ABSTRACT Methylene blue contamination in wastewater causes problems in several ways. The presenceofdyes inwater, eveninverylowquantities, retardsphotosynthesis;inhibitsthegrowth of aquatic biota and interferes with gas solubility in water bodies. They cannot be decomposed easily. Therefore, it is highly necessary to reduce dye concentration in the wastewater. The conventional methods for treating dye containing wastewaters are electrochemical treatment, coagulation and flocculation, chemical oxidation, liquid–liquid extraction and adsorption. Adsorption has been shown to be an effective way for removing organic matter from aqueous solutions in terms of initial cost, simplicity of design, ease of operation and insensitivity to toxic substances. From literature survey, it was inferred that there is lesser work on the biosorbents derived from marine bio waste. Hence, an attempt has been made in the present studyto remove Methylene blue dyeusing marine biowaste shells[Crab Shells] entitled.The present study deals with Marine bio-waste shells converted in to biosorbent powder for polluted waste water treatment studies.The effects of pH, contact time, initial dye concentration and dosage on adsorption capacity were investigated.
