Process Interrupted: Using BOR Funded Desalination Research to Evaluate an Innovative Process Train to Halt the Salt Accumulation in a Sewer-shed from Cooling Towers while also Promoting a Circular Economy.
- Eric Dole, PE, PSAP, Garver USA
- Michael Watts, PhD, Garver USA
- Yuliana Porras-Mendoza, US Bureau of Reclamation
The Southwest U.S. is challenged by freshwater scarcity and salt accumulation in its watersheds. A significant contributor to salt loading in urban sewer-sheds are the many industrial and commercial cooling towers that dot the landscape. These towers are very effective at cooling in arid environments; however, they use scarce freshwater resources to absorb heat through evaporation while accumulating the salts and minerals that must be discharged as blowdown.
Garver was selected by the Bureau of Reclamation’s Desalination and Water Purification Research Program Pitch to Pilot to research a novel treatment train that will reduce the amount of salt discharged from industrial cooling tower blowdown.
Garver’s zero liquid discharge, membrane desalination treatment train is estimated to remove more than two tons of salt from the 600 ton cooling tower blowdown and saved approximately 200,000 gallons of make-up water from the potable water supply over the eight-month field-testing portion of the pilot study. The reduction of salt discharged to the sewer will benefit the local wastewater treatment plants and the local watershed, while also improving the water quality of the cooling towers with a low energy intensity treatment train.
This presentation will address the BOR Desalination Pitch to Pilot Program, the thought process behind the EC, UF, GAC, RO with VAED concentrate management treatment train and report on commissioning efforts to date.
Eric is a senior project manager at Garver where he serves as the Water and Energy Practice Leader. He specializes in delivering sustainable infrastructure solutions through optimized hydraulic systems and optimized treatment processes. In 2019, Eric was selected for the Water Research Foundation’s 12-person Energy Advisory Committee where he advises the group on energy efficiency and process optimization projects.
Eric was one of the world’s first water professionals to be certified as a Pump Systems Assessment Professional (PSAP) through the Hydraulics Institute, which allows him to set the standard for pump systems assessments and optimization techniques, leading to energy efficient and reliable systems. His process mechanical expertise can be seen in his patented designs for two zero liquid discharge brine management systems, of which one was awarded the 2011 AZ Water Reuse Project of the Year Award and the other was selected for RO concentrate treatment in the Bureau of Reclamation Desalination Pitch to Pilot Research Project that started in September 2020 and is scheduled for commissioning in May 2021.
Dr. Michael Watts is a reclaimed water strategist, and the water reuse practice leader with Garver. His experience includes water quality analysis, water reclamation, and publication of peer-reviewed water research. In addition, he has developed and implemented bench- and pilot-scale treatment evaluations, and assisted utilities with compliance with water quality and water reuse regulations. Dr. Watts joined Garver in 2013.

Learn how digital platforms that include artificial intelligence and machine learning can be used to improve asset management strategies and operational efficiencies.
11:00 am – 12:00 pm PT | 2:00 pm – 3:00 pm ET
WateReuse Members: Free
In this webcast, our presenters will introduce how digital platforms that include artificial intelligence (AI) and machine learning (ML) can be used to improve asset management strategies and operational efficiencies, as well as enhance source control, validate unit process performance, predict product water quality and make sound decisions for assessing suitability of product water for human consumption.
The data collected from pilot and full-scale potable reuse treatment trains have been used to develop artificial neuron networks as part of an ML platform. The platform clearly demonstrates that ML can be used to predict, for example, the product water total organic carbon (TOC) concentration of a pilot advanced treatment facility and the specific fluxes on the third stage of a full-scale advanced treatment facility as the feed quality and operating conditions are changed.
The methodology used and model outputs will be discussed during the webcast. The presenters will also examine how we can couple AI/ML concepts with the Internet of Things (IoT) and next generation of the SCADA systems to operate and maintain assets efficiently while significantly enhancing public and regulatory confidence in potable reuse projects.
