substituting a single atom in a molecule commonly used to purify water, researchers of Sandia National Laboratories have created a more effective decontamination and longer shelf life than existing products on the market.
clean material contaminating bacteria, viral and other organic and inorganic, the river water for human consumption, and wastewater treatment plants before being returned to the environment.
The drinking water of questionable safety is increasing all over the world to the growing global water scarcity. Technological advances such as this can help solve the problems faced by water treatment facilities in both developed and developing nations developing.
The lead investigator for Sandia Laboratories for this project is May Nyman.
The reagent for water treatment is obtained by substituting a gallium atom in the center of a cluster of molecules of aluminum oxide.
The substitution of a single gallium atom in the compound is a huge difference. Greatly improves the stability and effectiveness of the reagent. Researchers have tested a wide variety of commercially available products. For almost every case, the improved product by Sandia Laboratories performs its function better under a wide range of conditions.
Facing the great variability conditions is inevitable when dealing with a natural water source such as a river. There are seasonal and even daily fluctuations in pH, temperature, turbidity and water chemistry. And a river in an area is under very different from a river in another area.
The product of Sandia attracts and traps contaminants as well as electrostatic charge remains more reliably than conventional products.
The new material also has less tendency to thicken into larger aggregates and less reactive during storage before use. This means you can be kept in good condition longer than products commercially, which are compressed over time.
The chemical substitution of one atom of an aluminum gallium had been studied by the staff of Sandia Laboratories at the University of California at Davis, but no one had used this knowledge in an application like the removal of contaminants water and microorganisms.
