The existing water treatment system depending on the rapid filteration has been inefficient in removing the contaminants such as ammonia nitrogen(NH₄^+-N), alkyl benzen sulfornate(ABS), trihalomethane(THM) precursors, UV absorbent materials, color, and so on. An experiment with a pilot-plant was performed in order to find out whether such problem can be overcome by optimizing the configuration of advanced water treatment process such like biological aerated filter(BAF), ozonation, granular activated carbon(GAC), and biological activated carbon(BAC) bed. |
