The use of low-cost adsorbent has been investigated as a replacement for the current expensive methods of removing dyes from wastewater like chemical degradation, advanced oxidation processes, adsorption, precipitation, biodegradation and chemical coagulation. Fly ash generated in Thermal Power plant and other industries which are extensively using coal is collected and converted into a low-cost adsorbent. The highly porous Fly ashes will be utilized to treat colored effluent of a dyes manufacturing plant. Color in the dyes is resulted to reacted-unreacted chemicals. Such type of effluent content Organic Carbons, turbidity and TSS. Adsorption studies was carried out for different temperatures, pH's, and adsorbent doses. In comparison to other low-cost adsorbents, the sorption capacity of the material under investigation is found to be comparable to that of other commercially available adsorbents used for the removal of cationic dyes from wastewater. The Fly ash was activated by chemical treatment by N/2 H2SO4. Batch adsorption experiments were performed as functions of adsorbent doses, initial dye concentration, contact time, and pH. The percentage of colour removal was increased with increasing contact time and adsorbent doses. Chemical oxygen demand (COD) reduction was increased with increasing contact time and adsorbent doses. Maximum removal of colour and Chemical oxygen demand (COD) have been taken place in acidic medium (pH=5
