| Abstract |
| Nowadays, Water is deteriorating with several reasons such as increase of wastewater which is flowed into river and limitation of water resource. In this study, reuse water system was configurated using submerged membrane bioreactor (SMBR) system consisted of anoxic, selector, and aerobic tank with membrane to concentrate on plans for securing of water resource by reusing wastewater treatment effluent. Estimation of application for reuse water and optimized HRT was found by comparing with the characteristics of treatment with HRT change. Also, we experimented the 1st floor and 2nd floor membrane to find more effective operating condition in the SMBR system. Specific characteristics of SMBR system was satisfied with the standard of reuse water as below 10㎎/L of BOD, below 5㎎/L of COD, 0 ㎎/L of SS without regard to change of HRT ranging from 2.3hr to 11.6hr. Optimized HRT was 2.3hr and air flow rate of the 2nd floor membrane module could be reduced 28.5% lower than that of the 1st floor membrane. |
