Water Softening with Ultrafiltration for Surface Waters: Keys to Successful Membrane Piloting

Project 7 Water Authority (P7WA) evaluated pellet softening as pretreatment for ultrafiltration (UF) for a surface water with low TOC but very high hardness at the pilot scale. In addition to demonstrating a successful membrane treatment process, this study provides an example of key piloting steps, from identifying project drivers and defining testable research questions […]

Implementation of Membrane Gravity Filtration (MGF)

Membrane Gravity Filtration (MGF) is an application for retrofitting gravity media filters using ultrafiltration membranes. It combines the simple operation of a media filter with the superior treated water quality of a UF membrane. MGF is best suited for applications where customers need better turbidity removal, a barrier to pathogens, or need to significantly increase […]

Lessons learned from design and operation of Membrane Bioreactor (MBR) Facilities

This presentation presents the progress and applications of MBRs which provides the benefit of biological treatment process in a compact footprint and solids liquid separation for a high-quality effluent. In this paper, lessons learned and challenges from design and operation of MBR plants are presented. MBRs provide the pretreatment required for other treatment technologies such […]

Membrane Bioreactor (MBR) Troubleshooting

An overview of several typical issues that plague MBR systems, and how to troubleshoot them. The presentation will also include a quick overview of common design issues we run into that can contribute to operational issues.
