Deionized water temporarily turned off during week 37 - Biomedicum
Biomedicum's clean water facility is being rebuilt with new filters to ensure high quality of the deionized water. As a result, the clean water must be turned off periodically during week 37 for floors 6-9.
The system must also be sanitized after the service from Friday 13 September to Sunday 15 September, and during that time the clean water cannot be used.
Quarter A and B
- Conductivity: OK (0.28 microSiemens)
- TOC: OK (29 ppb)
Quarter C and D
- Conductivity: OK (0.14 microSiemens)
- TOC: NOT OK (141 ppb) The TOCvalue is estimated to be below threshold (50ppb) Tuesday September 17. Result will be posted here.
The stop lasts for three hours for individual quarters (see table below), and it is then not possible to use the deionized water from the green taps in the apparatus rooms. Note that also equipment connected to clean water, for example water purifiers, cannot be used during the shutdown.
After service, the clean water system must be sanitized. This takes place Friday - Sunday week 37, and during this time all equipment must be disconnected from the system (turn off and close the water valve) and the water must not be used. After sanitation, the TOC-value of the water will be analyzed and the result is expected at the beginning of week 38. An e-mail will be set out to Biomedicum staff with the result.
