The Process and Water Quality Specialists
Shane Trussell recently accompanied Cari Dale, the Water Utilities Director at the City of Oceanside, to co-present their IPR and Pathogen Removal Study at the White House Water Summit on March 22. This award is a great honor for Oceanside and Trussell Tech, reflecting our commitment to promoting sustainable water practices. The Water Summit coincided with World Water Day and featured panel discussions and invited speakers from the public and private sectors to raise awareness of priority water issues in the United States, and to catalyze ideas and actions to help build a sustainable and secure water future.
A Youtube link to the recorded meeting can be found here.
Trussell Tech is proud to be a part of an NWRI Independent advisory panel that worked with WateReuse Foundation, the American Water Works Association, and the Water Environment Federation to develop the recently-released Framework for Direct Potable Reuse. The guidance document is the first of its kind with the purpose of helping utilities develop guidelines for safely converting wastewater into municipal drinking water through the emerging practice of direct potable reuse (DPR).
Members of the panel included panel chair Dr. George Tchobanoglous of the University of California, Davis; Dr. Joseph Cotruvo of Joseph Cotruvo & Associates; environmental engineering consultant Dr. James Crook; Dr. Ellen McDonald of Alan Plummer Associates; Dr. Adam Olivieri of EOA, Inc.; Andrew Salveson of Carollo Engineers; and Dr. R. Shane Trussell.

We are pleased to announce the publication of a Trussell Tech article, "Technical Note: Calculation of the Langelier Index at High pH," in the March issue of the Journal of American Water Works Association (AWWA). The article describes an error that Trussell Tech identified in the Standard Methods' (SM) calculation of the Langelier Saturation Index (LSI), and provides equations for correcting the error. Trussell Tech has updated its corrosion model and its blending worksheet to use the corrected calculation. Trussell Tech has also taken this opportunity to simplify the corrosion model and update the mineral analysis model and the blending worksheet. Total dissolved solids (TDS), rather than a complete mineral analysis, is now used to estimate ionic strength in the corrosion model, which simplifies the water quality analyses that are required to use the model. John Kenny is chairing the AWWA SM Joint Task Group on updating the LSI calculation method.
Trussell Tech's David Hokanson and Rhodes Trussell are the authors of the newly-published "A photolysis coefficient for characterizing the response of aqueous constituents to photolysis" in the March issue of Frontiers of Environmental Science & Engineering. Prof. Ke Li from the University of Georgia is also a co-author. The article advances UV photolysis through development of a novel photolysis coefficient to evaluate UV processes for inactivation of microorganisms and treatment of inorganics and organics. The paper is relevant to the application of UV technologies and and UV AOPs for drinking water treatment and water reuse applications. The article proof can be found here.
We are excited to announce the publication of Trussell Tech’s article on potable reuse safety, “Achieving Reliability in Potable Reuse: The Four Rs,” in the Journal of the American Water Works Association.
The Ways of Water
The Ways of Water, presented by the WaterReuse Foundation, is an overview of the many human interventions in the water cycle. It looks at the benefits of some key water provision options including Direct Potable Reuse (DPR). The animation is an easy-to-understand presentation of the urban water cycle and water purification.
Trussell Tech was proud to participate in the groundbreaking at Padre Dam Municipal Water District's Advanced Water Purification Demonstration Project. Trussell Tech is the Program Manager for the AWP Demo Project, whose goal is to use advanced water purification technologies to potentially diversify East County’s water supply and reduce dependency on imported water. The project is scheduled to begin operation in March 2015.
