Beetroot was used to clean water contaminated by methylene Blue (MB). Parameters such as particle size of fibers, initial concentrations, pH of the solutions and rates of effluent were studied to optimize the conditions of removal dyes from industrial wastewater. It has been observed that the efficiency of dyes removal increases when fiberÂ’s size decreases (from 100 to 50 microns). The pH value to remove maximumofmethylene blue is 6.5. Adsorption parameterswere determined using bothLangmuir and Freundlich isotherms. The chemical modification of fibers by an anionic surfactant such as sodium dodecyl sulfate (SDS) increases the efficiency of the dyeÂ’s elimination two times.
