Bromamine acid (l-Amino-4-bromoanthraquinone-2-sulfonic sodium) called ABAS for short is an important intermediate in production of reactive dyes and acid dyes. ABAS manufacturing wastewater exhibits very high COD and color. In Chapter One, different treatments of ABAS wastewater, especially biological treatment have been reviewed. Therefore, the significance and background of this study in the paper has been showed.
HP3 screened from active sludge could efficiently degrade ABAS. The dynamic chara...
