Mr. Bruce Johnson is a wastewater technology fellow with CH2M and is currently serving as CH2M’s wastewater process design lead for its alternative delivery business as well as the global technology leader for wastewater process simulation.  As part of his work within CH2M he has been responsible for developing and implementing a wide range of innovative treatment approaches, including the development of the Post-Aerobic Digestion (PAD) process.

Mr. Johnson has been doing wastewater treatment design for over 25 years, the last 20 of which has been with CH2M.  He started out his career working in the technology group of Eimco (predecessor to Ovivo) where he worked on various biological and filtration technologies.  With CH2M, Mr. Johnson has worked in its industrial, design, and water business groups where he has held the roles of Industrial Process Practice Leader and Wastewater Process global technology leader.

He has been active outside of CH2M both in WEF and IWA.  Within WEF, he led the development of the new Nutrient Removal MOP, vice chaired the committee that developed the Wastewater Simulation MOP, and was a contributing author in MOP 8’s suspended growth chapter.  He also chaired the WEFTEC wastewater symposia committee, and was a founding member and past chair of WEF’s Modeling Experts Group of the Americas.  Within IWA, Mr. Johnson helped develop the wastewater treatment modelling seminar series (WWTmod) and is a past scientific chair.  He also was a founding member of the IWA Design and Operations Uncertainty Task Group, and is currently participating in the Physical Chemical Modelling Task Group.

In his career, Mr. Johnson has published many papers on a wide range of wastewater treatment subjects, and has been awarded four different patents based on his innovative approaches to wastewater treatment and design.
