CPM gladly sponsored and participated in this year’s Puerto Rico Water and Environmental Association Annual Conference & Technical Exhibition 2022, an event held on November 2-3, 2022, at the Hyatt Regency Grande Reserve.   Special thanks to our colleague, Luis Meléndez Fox, Senior Project Manager, for his active participation as speaker for a thoughtful presentation on the Alternatives for Controlling Hydrogen Sulfide Odor and Corrosion Issues in Wastewater Treatment Systems.
