| Abstract |
It is very important to determine the reaction time in the process which is used to intermittent aeration system. This study was performed to evaluate the applicability of ORP(Oxidation Reduction Potential) for determining the optimum reaction time in SBR. During the aerobic phase, "ammonia valley"^(5) was shown remarkably in ORP curve, and "nitrate valley" was also conspicuous in anoxic phase. But during anaerobic phase, there is no special valley in ORP curve. Therefore we have used ORP slope curve, which made it possible to find the end point of P-release. It has been concluded that ORP is a useful and reliable parameter to determine reaction time and that it is possible to optimize reaction time using ORP curve and ORP slope curve in SBR. |
