All aspects of water resources, including hydrology, water quality, aquatic ecosystems, water treatment technologies, water resource management, and solutions for water scarcity
4 papersThis study investigated the use of fenugreek and okra-derived polymers for removing microplastics from various water sources. Fenugreek was most effective in groundwater, a combination of fenugreek and okra worked best in freshwater, and okra alone excelled in ocean water, all outperforming traditional polyacrylamide.
A case study of 19 U.S. water systems found that installing filtration for PFAS often reduces other contaminants like trihalomethanes and haloacetic acids, beyond what the 2024 EPA analysis estimated. Many water systems with high PFAS levels also have other contaminants exceeding health guidelines, suggesting broader benefits from PFAS treatment.
Researchers developed a new method called SARIP, which uses soap to make the tiny holes in water filter membranes more uniform. This improved uniformity allows the membranes to separate tiny molecules and ions with greater precision than before, potentially revolutionizing water purification and other separation processes.
The review examines various methods for removing heavy metal ions from wastewater, including adsorption, membrane filtration, chemical treatment, electrochemical methods, and photocatalysis. Adsorption techniques are currently the most researched, but face challenges in removing diverse ion types concurrently and maintaining adsorbent stability. The review emphasizes the need for more research using real wastewater to develop eco-friendly, cost-effective, and sustainable treatment solutions.
