The textile dye industry is the largest consumer of dye stuffs. During the coloring process a large amount of synthetic dye does not bind and is lost to the waste system. These dyes are difficult to remove in conventional wastewater treatment processes and can be transported easily through sewers and rivers especially because they are designed to have high water solubility. The effluent streams from these textile industries leads to serious water pollution problems. For separation of dyes from these effluent streams, coagulation and adsorption technique is used in this study. Coagulation is the process of settling of suspended particles and subsequent removal of turbidity, Adsorption is a surface phenomenon in which the liquid phase solutes in liquid phase are adsorbed on the surface of the adsorbents. Adsorption using natural adsorbents is more feasible and economical as the natural adsorbents are available in bulk and majorities are usually waste products. Coagulation and Adsorption can be done using lab apparatus such as jar apparatus and orbital shaker with constant stirring where the adsorbent and dye solutions are intimated for a specific period. Coagulant and Adsorbent used in this study are zee maize and sugarcane leaves . Different parameters were altered during the experimentation such as coagulant and adsorbent dosage, time of contact and keeping temperature constant. Coagulation and Adsorption is a low-cost waste water treatment process and is comparatively economical than advanced oxidation processes and filtration processes. The optimum coagulant dosage was 2.5 ml in 1000 ml dye sample, Coagulation using zee maize has achieved upto 70% of removal of turbidity using jar test apparatus .Adsorption using sugarcane leaves has gained up to 98% removal of colour using orbital shaker .
