Optimized Alumina Coagulants for Water Purification

Technology Summary

This innovative technology uses a water treatment coagulant, or reagent, to facilitate the process of water purification. By inserting a single gallium atom in the center of an aluminum oxide cluster, the stability and efficacy of the reagent is greatly improved. This stability also provides a longer shelf life, increased effectiveness in various environments, and outperforms other current commercially available coagulants for water clarification and pathogen removal.

Description

Several significant applications of this development exist. Since water is an essential resource for daily life, a reliable supply is a necessity. However, access to clean and safe water sources can be problematic in certain populations, areas of the world, and in emergency situations. The key benefit to this technology is the efficiency of the coagulation process as a front-end treatment means less chlorinated by-products in the potable water.

Benefits

  • Greater stability of molecules
  • Longer shelf life
  • More efficient in water decontamination
  • Increased performance reduces amount of disinfection by-products

Applications and Industries

  • Water supply
  • Sewage treatment
  • Emergency usage
