(3) TKN Removal Efficiency<br />
The TKN Removal was high due to <strong>th</strong>e presence <strong>of</strong> ammonia stripping process. The<br />
TKN <strong>of</strong> <strong>th</strong>e influent was around 1,700 mg/L. The TKN <strong>of</strong> <strong>th</strong>e stripped le<strong>ac</strong>hate was found<br />
to be around 320-340 mg/L for 16 and 24 h HRT. The TKN <strong>of</strong> <strong>th</strong>e influent, stripped<br />
le<strong>ac</strong>hate and effluent along wi<strong>th</strong> effluent ammonical concentration for 16 and 24 h HRT in<br />
<strong>th</strong>e BMBR and YMBR systems is given in Figure 4.32 and 4.33, respectively.<br />
