The following report on the Aeration Facility Project is for your information. This report will be transmitted whenever changes occur to the operation of the aeration facility, and as a result of data monitoring of dissolved oxygen in the Stockton Deep Water Ship Channel.
As a part of ongoing pulse tests, the Aeration
Facility was turned on Monday, July 28, 2008 at about 9:45 a.m.
The system was operated at full capacity with oxygenated water
with a dissolved oxygen (DO) level in the upper 30 mg/l range.
Water was discharged into the Stockton Deep Water Ship Channel
for four full days ending Friday, August 1, 2008 at about 10:15
a.m. In addition, a test was conducted on Wednesday, July 30,
2008 to feed oxygen at a lower pressure to measure if higher oxygen
transfer efficiencies could be attained. Results are still being
analyzed. Thus far, the maximum efficiency achieved has been in
the low 60% range. An efficiency of 80% is hoped to be achieved
through additional optimization testing. The system will be off
for the next three days and will be turned back on Monday, August
4, 2008 at about 9:30 a.m.
