INTRODUCTION

1.1 Background study

In this era of globalization, disposal of industrial waste is a great problem for the world’s population. Effluent from industries such as textile industry will result in water pollution, continuously spreading critical diseases. The World Bank estimates that 17 to 20 percent of industrial water pollution comes from textile dyeing and treatment. Textile industry and its dye-containing wastewater are not only undesirable for its colour, but the breakdown of the products also release toxic, carcinogenic and mutagenic substances that threaten human’s health (Suteu D. et al., 2010). Zaharia Carmen and Suteu Daniela (2012) state that, only 10 to 25 percent of textile dyes lost during dyeing process whereas a total of 2 to 20 percent will be discharged directly as aqueous effluent in different environment component.
There are several method used in separating or eliminating industrial wastewater from water bodies. They are adsorption, chemical precipitation, coagulation-flocculation, ionic exchange and several others more. 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 solid. Activated carbon, peat, coal ashes wood chips or wood sawdust can be used as adsorbent in adsorption process but activated carbon is believed to have the best efficiency (Zahari C. and Suteu D., 2012).
Even though activated carbon has the best efficiency, it is expensive and associated with intensive regeneration process. This difficulty has led to search for the use of cheap and efficient alternative materials such as rice husk, bamboo, sugarcane bagasse, ...

...iments that will be conducted later, the following results are to be expected:
i. Activated carbon will be produced from sugarcane bagasse by optimizing acid used in impregnated method, in terms of type and concentration of acid. As in this study, sulphuric acid and phosphoric acid will be used later with concentration of 4%, 10%, 20%, 30% and 40%. ii. From the properties study, the best activated carbon produced will be chosen as the best impregnation method (in terms of acid optimization). iii. From batch experiment, the best condition for activated carbon to remove textile wastewater will be chosen. The best condition for removing contaminants in wastewater will be known in terms of contact time, dosage and granular size of activated carbon used. iv. Activated carbon produced can treat textile wastewater and reduce water pollution worldwide, is to be expected.
