“…Therefore, the removal of MB from wastewaters is very important (Altenor et al 2009;Nezamzadeh-Ejhieh and Karimi-Shamsabadi 2014). Many techniques which are adsorption, chemical coagulation, degradation, solvent extraction, oxidation, membrane filtration are applicable for removal of MB dye from wastewater (Bazrafshan et al 2015;Goyal et al 2018;Hua et al 2017;Ledakowicz et al 2017;Ma et al 2018). Among all these techniques, adsorption is a commonly used dependable method.…”

The use of lichens is insufficient in industry. To the best of our knowledge, there is no study on the use of lichens in the removal of dyes from aqueous media. The aim of this study is to draw attention to the biosorption capabilities of lichens which are natural, renewable and inexpensive sources, and to investigate the usability of nonliving lichen Pseudevernia furfuracea (L.) Zopf. (LPF) in methylene blue (MB) dye removal from aqueous solution. With the green chemistry approach, no chemical treatment was applied to the LPF and it was used as a natural biosorbent for the biosorption. The LPF samples were prepared and characterized and performed batch mode biosorption experiments studying the effect of various parameters on MB biosorption. The experimental data were fitted with four different kinetic models (pseudo-first order, pseudo-second order, Elovich model and intra-particle diffusion) which were evaluated for their validity. Identification of the biosorption mechanism of MB onto the LPF was performed by isotherm studies via three isotherm models [Langmuir, Freundlich and Dubinin-Radushkevich (D-R)], and the parameters of each model were determined. It was concluded that the biosorption rate and yield were high, the type of biosorption of MB onto the LPF was defined as chemical biosorption, and the surface of the LPF was decided energetically heterogeneous. The results indicate that the LPF biomass can be attractive options for MB dye removal from aqueous media.

“…The application of adsorption as a tertiary treatment of textile effluents to reduce COD has been investigated by many authors, even when using more expensive processes. [39][40][41] Harrelkas et al [42] studied textile wastewater treatment by combining several treatments. Combining F I G U R E 7 Scheme illustrating the preliminary mechanism proposed for colour removal from textile wastewater using GO coagulation-flocculation (CF) with microfiltration (MF), ultrafiltration (UF), and adsorption on activated carbon (AC), it was revealed that the CF-MF, CF-UF, and CF-AC combinations guaranteed percentage removal values of colour equal to 65%, 74%, and 50%, respectively.…”

Textile effluent is one of the most hazardous types of wastewater for both the environment and human health when discharged without proper treatment.This work stands out as one of the first to evaluate the parameters for the application of graphene oxide (GO) to treat real textile wastewater. A comparative analysis was conducted to investigate the removal efficiencies of turbidity and apparent colour from raw textile wastewater using GO. The effects of different parameters, such as GO dosage, pH, and contact time were discussed, considering a removal mechanism based on the salting out effect. Results regarding treatment using GO followed by centrifugation showed that in >1 hour nearly 90% turbidity was decreased, and an apparent colour removal efficiency over 76% was recorded, which is twice the value obtained with the conventional treatment applied in textile mills. Over 60% chemical oxygen demand was reduced. Tests using GO followed by sedimentation also revealed promising results, showing removal efficiencies of 66% and 88% for apparent colour and turbidity, respectively. These results suggest that GO could be promising for real wastewater treatment. K E Y W O R D Sapparent colour, graphene oxide, salting out effect, textile wastewater, turbidity

“…Electrocoagulation was proven to be a very effective method for the fast decolorization of textile dyes and also to attain maximum percentage removal capacity [15]. The combined process (chemical coagulation using PAC, electrocoagulation and adsorption process using pistachio nut shell ash) removed the color, chemical oxygen demand (COD) and biological oxygen demand (BOD) by 99%, 98% and 94.2%, respectively [16].…”
