김미경 Migyoeng Kim , 이호식 Hosik Lee
Abstract
In this study M2LE process which is combined membrane and automatic coagulation control system, to remove phosphorus and nitrogen in small scale sewage treatment plant. By applying an automatic coagulation control system, the amount of coagulant injected was reduced by up to 40%, and the removal efficiency of T-P was 98.4%, BOD 99%, and SS 100%. In addition, in order to compensate for the nitrogen removal problem, 72% removal efficiency of T-N was obtained by changing the operating conditions of the process.
