**Contaminants found in the piping, tanks and other wetted surfaces of a water system can cause production downtimes for cleaning operation, health and safety risk for operators and increased costs. The HydrexⓇ 5000 Series is a range of chemicals specifically formulated for the optimal industrial cleaning and maintenance of water treatment units.** [CONTACT US TO FIND OUT HOW WE CAN HELP](https://www.veoliawatertechnologies.com/en/contact-web2lead) ## Increase productivity with deposit-free water assets **To operate efficiently and cost-effectively**, a water system must be **free of any deposits** that could reduce its performance. Removing these deposits also **ensures the sustainable protection of cleaned surfaces**. Applicable for most water and industrial processes, our **Hydrex 5000 Series helps recover the properties of a clean system** such as intended by the initial thermal exchange design. Doing so also **increases flow rates** and o**ptimizes operating costs**. The high-performance, market-approved products include: **Maintenance and cleaning products:** - Antiscalants for steel surface. - Carbonate, iron oxide deposits. - Biological deposits. - Acidic cleaners. - Alkaline cleaners. - Mixed applications. - Bio-sourced cleaners.  **Deposit removal:** - Resin cleaning products. - Scale removers. - Degreasing agents. - Passivators. - Antifoams. - Surfactants. As the conditions (type of foulants, system metallurgy, waste disposal concerns of the system to be cleaned, etc.) differ at each site, on-site support service provided by a Veolia expert can help select the most suitable formulations and build specific treatment strategies.  ## Features and benefits  **Effective removal of most deposits for all water treatment systems.**  **Enhanced formulations that contribute to a longer metal corrosion protection film level than just during a cleaning.**  **Chemicals to be coupled with [equipment](/en/services/equipment-chemical-water-treatment-solutions "Equipment for chemical water treatment solutions "), [digital services](/en/services/hubgrade-hydrex-chemical-solutions "Hubgrade for Hydrex® chemical solutions"), real-time [monitoring](/en/services/hydrex-controllers "HydrexⓇ Controllers") tools and on-site service for complete Hydrex water treatment programs.**  **Compliant, reliable, safe and cost-effective operation.**  **Focus on water, energy and chemical savings for a reduced environmental footprint.** ## Resources [PDF Hydrex Maintenance & cleaning chemicals (283.52 KB) ](/sites/g/files/dvc3326/files/document/2024/03/DS%20WTC%20HYDREX%205000%20Series%20for%20Maintenance%20112023%20EN.pdf) ## Applications  Condensate recovery ### Condensate recovery [  ](/applications/veolia-water-technologies-supplies-world-drinking-water)[Drinking water](/applications/veolia-water-technologies-supplies-world-drinking-water) ### [Drinking water](/applications/veolia-water-technologies-supplies-world-drinking-water) [  ](/applications/industrial-wastewater-treatment)[Industrial wastewater treatment](/applications/industrial-wastewater-treatment) ### [Industrial wastewater treatment](/applications/industrial-wastewater-treatment) [  ](/expertise/applications/process-water-0)[Process water](/expertise/applications/process-water-0) ### [Process water](/expertise/applications/process-water-0) [  ](/applications/utility-feed-water)[Utility feedwater](/applications/utility-feed-water) ### [Utility feedwater](/applications/utility-feed-water)  Water pretreatment ### Water pretreatment [go back to water treatment chemical programs overview](/services/water-treatment-chemical-programs)
