Bio-Fouling Control with Direct Coupled UF Pre-Treatment
This paper examines the experience of using submerged ultrafiltration (UF) for seawater desalination with reverse osmosis (SWRO) pretreatment for the GE Power and Water plant at Yuhuan in China and […]
UF-RO with Novel Pretreatment for a 15 mgd Water Supply Project
The Donna Bay Estuarine System located near Sarasota Florida was identified as a potential source of potable water. This project developed a treatment train comprised biological roughing filter for taste […]
An Evaluation of the Impacts to Membrane Filtration under the Influence of TOC, MIB, and Geosmin
The paper and presentation is of interest to utilities that are challenged by total organic carbon (TOC), Geosmin, and MIB in their source water and are considering the use of […]
Features of New PTFE-Made Microfiltration Hollow Fiber Membrane Module and Its Application for Oil and Gas Wastewater Treatment
Large amounts of wastewater are generated by some processes used to extract underground crude oil. A PTFE hollow fiber MF/UF membrane offers a reliable method of treating this wastewater and […]
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 […]
UF/NF Treatment of Organic Laden Wastewater in Industrial Pulp and Paper Wastewater
A nanofiltration membrane was successful in removing color ina highly colored wastewater from a pulp and paper plant. Initial lab trials with this color removal NF membrane and plant wastewater […]
Improving the Performance of UF Membrane Processes Using Electropositive Filtration to Polish Backwash Water
This paper and presentation cover results on the ability of an electropositive filter to remove organic and inorganic debris (nanoparticles, silica colloids, humic acid, and polysaccharides) from ultrafiltration (UF) filtrate […]
Performance and Advantages of Open Channel Feed Spacer RO Elements
The feed spacer on a spiral wound RO membrane is intended to develop for vortexes for prevention of localized salt concentrations to reduce scaling and generous openings to minimize fouling. […]
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 […]
Managing Organic Fouling and Arsenic at a Direct Membrane Filtration Plant Using Aluminum Chlorohydrate (ACH)
This paper presents the results from the full-scale testing of aluminum chlorohydrate (ACH) that is underway and describe lessons learned relevant to facilities that face similar challenges associated with variable […]
