  • Water denitrification process using air stripping (REC-3603)
    Patent number: 5863444
    Abstract: A water denitrification process is provided which comprises stopping the reduction of nitrate at nitrite, lowering the pH of the water, and then gas stripping the nitrite out of the water by using air as the gas in a sparger. This allows considerable savings to be realized based on the reduced chemical removal costs as compared to other water denitrification processes.

  • Water treatment process for nitrate removal
    Patent number: 5616252
    Abstract: An ion exchange process utilizes a chemical system in which sodium nitrate is reacted with an acidic solution of urea to selectively precipitate nitrate ions from waste brine in the presence of chloride ions, thereby allowing for the recycling of the brine regenerant.
