Post Treatment Challenges of Replacing Lime Softening with Nanofiltration
The purpose of this paper to present the findings of a research study developed by the Town of Jupiter and the University of Central Florida (UCF). Research was conducted to […]
High-Recovery Electrodialysis Reversal for the Desalination of Inland Brackish Waters
Due to prohibitively high cost of inland desalination, there has been a surge of interest into emerging technologies and techniques for recovery enhancement and concentration minimization. EDR has been identified […]
Water Chemistry and Pretreatment Chemicals
This presentation from a preconference workshop in 2014 for Back to Basics on membrane technology discusses pretreatment chemistry for microfiltration, ultrafiltration, nanofiltration and reverse osmosis. Water chemistry is presented and […]
RO Energy Optimization Project Case Study
This case study of the upgrades to the Bonita Springs Brackish water membrane plant was given at a Preconference Workshop on optimizing membrane plant performance in 2014. Energy recovery options, […]
Review of the Integrated Performance of the Fort Thompson WTP
This paper and presentation review the performance of one of the first large-scale membrane systems using Dow ultrafiltration (UF) membranes after 18 months of operation. Performance in terms of membrane […]
Low Chemical Usage in Membrane Operations
The Oden Water Association installed an open platform style microfiltration treatment system to allow competitive bidding of replacement ultrafiltration membranes. The open platform style allows flexibility in operation in backwashing, […]
No Cause For Alarm? How What is Not Covered in the MFGM Can Impact MF/UF Plant Operations and Control System Set Points
This paper and associated presentation explores these areas of regulatory discretion under the Long-Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR) membrane regulatory framework, discussing the impact of different approaches […]
Evaluation of Treatment Performance and Membrane Fouling Propensity of Different Pore-Sized Ceram
Anaerobic membrane bioreactors offer a wastewater treatment process that uses less energy and space than an aerobic MBR. The anaerobic process leads to more frequent fouling and therefore more frequent […]
New Remineralization Process Using Micronized Calcite as a Sustainable Alternative to the Lime-Dosing System
Desalinated and naturally soft water is corrosive because of its low pH value and lack of minerals, and therefore requires post-treatment for water stabilization and corrosion control. Conventional water remineralization […]
Piloting Alternative Technologies for Indirect Potable Reuse in Florida
As growing demand taxes existing drinking water supplies and rising wastewater effluent standards lead to more advanced wastewater treatment, planned indirect potable reuse is becoming a feasible scenario for more […]
