NUS scientists develop a new class of artificial water channels for more efficient industrial water purification

Scientists from the National University of Singapore have successfully synthesised a special protein-mimic that can self-assemble into a pore structure. When incorporated into a lipid membrane, the pores permit selective transport of water across the membrane while rejecting salt (ions).

Don’t wait, desalinate: new water purification system cuts cost, energy expenses

A water purification system created by researchers at the Beckman Institute for Advanced Science and Technology separates salt and unnecessary particles with an electrified version of dialysis. Successfully applied to wastewater, the method saves money and saps 90% less energy than its counterparts.

Chula Engineering Cures Salty Tap Water with NanoTech

During the dry season this year, Bangkok residents have faced the saltiest tap water problem in 20 years as a result of global warming and seawater rise. Chulalongkorn engineers predict the problem to persist until May and have proposed solutions with desalination technology.

Unorthodox Desalination Method Could Transform Global Water Management

Over the past year, Columbia Engineering researchers have been refining their unconventional desalination approach for hypersaline brines—temperature swing solvent extraction (TSSE)—that shows great promise for widespread use. The team now reports that their method has enabled them to attain energy-efficient zero-liquid discharge of ultrahigh salinity brines—the first demonstration of TSSE for ZLD desalination of hypersaline brines.

Polluted Wastewater in the Forecast? Try A Solar Umbrella

Evaporation ponds, commonly used in many industries to manage wastewater, can occupy a large footprint and often pose risks to birds and other wildlife, yet they’re an economical way to deal with contaminated water. Now researchers at Berkeley Lab have demonstrated a way to double the rate of evaporation by using solar energy and taking advantage of water’s inherent properties, potentially reducing their environmental impact. The study is reported in the journal Nature Sustainability.
