CHAPTER 1INTRODUCTION1.1 Background StudyIn the era of globalization, the disposal of industrial waste is a great problem for the world's population. Effluents from industries such as the textile industry will cause water pollution, continually spreading serious diseases. The World Bank estimates that 17 to 20 percent of industrial water pollution comes from textile dyeing and processing. The textile industry and its wastewater containing dyes are not only undesirable due to their color, but the degradation of the products also releases toxic, carcinogenic and mutagenic substances that threaten human health (Suteu D. et al., 2010) . Zaharia Carmen and Suteu Daniela (2012) state that only 10 to 25 percent of textile dyes are lost during the dyeing process, while a total of 2 to 20 percent will be released directly as aqueous effluent into different environmental components. Several methods are used to separate dyes. or the removal of industrial wastewater from water bodies. These are adsorption, chemical precipitation, coagulation-flocculation, ion exchange and many others. Adsorption is one of the effective methods with potential application in textile wastewater treatment. In this method, soluble organic dyes from wastewater will be attached to the highly porous surface of the solid. Activated carbon, peat, coal ash, wood chips or sawdust can be used as adsorbents in the adsorption process, but activated carbon is considered to have the best efficiency (Zahari C. and Suteu D., 2012). Although activated carbon has the best effectiveness, it is expensive and is associated with an intensive regeneration process. This difficulty has led to research into the use of cheap and effective alternative materials such as rice husk, bamboo, sugarcane bagasse, ...... middle of paper ...... iments which will be carried out later, the following results are to be expected:i. Activated carbon will be produced from sugarcane bagasse by optimizing the acid used in the impregnated method, in terms of acid type and concentration. As in this study, sulfuric acid and phosphoric acid will be used later with concentrations of 4%, 10%, 20%, 30% and 40%. ii. From the study of the properties, the best activated carbon produced will be chosen as the best impregnation method (in terms of acid optimization). iii. From a batch experiment, the best conditions for activated carbon to remove textile wastewater will be chosen. The best conditions for removing contaminants in wastewater will be known in terms of contact time, dosage and granular size of the activated carbon used. iv. The produced activated carbon can treat textile wastewater and reduce water pollution worldwide, it is expected.
