Two 2” galvanized supply lines feeding their production process were almost completely plugged, preventing water flow to the plant. The client was planning to perform a $1,000,000 CAPEX project to replace the failing infrastructure. Veolia was contacted by the client to see if there was a chemical services program that could mitigate the issue. **Solution:** After performing a comprehensive facility audit, a pilot test on sacrificial sections of the corroded and plugged piping, Veolia found that a 20% solution of Hydrex 2978 which was circulated through the piping for approximately 30 hours was an effective solution to restore the pipe's condition. After the pilot, a full-scale program was installed at the customer site. **Results:** - Heat exchanger water flow and efficiency restored - $1M Capital equipment replacement eliminated - Long-Term Prevention of Corrosion and Scaling The Hydrex™ Product Line ### The Hydrex™ Product Line **Boiler Water Treatment Products** ***Hydrex 1000 Series*** Ideal for boiler and heating applications in low, medium and high pressure boilers. **This product series includes:** - Scale inhibitors - Corrosion inhibitors - Antifoams - Oxygen scavengers - Steam and condensate treatment - Green products **Cooling Water Treatment Products** ***Hydrex 2000 Series*** Improves the efficiency and reliability in open, closed and once-through cooling water systems **This product series includes:** - Scale inhibitors - Corrosion inhibitors - Dispersants - Antifoulants **Potable Water Treatment Products** ***Hydrex 3000 Series*** Approved for potable water applications. **This product series includes:** - Flocculants - Coagulants - Green chemistry - GRAS/NSF approved products **Membrane Treatment Products** ***Hydrex 4000 Series*** Ideal for Reverse Osmosis, Nanofiltration, Ultrafiltration and Microfiltration treatment systems. **This product series includes:** - Membrane antiscalants - Biocides - Chlorine removal chemicals - Cleaners - Antifoulants/Dispersants **Wastewater Treatment Products** ***Hydrex 6000 Series*** Used in water purification, industrial process and both municipal & industrial wastewater treatment systems. **This product series includes:** - Coagulants - Demulsifiers - Dewatering Aids - Flocculants - Antifoaming agents - Odor Control - Metals Removal - Green chemistry **Biocides** ***Hydrex 7000 Series*** Used to control the growth of bacteria, fungi and algae in cooling water, process water, recycled water and wastewater systems. **This product series includes:** - Oxidizing and nonoxidizing products - Cooling and Process use registrations - Legionella prevention - Broad spectrum of products **Industrial Application Products** ***Hydrex 8000 Series*** Intended for industrial processing applications. **This product series includes:** - Chain lubricants - Food and beverage processing - Biofuels processing - Upstream oil & gas processing - C.I.P. cleaners - Mining processing **Other Chemical Applications** ***Hydrex 9000 Series*** Solutions for each specific requirement in terms of chemical water conditioning including custom-made formulations. **This product series includes:** - Thermal desalination - Dust control - Miscellaneous and bulk chemicals Featured Resources ![Hydrex Chemical Solutions](/sites/g/files/dvc3601/files/styles/media/public/image/2021/11/Hydrex%20Brochure%20Cover.PNG.webp?itok=9GAAT_N0) ### Other Related Resources - Article: [Water Audits Can Uncover Significant Operational Improvements at F&B Manufacturing Facilities](http://watertechnorthamerica.veolia.acsitefactory.com/en/publications/articles/water-audits-can-uncover-significant-operational-improvements-food-and "Water Audits Can Uncover Significant Operational Improvements at F&B Manufacturing Facilities") - Article: [Crafting H2O with Madtree Brewing](http://watertechnorthamerica.veolia.acsitefactory.com/en/publications/articles/crafting-h2o-madtree-brewing-cincinnati-ohio "Crafting H2O with Madtree Brewing") - Brochure:[ HydrexTM Corn Oil Additives Optimizing Corn Oil Yield & Quality](http://watertechnorthamerica.veolia.acsitefactory.com/sites/g/files/dvc3601/files/document/2020/07/60314-HydrexCornOilAdditiveBrochure-v6-5.pdf) [Download Brochure](https://www.veoliawatertech.com/sites/g/files/dvc3601/files/document/2021/11/210103_Hydrex_Brochure_v8-NA.pdf)
