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.
Energy Reduction at a Municipal Water Plant in Florida using New RO/NF Membrane Technology
After 13 years of operation at Palm Beach County, FL, the nanofiltration elements were replaced with a hybrid nano/RO system that resulted in an energy savings of 30% while maintaining […]
Comparison between performance of reverse osmosis and nano-filtration membranes in the process of desalination of brackish water
Comparison of results using either nanofiltration or brackish elements on a brackish groundwater source. This was a bench scale study.
Design and Procurement of a 12 MGD Open Platform UF Membrane System
Replacement of media filters with an open platform UF system. Discusses specification preparation, procurement details and interchangability of UF modules for future replacements.
Critical Considerations for the Advancement of Non-Proprietary, Flexible, and Universal MF/UF Systems
Considerations that must be addressed when bidding an open platform UF system
High recovery desalination with enhanced evaporation: Achieving ZLD sustainably
This paper evaluates the combination of enhanced recovery and evaporation processes for technical and economic feasibility, commenting on the advantages and disadvantages. The Zero Discharge Desalination (ZDD) process demonstrated in […]
Zero Liquid Discharge (ZLD) Process Utilizes UF to Achieve 98.5% Recovery
An extended mixing zone was no longer permitted. City had to implement a ZLD system which also allows beneficial use of the residual solids.
Role of pre-RO (cartridge) filtration in MBR-RO Systems
Pilot study of an MBR/RO system studying the effectiveness of various pretreatment methods.
SFMP + MBR = 3Q CHANGING THE CALCULUS OF WWT & REUSE
Effective use of stormflow management process + MBR to overcome previous MBR limitations.
Assessing Long-Term Performance of Membranes via Membrane Autopsy
Autopsy studies of MF/UF membranes to evaluate wear and tear and the possibility of integrity failures after long use.
