Researchers create thin film polymer membranes capable of separating fluoride from chloride and other ions. Targeted ion selectivity by the filtering membranes could have important implications for water purification, environmental remediation and industrial production.
Researchers reporting in ACS’ Environmental Science & Technology have discovered that a standard water treatment technique, called iron (III) coagulation, and its electrically driven counterpart, iron (0) electrocoagulation, can efficiently remove and inactivate a model enveloped virus.
Researchers from NUS have discovered a new strain of bacterium that can remove both nitrogen and phosphorous from sewage wastewater. Their findings offer a simpler, cheaper and greener method of wastewater treatment.
LLNL researchers have created carbon nanotube (CNT) pores that are so efficient at removing salt from water that they are comparable to commercial desalination membranes. These tiny pores are just 0.8 nanometers in diameter. In comparison, a human hair is 60,000 nanometers across.
UPTON, NY – A collaboration of scientists from the National Synchrotron Light Source II (NSLS-II), Yale University, and Arizona State University has designed and tested a new two-dimensional (2-D) catalyst that can be used to improve water purification using hydrogen peroxide.
