Boiler Water Treatment

Nalco was built on boilers, and more than 80 years ago, we began treating boilers for railroads and industry. And that long-term commitment to developing the most innovative boiler water treatment technologies in the industry continues today. It is a result of our desire to improve your competitive advantage and decrease your total operating costs.

 

A single day of lost steam production can cost you much more than the cost for one or two years of our boiler treatment programs. While our program costs may not significantly impact your bottom line, we understand that our results do, and we are passionate about helping you produce reliable, safe, and cost-effective steam.  Successful boiler operation requires a total system approach to:

We can perform detailed system audits and diagnostics to prescribe the best chemical, equipment and service programs to maximize your boiler system performance and efficiency.  Through utilizing our innovative programs, we can help you achieve water and energy savings, asset preservation, and increased plant reliability and safety.

 

We also offer a number of Feedwater Treatment programs to help meet your needs.  Feedwater is water added to the boiler to replace evaporation and blowdown. 

 

Regardless of how the feedwater is prepared, a chemical treatment is needed in order to prevent potential problems downstream.  We provide a complete offering of mechanical and chemical programs, including:

  • Hot & cold lime softening
  • Filtration
  • Ion exchange softening
  • Dealkalization

No matter how well the water entering the boiler is prepared, an Internal Treatment program is needed to keep your boiler running at its best.  There are four major problems that can occur inside the boiler, including: Scale, Deposition, Corrosion and Carryover. 

 

These issues typically are not isolated.  For example, under-deposit corrosion can also occur from concentrating mechanisms beneath the scale or deposit layer.  Carryover of boiler water solids into the steam may result from high levels of corrosion products in the boiler.

 

We offer a full complement of treatment programs to protect your boiler and keep it running efficiently.  We also offer an array of supplemental programs to further enhance your system performance.  Some of our key program offerings include:

  • All Polymer
  • Phosphonate
  • Chelant
  • Residual Phosphate

Our Condensate Treatment programs can also help you save energy, water and water pretreatment costs by maximizing the amount and quality of condensate returned to the boiler as feedwater.

 

Condensate is condensed steam.  Since condensate is very pure water with relatively high heat content, it is ideal for boiler feedwater. If the condensate is not properly treated, a number of contaminants could be introduced into the boiler and cause problems.  We can help you address these issues, and we also offer a full compliment of volatile, filming and blended corrosion inhibitors.
