HBC Engineering Company | 90 <br />Puerto Rico Aqueduct and Sewer Authority (PRASA), PER for the Elimination of the Ciales, Morovis, and <br />Uniban Wastewater Treatment Plants <br />As Project Engineer, Yissell supported the Preliminary Engineering Report evaluating alternatives to connect <br />the Ciales, Morovis, and Uniban WWTP flows to the Vega Baja WWTP. Her work covered pump station design <br />recommendations, force and gravity main route evaluations, head loss analysis, and environmental and <br />constructability assessments, including evaluation of intermediate pump stations to optimize flow. <br />Location: Rio Grande, Puerto Rico, FL. Dates: Ongoing. Reference: Jose A. Rodriguez, PE, 787-641-6800, jarodriguez@ <br />csagroup.com. <br />* Florida International University (FIU), Design of an Ion Exchange Process for the Removal of PFAS in the <br />Water Supply at Broward County <br />As Task Manager, Yissell contributed to the design of an ion exchange process to reduce 83 parts per trillion <br />of PFAS for an existing potable water treatment plant. She developed engineering solutions to ensure removal <br />efficiency, scalability to the plant's current and maximum permitted flow rates, and compatibility with existing <br />facility processes. <br />Location: Broward County, FL. Dates: 08/2022-12/2022.

Dates: 8/2022-12/2022. Reference: Walter Tang, (305) 348-3046, tangz@fiu.edu. <br />* Florida International University (FIU), Design of an Attached Growth and Combined Biological Treatment <br />Process for a Wastewater Treatment Plant <br />As Project Manager and Lead Designer, Yissell contributed to design alternatives based on attached growth and <br />combined biological treatment processes to improve an existing plant's activated sludge system, providing Moving <br />Bed Biological Reactor (MBBR) and Membrane Bioreactor (MBR) options. She also addressed removal of Per- and <br />Polyfluoroalkyl Substances (PFAS) from wastewater to help protect the environment and public health. <br />Location: Miami-Dade County, FL.
