  • Filtration media for removing chloramine, chlorine and ammonia, and method of making the same
    Patent number: 11648533
    Abstract: An activated carbon-based media for efficient removal of chloramines as well as chlorine and ammonia from an aqueous stream is presented, and a method for making the same. The method involves preparing activated carbon that remove chloramines efficiently from chloramine-rich aqueous media. In particular, this application relates to the use of high performance catalytically active carbon for an efficient removal of chloramine from drinking water in the form of a solid carbon block or granular carbon media. The activated carbon is treated with a nitrogen-rich compound, such as, melamine.

  • Modified activated carbon for adsorption of airborne formaldehyde and method for making the same
    Patent number: 10773235
    Abstract: A modified active carbon material for adsorption of airborne lower aldehydes. The activated carbon is impregnated with triethylenediamine (TEDA) and has a copper deposition. A filter media is formed from a method of preparing triethylenediamine (TEDA) activated carbon with deposited copper for removal of toxic formaldehyde from the environment, such as a process of making surface modified granular activated carbon media that is highly efficient in removing formaldehyde.
