  • METHOD FOR THE REMOVAL OF SUBMICRON PARTICULATES FROM CHLORINATED WATER BY SEQUENTIALLY ADDING A CATIONIC POLYMER FOLLOWED BY ADDING AN ANIONIC POLYMER
    Publication number: 20140319069
    Abstract: A method for removing submicron colloidal particulates, such as hydrocarbons, from water. The method includes first adding a soluble, cationic polymer, such as chitosan, a salt, or solution of chitosan to water containing the submicron particulates and a halogenating agent, followed by adding a soluble, anionic polymer or anionic salt to the water. The resulting flocs are filtered to remove the submicron particulates.

  • BENZOIC ACID CONTAINING COMPOSITION FOR MAINTAINING HYDANTOINYLATED POLYMERS IN A BIOCIDALLY ACTIVE STATE
    Publication number: 20090214610
    Abstract: A tablet includes benzoic acid and trichloroisocyanuric acid. The tablet provides free available chlorine in water to maintain an N-halamine-containing polymer biocidal, without rendering the water undrinkable from high chlorine content. The tablet may be used in a water purification device having a cartridge containing an N-halamine polymer to provide safe drinking water.
