Effects of Sodium Hypochlorite Ageing on the Cleaning Requirements of PVDF Based Membrane
PVDF based UF/MF membranes are susceptible to fouling and are generally cleaned using a chlorine-based solution. Exposer to sodium hypochlorite removes a portion of the hydrophilic additives from the membrane […]
Singapore’s 3rd and 4th Taps – Overview of Newater and Seawater Desalination Plants
This paper discusses the procurement methods used and cost of the water from Singapore?s seawater desalination and reuse supplies. The cost of the water either desalinated seawater or NEWater is […]
Maximizing Water Resources: A 99% Efficient Membrane Treatment System
This paper and presentation provide an overview of the following: history of project and why 99% efficient is cost effective; configuration of the new treatment system; discussions with regulatory agencies […]
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 […]
Sheyenne River Unique Water Quality Challenges: A Comparative Pilot Study of Three MF/UF Membranes
The City of Fargo Water Treatment Plant (WTP) recently piloted GE submerged ZeeWeed 1000, Siemens encased MemCor L20N, and Pall encased UNA-620A membranes for its new 15 million gallons per […]
Spiral-Wound Membrane Performance Monitoring for System Optimization
Spiral-wound water purification elements (e.g. reverse osmosis, nanofiltration) were developedin the 1960s in response to increasing water demand. Since then, the need for pure water has evolved to include not […]
Pervaporation Desalination of High Salinity Oil and Gas Produced Waters
This presentation will cover our work to date in developing and testing new membrane materials for use in pervaporation desalination applications. Our work has specifically targeted high TDS produced waters […]
Advancements in Desalination Technologies
As the gap between world-wide water supply and demand widens and the availability of fresh water supplies dwindle, neew technologies are urgently needed to treat impaired waters in a sustainable […]
Low Pressure Membrane Piloting/Testing
This presentation from a preconference workshop in 2014 for Back to Basics on membrane technology discusses low pressure pilot plants and testing. Why to pilot, when to pilot, what to […]
From Cradle to Start-Up – A Story of a “Greenfield” Microfiltration Plant in Northern Virginia
The paper in general provides an in-depth case study of a greenfield microfiltration plant, summarizing issues from conceptual design to construction. The paper will be beneficial for utilities that are […]
