, surfactants are among the main pollutants found in sewers (Gül, 2020).…”

“…The significant use of detergents in Brazil and the lack of domestic sewage treatment in urban regions have caused undesirable environmental effects (Gül, 2020). The presence of these can cause the inhibition or paralysis of the natural or artificial purification due to the formation of foams, disturbances in the oxygen conduction through the membranes of the aquatic organisms, and the eutrophication of surface waters due to the presence of phosphates present in the surfactants (Costa et al, 2007).…”

Dispersion of Graphene Using cetyltrimethylammonium bromide (CTAB): Dye Removal and Characterization Studies

“…Surfactants are the surface-active agents which are commonly used in industrial applications [1]. Most studies emphasized that surfactants were used in coloring the products to improve color effluents due to their toxic effects on the health of living organisms and also the environment [5].…”
