탱크내의 잔여 활성탄을 방출하려면 백워쉬 공급수를 사용하거나, 탱크로 공급되는 물을, 탱크하부에서 30 쎈티에서 90 쎈티정도 채워서, 위에 기슬한 활성탄 방출과정을 반복한다.

백워쉬공급수로 채우기 위해서는 개방해야하는 밸브는 A-V11 (탱크 #1), A-V12 (탱크 #2), B-V11 (탱크 #3), B-V-12 (탱크 #4) 이며, 탱크 공급수로 채우려면 개방해야하는 밸브는 A-

V1 (탱크 #1), A-V2 (탱크 #2), B-V1 (탱크 #3), B-V2 (탱크 # 4) 이다

8. After transfer, depressurize vessel with top vent.

활성탄 방출이 완료후, 탱크내부의 압을뺀다

9. After venting, the top or side manways may be opened for vessel inspection or cleaning.

탱크내의 압을 뺀후, 내부의 검사나 청소를 위해, 탱크위 활성탄 투입구나, 탱크옆의 검사구를

활용할수 있다

7.0 Short Term Shutdown (Less than 48 Hours) 단기간 가동 중지 (48

시간이내)

1. Close all vessel valves, open vessel’s top vent valve to relieve thermal expansion pressure build-up.

탱크의 모든 밸브를 잠그고, 열팽창으로 인한 탱크내부의 압력상승을 막기위해 탱크위에서

내려오는 2 인치 공기 배출구 밸브를 개방한다

8.0 Long Term Shutdown (Great than 48 Hours) 장기간 가동 중지 (48 시간

이상)

1. Close all vessel valves, open vessel’s top vent valve and allow venting.

탱크의 모든 밸브를 잠그고, 위에서 내려오는 2 인치 공시 배출구를 개방한다

2. Open bottom drain valve to drain vessel.

탱크하부의 배수 밸브를 개방한다

3. Open low point pipe drains if necessary to drain stagnant water.

탱크내의 잔루 배수를위해서, 파이프 하부에설치된 배수플러그 개방한다

4. Refill vessel with water before starting operation.

정수를 다시 시작하기 전에 탱크에 물을 채운다

9.0 Performance Monitoring (정수과정 모니터링)

1. Collect water sample from lead GAC vessels (SV-02, SV-03, SV-05, or SV-06 [Vessels #1, #2, #3, or #4, respectively]), as appropriate every three months.

3 개월 주기로 선도 탱크의 정수된 물의 샘플을 채취한다. 각 탱크의 샘플밸브는 SV-02

(탱크#1), SV-03 (탱크#2), SV-05 (탱크#3), SV-06 (탱크#4) 이다

2. If lead GAC vessel perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) concentrations exceed 150 nanograms per liter of total PFOA and PFOS individually or combined, then schedule replacement of vessel GAC.

만일 선도탱크의 PFOA 와 PFOS 의 개별 함유량이 리터당 150 나노그램 (ng) 이상이거나, 혹은 PFOA 와 PFOS 의 합친 함유량이 150 나노그램 (ng) 이상일경우에는, 활성탄을 교체하여야 한다.
