Paper Title
Use of Photocatalytic TechniqueiIn Treatment Of Wastewater Caused by Yarn Dyeing Process in The Textile Industry in Bangpakong, Chachoengsao Province

Abstract
Wastewater from reactive dyeing process is a primary cause to wastewater pollution. This is due to the facts that most types of dyes are organic and soluble; as a result, it is difficult to be treated. This research thus aims to discuss the use of Photocatalytic technique in the treatment of wastewater caused by the textile industry in Bangpakong, Chachoengsao, together with the absorption technique through titanium dioxide and sawdust, and to study the results of the treatment. Water wasted with reactive dye, acid dye, disperse dye, and direct dye will be treated in this study. According to SEM/EDX study, it is found that sawdust are consisted of 63.15% of carbon and 32.33% of oxygen, other minerals, for example, a small amount of potassium and calcium are detected. From SEM photographs and BET surface area analysis, it shows that when sawdust are conditioned through water and 0.1 N HCl, it will dissolve components, for example, potassium and calcium, increasing holes on the surface of absorption materials as a result. From the study, direct and reactive dye reacts satisfyingly to the Photocatalytic wastewater treatment and the absorption method while disperse dye react well to the absorption technique. However, only small amount of acid and basic colours are present in the wastewater; thus, they are not tested. The proper conditions for treating direct dye are the use of 10 g of titanium dioxide per litre for a 6-hour period and the use of 10 g of sawdust per litre for a 2-hour period. For reactive dye, 10 g of titanium dioxide per litre for a 6-hour period and 10 g of sawdust for a 2-hour period are recommended. Lastly, disperse dye wastewater requires 15 g of sawdust per litre and a 4-hour period. In conclusion, Photocatalytic in combination with absorption technique can be employed for wastewater treatment caused by the textile industry.
