New Trends in Membrane Technology – February 2016 edition: Membranes have emerged as a significant innovation for treatment. Membrane treatment for wastewater can be tracked down over three decades ago. However past decade witnessed a rapid increase in the volume of wastewater that is treated with membranes to remarkably high quality standards, typically for reuse purposes. Indeed, today more municipal wastewater treatment facilities are using membrane technologies than ever, and this number is on the rise as the technology offers unparalleled capability in meeting rigorous requirements. Membranes may be an option when they enable the removal of contaminants that other technologies cannot. They are also more economical than other alternatives, or require much less land area than competing technologies, since they may replace several unit treatment processes with a single one. For wastewater treatment applications, membranes are currently being used as a tertiary advanced treatment for the removal of dissolved species; organic compounds; phosphorus; nitrogen species; colloidal and suspended solids; and human pathogens, including bacteria, protozoan cysts, and viruses. Technological developments offer increased system efficiency, higher quality effluent and alternative water sources and help end users mitigate regional water quality and supply challenges. RO, MF, UF and MBR technologies have proven to be an effective and reliable options for the treatment of wastewater and the reuse of effluent waters to augment scarce resources. Trends in membrane technologies will have an impact on salinity issues, as a result of increased membrane use and associated concentrated discharge. Membrane technology improvements and increasing cost effectiveness, including higher efficiency in membrane systems, reduced energy and membrane costs, and the development of selective and low fouling membranes could result in an increase in the use of membrane technologies. The biggest technical challenge with the use of membranes for wastewater treatment is the high potential for fouling. Membrane fouling, which can be caused by colloids, soluble organic compounds, and microorganisms that are typically not well removed with conventional pretreatment methods, increases feed pressure and requires frequent membrane cleaning. This leads to reduced efficiency and a shorter membrane life. Other technical barriers may include the complexity and expense of the concentrate (residuals) disposal from high-pressure membranes. Treating wastewater with membranes is on the rise. It is not only a viable option, but often a smart one when considering plant upgrades and capacity expansion. Our February issues will be focusing on the “New Trends in Membrane Technology”.
