The efficacy of inactivation and control performance of trihalomethane production are investigated in the pretreatment process with individual application ofc hlor ine, chloramine s and potassium permanganate, and bined application of potassium permanganate with c hlor ine or chloramine s. The results show that the effectiveness ofc hlor ine inactivation is extremely affected
