Pilot Testing of SAT, NF, O3, BAC for Potable Reuse for Inland Applications
The City of Tucson AZ are planning for potable reuse using a municipal secondary wastewater effluent. The technologies piloted were Soil Aquifer Pretreatment (SAT), nanofiltration (NF), ozonation, Biological Activated Carbon […]
Membrane Facility Operations and Expansion – Transitions to Accommodate a Utility?s Needs
Pretreatment at a City of Fort Worth TX water treatment plant to a low pressure hollow fiber membrane system used ozone, clarification, and biological anthracite filters. Design, planning and operations […]
Coagulation Optimization: Pilot-Scale Analysis of UF Fouling and DBP Formation
The most widely applied pre-treatment to UF is coagulation, often to aggregate fractions of organic matter that cause fouling or those fractions that form disinfection by-products (DBPs) upon chlorination. Recent […]
Everything is Bigger in Texas: Implementation of the Country?s Largest High Recovery Inland Brackish Groundwater Desalination Facility

Chlorine Dioxide as Disinfectant for Pretreatment in Seawater Desalination Plants
Discusses how to prevent chlorine dioxide residuals from passing from the pretreatment step to the reverse osmosis elements which would damange the membranes. Case studies are all seawater desalination plants.
Optimization of subsurface intake designs for seawater desalination facilities
Subsurface intakes are increasingly used for raw water supply to seawater desalination facilities because of their reduced overall costs and environmental footprints. The technical challenge for using subsurface intakes lies […]
Water Reuse in Remote Work Camps
This paper discusses how remote work camps (semi-permanent accommodations located near resource exploration and extraction activities) are well suited for wastewater reuse and how to address the specific challenges that […]
Membrane Upgrades to Address Aging Water Treatment Infrastructure Challenges in a Small System
Deteriorating water treatment infrastructure and high levels of organics in the raw water created challenges for the Village of Hines Creek in satisfying ESRD?s more stringent treated water quality standards. […]
