Efficient, safe, and reliable boiler water treatment

Corrosion, scaling, and fouling will severely reduce the efficiency of boiler operations and compromise the associated performance of all the systems connected to the water and steam circuits. When these conditions impede heat transfer in the boilers, operational costs quickly grow from increased fuel usage for the same production rates. Even small, thin layers of deposition incur increased costs and damage.

Good site monitoring should detect the increased inefficiencies to react with corrective actions.

To prevent the risks, Veolia’s Hydrex chemical solutions offer specific boiler water treatment programs leveraging the Hydrex 1000 Series. A market-approved range of high-performance chemicals, it includes:

Low, medium, and high-pressure boiler chemicals for internal treatment programs.
Oxygen scavengers for feedwater treatment.
Scaling and corrosion inhibitors.
Dispersants designed to condition sludge for easier removal.
Neutralizing amines for boiler feedwater treatment to raise the condensate pH and protect the return line.
Antifoam agents.
Streamline chemicals.

Maximize the performance of your cooling water assets

In cooling systems, corrosion problems are generally linked to aggressive water or low pH. Mineral fouling is caused by scaling water and/or high skin temperatures (heat exchangers), while organic fouling is generated by factors such as bacterial growth and suspended matter linked to atmospheric dust or process leaks.

To cover all these aspects and maximize cooling tower performance, our Hydrex chemical solutions implement specific cooling water treatment programs leveraging the Hydrex 2000 and Hydrex 7000 Series. Selected by our on-site expert teams according to the specific operating conditions of your cooling systems, they include:

Mineral scale inhibitors include phosphorus- and non-phosphorus-based products.

High-performance polymeric dispersants.
Specialty metal corrosion inhibitors for both anodic and cathodic protection throughout the cooling water systems.
Biodispersants to aid in removing biofouling.
Non-oxidizing and oxidizing biocides.
A wide selection of cooling water system cleaning agents.

Conclusion

Every project begins with understanding your water and wastewater challenges and goals. During this step of our process, we look to collect the necessary information about your water, require effluent specifications, perform lab studies, survey site conditions, and perform sampling campaigns for treatment.
