Deep Injection Well Disposal of Desalination Concentrate at Inland Sites: Opportunities and Challenges
Economical and environmentally sound disposal of desalination concentrate can be the critical feasibility issue for inland desalination projects where a surface water outfall is not possible. Deep well injection can […]
RO Concentrate Disposal in California by Groundwater Injection
This paper presents the groundwater quality and the decision process that led to the treatment solution that was optimal for the client that deviated substantially from that listed in the […]
Not “Rolling the Dice”: A structured approach to starting up two large MBR facilities in the Las Vegas basin
Two large BNR MBR facilities were commissioned in the City of Henderson (Henderson SWRF) and the City of North Las Vegas (CNLV WRF) in the summer of 2011. In both […]
15,000 hours of Membrane Operational Experience: City of San Diego Advanced Water Purification Facility
Data generated from the City of San Diego Advanced Water Purification (AWP) demonstration project was used to support the City?s proposal for conditional regulatory approval and estimate of capital, operational […]
Draw Solution Induced Scaling during Ammonia-Carbon Dioxide Forward Osmosis Desalination
Forward osmosis (FO), an osmotic-driven membrane process, has been gaining attention for being a low-energy alternative for several applications usually performed by pressure-driven membranes, such as reverse osmosis (RO) and […]
Challenge Testing Osmotic Pre-treatment for Desalination
A desalination system comprising of two purification stages was developed: (1) a low-pressure forward osmosis pre-treatment stage that eliminates foulants from the feed water followed by (2) a high-pressure high-permeability […]
Surface Water Treatment with Ultrafiltration: Algae Blooms Operational Challenges
This study reports on the application of ultrafiltration (UF) to treat a water source that is subject to algae blooms, with data that demonstrates how the membranes may best be […]
Impact of Naturally Occurring DOM, Colloids, and Cation Interactions on Nanofiltration of Pharmaceutically Active and Endocrine Disrupting Compounds
The occurrence, fate and ecotoxicology of emerging organic micropollutants including pharmaceutically active compounds (PhACs), endocrine disrupting compounds (EDCs), and personal care products (PCPs) have been of interest in recent years. […]
Biological Pre-treatment for RO membranes – 10 Years and Counting
The intent of the paper is to provide an overall picture demonstrating the success of a biological filtration process, over the past eleven years, as a proven application for pretreating […]
