  • SURFACE-MODIFIED ACTIVATED CARBON FOR REDUCED BACKWASHING FREQUENCY DURING PARTICULATE FILTRATION
    Publication number: 20240024846
    Abstract: There is provided herein a method of reducing the backwash frequency required in water treatment facilities which includes utilizing a surface-modified activated carbon. A method of preparing said surface-modified activated carbon is also provided. The method of preparing may include oxidizing an activated carbon with a chemical oxidant, which may result in surface functionalization of the activated carbon.

  • Mesoporous activated carbon and methods of producing same
    Patent number: 10449512
    Abstract: Mesoporous activated carbon is disclosed. In at least some embodiments, virgin activated carbon to be processed may be coconut shell-based. The enhanced activated carbon may have a mesopore structure of at least about 10%. The enhanced activated carbon may be produced through a calcium-catalyzed activation process. A chelator may also be used. Catalyzed thermal activation may be carried out until a desired mass loss is achieved.
