Common System Design Problems
This presentation on membrane system design is from a preconference workshop in 2014 that discussed optimization of membrane plant performance and troubleshooting. Different aspects of plant design including pretreatment, skid […]
Case Study for Irvine Ranch Water District – Fouling of NF Membranes
This paper is a case study of the Irvine Ranch Water District (IRWD) in Orange County, California that provides potable water (local groundwater and imported), wastewater treatment for the production […]
Advancing Reverse Osmosis Membrane Performance in a Water Reuse Application – A Collaborative Approach
In an advanced water reuse application, reverse osmosis (RO) technology serves a critical role. This paper reviews the benefits of operating high performance RO membranes, and the obstacles associated with […]
Obtainment of Polymeric Membranes from Sugarcane Bagasse
Cellulose acetate (CA) membranes are generally produced from wood or cotton cellulose. Cellulose acetate can be produced from sugarcane bagasse which is a lower cost alternative. Dichloromethane was used as […]
Reliability, Redundancy, & Long-Term Operations: Designing a Flexible Integrated Membrane Plant
Reliability is a major consideration in a treatment system supplying boiler feed and cooling tower makeup for a refinery. Many redundant components and operating features were incorporated in the water […]
From Industrial Wastewater to Ultrapure Water Using Membrane Technologies
A large steel manufacturing plant uses a significant amount of water for the steelmaking process and boiler feed. Treating the wastewater generated from the steelmaking process for reuse within the […]
Flexible Desalination Systems for Variable Salinity Sources
Variable salinity desalination applications are becoming more abundant. The Expeditionary Unit Water Purifier Generation 1 was used to evaluate the practical aspects of converting a singlestage seawater system with energy […]
Achieving and Verifying Ultra-Low Phosphorus for Wastewater Discharge or Reuse
This paper gives the findings of the pilot study with regards to the sequencing batch reactor (SBR), cloth media filtration (CMF), and ultrafiltration (UF) parameters required to obtain ultra-low phosphorus […]
Redefining the Economics of High Solute Water Treatment
The purposes of this paper are to compare forward osmosis (FO) to best available technologies for treating high salinity feed waters and waters that limit the capabilities of reverse osmosis […]
