Abstract
The purpose of this study is the evaluation of treating capacity of the BM (Beneficial Micro-organism) lab scale tests for steel industrial waste water. The test was designed on similar condition with field facility and performed with three kinds of waste water as follows
1) Fish farming waste water.

2) Steel industrial waste water.

3) Mixed waste water ( Fish farming and steel industrial waste water).

AS the result of test, the average BOD removal efficiency rate was 91% and T-N was 83% at low level of C/N rate. It was confirmed that the amount of sludge generation was affected by the MLSS concentration of the system which was in accordance with the removal efficiency rate for each waste water. As the MLSS concentration was increased, the amount of sludge generation was increased at initial time. But the sludge generation rate was decreased as time goes by because the group of BM was mainly activated.

As the result, the enough possibility of the treating BOD, T-N and Sludge reduction with BM lap scale equipment was confirmed.
