- Incrustation: Caused by minerals or cleaning agents, leading to crust formation.
- Scaling: Results from deposits like calcium carbonate or silicates.
- Sediment: Includes corrosion products and organic matter such as silt or microalgae.
- Biological Growth: Microorganisms like bacteria and protozoa thrive in humid conditions.
| Type of Fouling | Description | Causes |
|---|---|---|
| Incrustation | Crust or coating on surfaces. | Processed fluids, minerals, cleaning agents. |
| Scaling | Mineral deposits like calcium carbonate. | Hard water, high temperatures. |
| Sediment | Corrosion products and organic matter. | Metal oxides, silt, microalgae. |
| Biological Growth | Microorganisms on surfaces. | Bacteria, nematodes, protozoa. |
Preventing fouling involves regular maintenance, water treatment, and using materials resistant to deposits. Monitoring water pH and minimizing surface roughness also help reduce fouling risks.
Effective Cleaning Methods for Long-Term Efficiency
Cleaning heat exchangers regularly ensures long-term efficiency. A structured cleaning process includes:
- Circulate a cleaning solution to maintain a pH of 2–3.
- Neutralize the solution to a pH of 5 or higher.
- Rinse with fresh water until the pH reaches 6–7.
- Passivate surfaces with a product like Tube Bright to resist scaling.
- Inspect for debris and flush if necessary.
For mineral deposits, Scalzo (hydrochloric acid-based) is effective but unsuitable for stainless steel. Instead, CA-100 (citric acid-based) offers a gentler alternative. Regular cleaning not only restores heat transfer efficiency but also prevents costly repairs.
Corrosion Resistance
