Entex is proud to welcome Frank Jeffries to the team! Frank joined in August of 2025 as a Project Engineer, where he’ll contribute to process modeling, process design, and project execution.
Frank holds both a B.S. and M.S. in Biosystems Engineering from Clemson University. His academic and research background focused on biological process design and modeling—fueling his passion for wastewater treatment. In his master’s program, Frank conducted research quantifying the reaction kinetics of a novel anaerobic process that converts agricultural residues into hydrogen gas. He then used the results to build a dynamic process simulation model.
Frank also worked under the Municipal Engineer for Clemson, where he supported the University’s management of stormwater, potable water, and wastewater treatment systems. This blend of research and municipal experience provides a strong foundation that Frank is excited to bring to Entex. He is particularly enthusiastic about applying advanced treatment technologies to create a cleaner environment and more resilient future.

When asked what drew him to Entex, Frank shared:
“The team seemed really great from my early interactions. Definitely a big reason I was interested! After learning a little more about Entex, I have come to find our products to be a very simple yet effective application of fixed-film technologies.”
Outside the office, Frank spends his free time rock climbing, keeping aquariums, and producing music.
We’re excited to have him on board and can’t wait to see the impact he makes!
