A new membrane developed by Rice University selectively filters out lithium from brines, achieving high selectivity and using considerably less energy. The membrane's design can be adapted for other valuable minerals like cobalt and nickel, and its durability makes it suitable for large-scale synthesis.
Researchers at the University of Illinois have created an electrochemical strategy to capture, concentrate, and destroy PFAS from water using a single device. The new process combines redox electrodialysis with electrosorption to effectively remove ultra-short-chain PFAS molecules.
A UTEP student has developed an innovative method to desalinate water, which converts over 90% of salt water to fresh water. The new technique, called salt-free electrodialysis metathesis, uses ion exchange membranes and electrical currents to separate salt from water.
The system removes salt from water at a pace that closely follows changes in solar energy, maximizing the utility of solar power. It produces large quantities of clean water despite variations in sunlight throughout the day, making it an attractive solution for communities with limited access to seawater and grid power.
Researchers at the Beckman Institute developed a new purification system that uses an electrified version of dialysis to separate salt and other unnecessary particles from wastewater. The method saves money and saps 90% less energy than its counterparts, making it a promising solution for global water scarcity.
Researchers developed poly(alkyl-biphenyl pyridinium)-based anion exchange membranes with hydrophobic side chains, achieving high permoselectivity for monovalent ions like chloride and hydroxide. The new membranes show excellent alkali stability and can separate multiple multivalent anions with high selectivity.
Researchers at MIT and Saudi Arabia have developed a method to remove salt from produced water using electrodialysis, which can be economically viable for treating extremely high-salinity water. The technology could reduce the need for fresh water from other sources and minimize contaminated water disposal.
Researchers at MIT have developed a solar-powered desalination system that can provide clean drinking water to villages in India. The system, which uses electrodialysis technology, is more energy-efficient and cost-effective than traditional reverse-osmosis systems.
