Hello All! This blog’s main function will be to inform customers about the proper procedures of water chemistry tests for boilers, cooling towers and other closed loop systems.
North De-Alkalizer’s
Gentlemen, Pat and I would like for us to continue to test the De-Alkalizer tanks for conductivity every day. We also need to continue to test the make-up water (for the DA tanks) in the north utility for hardness only. These test are available in the E-Service Operator logs. Please …
New Pyxis & Oakton
Two new Pyxis units were delivered yesterday. These units will give us inhibitor (polymer) concentration and conductivity for the towers. There is one unit that is open and calibrated, the other unit can be taken to the north and may need to be calibrated. The Oakton pH device is reading …
ORP vs. Free Chlorine Sensors
We use ORP to control the bleach feed in the cooling towers and we use Free Chlorine Sensors in the retorts to feed bleach. Why the difference? ORP is less accurate. Reading ORP is like telling time by where the sun is in the sky. Not very precise, but very …
pH Electrode Testing
Zach and I found an Oakton pH Electrode in the South Utility Room. The green and white Oakton device was reading accurately yesterday. So I believe this is our best way to calculate pH for the COOLING TOWERS. Since this device is pretty fragile, it may not be the best …
pH Sensor
As you know the pH is critical to the successful operation of cooling water treatment. Not enough acid and we get scale, too much we can corrode the system.For the most part the acid feed is controlled by the pH sensor so it needs to be accurate and responsive. When we do …
