Direct Conclusion
First, identify the type of scale and its location to determine the cleaning method. If scaling recurs, cleaning only addresses the immediate issue; the water treatment strategy must be adjusted accordingly.
Judgment Criteria
- 01
Open the inspection port to observe the scale color and hardness: a white hard layer typically indicates calcium/magnesium deposits; black sludge suggests bacterial/algal growth and suspended solids; reddish-brown deposits usually signify corrosion products.
- 02
After cleaning, record the terminal difference, flow rate, and temperature difference as baselines. If these metrics deteriorate again within two to three months, it indicates that the scaling rate is not under control.
Applicable Conditions
Preliminary assessment for plate, shell-and-tube, and copper tube heat exchangers.
