Calinration Run – January 5
th
A dry run of the anticipated testing will be performed on January 5
th
. During the dry run, we plan
to do the following:
1. Complete the installation of the test skid, sample piping, and low-level TSS set-up.
a. Change out three DP meters from the current 0-15 psid gauges to 0-30 psid gauges
b. Connect tubing from the final three sample ports to the overflow buckets
c. Connect tubing from the overflow buckets to the TSS sample filter pumps, 0.45um
filter, and measurement jugs.
