The mechanism of Methylene Blue adsorption on biosolid (waste sludge), has been studied through batch experiments. The effects of various experimental parameters, such as pH (3-11), biosolid dosage (1-10 g/l), contact time (5-1440 min) and initial dye concentration were investigated. The results showed that the dye removal increased with increase in the initial concentration of the dye and also increased in amount of biosolid used and initial pH. Adsorption data was modeled using the Freundlich adsorption isotherm. The results show that biosolid could be employed effective and low cost material for removal of dyes and colour from aqueous solution.
