1. Verify that the process mix tank is sanitized and dry. To the mix tank charge 90% of 336701 (Deionized Water). Ensure that the water temperature is 15°C-35°C. Take a sample from the mix tank to the Quality Control lab (QC) and test for the following:
- Resistivity must be 150,000 ohms minimum.
- pH range between 5.0-7.0
Note: The hydration of the Hydroxyethyl Cellulose (338080) is dependent on water pH and temperature.
2. Start agitation once the water level has reached top of the highest impeller blade. Set agitator speed to maintain good surface movement.
