Membrane Technology February 2013

The American Membrane Technology Assn. (AMTA) offers a number of opportunities to learn, network and promote during several events in 2013. The San Antonio AMTA/AWWA (American Water Works Assn.) Joint Membrane Technology Conference & Exposition will...
Biofouling, also known as biological fouling or biological contamination, is the process in which biofilms accumulate on reverse osmosis (RO) membranes, degrading membrane performance and preventing the system from operating at optimal efficiency. A...
Electrodialysis was developed in the mid-1950s to demineralize brackish water at commercial scale. In general, electrodialysis and electrodialysis reversal are considered more appropriate for applications in processes with low total dissolved solids (TDS...
Ozone has been effectively used for disinfection in municipal water treatment applications since the early 1900s. More recently, a growing body of evidence is showing that ozone oxidation is very efficient at removing a whole class of organic compounds...
Homer, Alaska, replaced its obsolete pressure sand filtration water treatment plant with a new robust submerged membrane. Total trihalomethanes (THHM) and haloacetic acids (HAA5) had been high in the city’s long and dead-end distribution system, but with...
When it comes to membrane technology—the water industry’s edgy child—innovative technologies sometimes are mistakenly dismissed as too expensive and only viable as a last resort. This scenario can be summed up with the all-too-familiar adage: “Parents...
