Adsorption through agricultural products such as rice husk, sugarcane bagasse, activated cassava peels, coconut shell, etc. has been extensively studied and found useful and more economical than the conventional treatment system for the removal of toxic metals such as dyes/colour, chromium (Cr), mercury (Hq), copper(Cu), etc.from aqueous solution (Owamah, 2014). Also, the use of microorganisms such as algae, fungi and bacteria for contaminants removal from wastewater has been extensively reported in literature.
