Case Study: Reverse Osmosis Groundwater Treatment Expansion and Retrofit at the City of Goodyear’s Bullard Water Campus
The Well #26 and Raw Water Transmission Main project is being undertaken to provide needed capacity, redundancy and flexibility for the City of Goodyear’s water distribution system. The project scope […]
Automated Conductivity Profiling of Reverse Osmosis Units for Integrity Verification
Recent activity in the potable reuse field incorporates reverse osmosis (RO) processes as a requirement to provide pathogen removal and a reduction of other compounds. California has implemented the 12-10-10 […]
Treating Variable TDS Feed Water: Cost-Effective Existing System Modification and Upgrade
The Collier County North County Regional Water Treatment Plant (NCRWTP) is a 20-mgd facility including a 12-mgd nanofiltration (NF) system and an 8-mgd brackish water reverse osmosis (BWRO) system. The […]
PFAs Rejection by NF and RO as a Function of Speciation, Membrane Characteristics and Recovery
Academic research on the use of flat-sheet coupons of NF and RO membranes at bench scale for removal of PFAS dates back to 2006. Tang et. al (2006) investigated removal […]
Optimizing Membrane Filtration Systems Through the Application of Digital Twins
This paper provides two project case studies, City of Spokane and Gwinnett County, where dynamic simulation was used to assist with the design and optimization of membrane facilities. The City […]
Pilot Study Results of New High Surface Area UF Module at Clifton Water District
The goal of membrane development in water treatment has historically been to treat more water or wastewater in a smaller footprint. Pioneering Reverse Osmosis (RO) membrane manufacturers originally started out […]
What is a Contractor’s Role in an Alternative Delivery Project Mebrane Selection?
Water and wastewater projects that incorporate complex systems or anchor process equipment can quickly face schedule and cost delays during the design and construction. This complexity lends itself well to […]
Energy Reduction in Ceramic Microfiltration using Carbon-Dioxide-Enhanced Backwash
Supersaturated carbon dioxide solution was applied to backwash ceramic membranes. Three types of feed water were employed with the filtration of three membranes with different serving time. CO2 backwash had […]
Comparison Between Pulse Flow Reverse Osmosis (PFRO™) and Standard RO
Wastewater reuse, together with zero or near zero liquid discharge, has been a growing trend due to the requirement of sustainable water management mandated by tightening discharge regulations. A lot […]
