Dye-containing wastewater is one of the main environmental challenges that can cause health issues. It is crucial to remove the dyes from wastewater before its discharge into the environment. This study aims to evaluate the efficiency of aptenia cordifolia mucilage in removal of anionic dyes from textile wastewater via coagulation and flocculation process. To this goal, the effect of different ...

textile industry is the major source of water consumption and wastewater pollution.there are various treatment techniques to remove textile wastewater pollution. coagulationflocculation is a widely used process to remove pollution due to suspended particles. in this research, different coagulants like alum, lime, fecl3, feso4 and mgcl2 were applied to select the suitable ones with optimum remov...

In the present study, silica aerogel- egg shell was synthesized for dye removal of colored wastewater. The nano composite structure was characterized by Fourier transform infrared spectra FTIR and scanning electron microscope SEM.The ability of nano composite absorption was assessed for removal basic violet 16BV16 dye from aqueous solutions and was compared with two other adsorbents such as egg...

Background and purpose: Textile dye effluents have some potential risks which require effective treatment before discharging into the environment. Advanced oxidation processes can remove pollutants faster than other processes due to active hydroxyl radical production; therefore, increase the efficiency of dye removal. This study was aimed at investigating dye removal process using UVA/ZnO and U...
