Nalco 8457

| Problem | Possible Cause | Corrective Action | |---------|----------------|--------------------| | High orthophosphate | Overfeed or low blowdown | Reduce feed rate, increase blowdown | | Rising corrosion rates | Underfeed, pH excursion | Check pump calibration, adjust pH | | White phosphate scale | High calcium, high pH (>8.5), overfeed | Lower pH, reduce feed, add polymer | | Copper corrosion | Low azole content, ammonia in water | Verify product integrity, test for ammonia | | Fouled heat exchanger | Poor dispersion, high suspended solids | Increase blowdown, clean then re-passivate |

– Fewer unplanned shutdowns due to tube leaks or fouling.

Unlike older filming amine technologies that could sometimes form sticky deposits or "gunk balls" if overtreated, modern formulations like 8457 are designed for cleaner application, reducing the risk of fouling when applied correctly. nalco 8457

While neutralizing amines are the standard for many low-pressure systems, Nalco 8457 is often the superior choice for systems facing specific challenges, including:

for use as an off-line membrane cleaner. Note that systems must be thoroughly flushed after cleaning and before being used for drinking water. Regional Compliance | Problem | Possible Cause | Corrective Action

Protecting your condensate return system is not just about preventing leaks; it is about safeguarding the overall efficiency of your plant. Nalco 8457 represents a powerful tool in the water treatment arsenal, moving beyond simple pH adjustment to provide active, physical protection of metal assets.

If possible, include a photo of a clean vs. corroded fuel pipe or a professional image of a storage facility to break up the text. Note that systems must be thoroughly flushed after
