A Study of Iron Redox Reactions and Associated Irreversible Damage Within Reverse Osmosis Systems
Case studies on reverse osmosis systems experiencing unexplained rejection loss with deep well water sources. Comparisons are assessed between sites with similar water sources that run smoothly and ones that […]
Energy Savings by Design for New Advanced Treatment Plant for Groundwater Recharge in Southern California
The Water Replenishment District (WRD) is constructing a new 13,000 acre-feet per year Advanced Water Treatment Facility (AWTF) in the city of Pico Rivera. The AWTF is part of an […]
Twin Turbochargers Provide High Permeate Recovery at Low Net Energy Consumption and Low Capital Cost in Megascale SWRO Systems
This study will compare conventional SWRO systems operating at 40-45% recovery utilizing currently available energy recovery devices with the twin turbocharger design operating at about 60% recovery. Also, the impact […]
Results of 2017 Survey of US Municipal Desalination Facilities
This paper presents results from the latest survey conducted in 2017 and funded by the Bureau of Reclamation.
A Novel Approach for Concentrate Minimization: Phase II
This presentation follows up from a previous study where a two-pass nanofiltration/reverse osmosis (NF/RO) system was used to selectively remove sodium chloride and reduce concentrate disposal costs. The current study, […]
That’s a Good-looking 4th Stage on Your RO System
This presentation uses operations at an existing 10 mgd inland desalter facility (with an additional 10 mgd expansion currently being designed) and analysis from a four-stage pilot system to outline […]
Treatment of Reverse Osmosis Brine Through Chemistry
This presentation is about how to use the chemistry we know in brine water to solve scale build-up attributable to long disposal lines, inconsistent flows, and the introduction of air. […]
