การกำจัดสีน้ำทิ้งจากอุตสาหกรรมฟอกย้อมสิ่งทอ โดยกระบวนการตกตะกอนทางเคมีด้วยโพลีเมอร์ / พัชราภรณ์ โพธิ์แจ้ง = Color removal from textile dyeing wastewater by chemical coagulation with polymers / Patcharaporn Pojang
The objective of this experiment was to evaluate the color removal efficiency from dye solution prepared in the laboratory by chemical coagulation with 2 cationic polymers (Lamfloc 1525 and Zentrifloc 95). Alum was used as coagulant to compare, the color removal efficiency from textile effluent collected from sites with cationic polymer together with anionic polymer (Lamfloc 7985). In this study 2 kinds of dyestuff, reactive and vat, and 2 tones, yellow and blue, were used. It was found that Lamfloc 1525 is more efficient than Zentrifloc 95. For removing color from textile effluent, Lamfloc 7985 has little enhancement when used with Lamfloc 1525 and Lamfloc 1525 is more efficient than alum. The efficiency of Lamfloc 1525 is about 90%.
