  • Patent number: 9358522
    Abstract: A composite medium and method thereof for simultaneous removal of cationic and anionic heavy metals are provided to remove cationic and anionic heavy metals effectively. The method includes dissolving sodium alginate powder into deionized water to provide an alginate solution, and introducing amine group-supported mesoporous iron oxide and synthetic zeolite into the alginate solution and kneading the resultant mixture. The method also includes adding the alginate solution mixed with the mesoporous iron oxide and synthetic zeolite dropwise to an aqueous calcium chloride solution so that each drop of alginate solution is cured to form a bead-like composite medium, and vacuum drying the bead-like composite medium to remove water present in the composite medium, while the mesoporous iron oxide and synthetic zeolite are moved from the inside of the composite medium toward the surface of the composite medium.

  • Patent number: 9295974
    Abstract: The present disclosure relates to a floating type adsorbent for removal of phosphate that can effectively remove phosphate from aqueous phase through reaction between an amine function attached on the surface of a sponge and phosphate. This adsorbent can be regenerated by desorbing the adsorbed phosphate, a method for fabricating same and a method for regeneration the floating type adsorbent for removal of phosphate. The floating type adsorbent for removal of phosphate according to the present disclosure is fabricated by immersing a sponge in a mixture solution of an amine precursor and anhydrous toluene to form an amine function on the surface of the sponge. The amine precursor may be 3-aminopropyltriethoxysilane (APTES) and the APTES and the anhydrous toluene may be mixed at a volume ratio of 0.5-1:1.

  • Patent number: 8980090
    Abstract: Disclosed are apparatus and method for alternative aeration-effluent wastewater treatment using a ceramic membrane, which allows the biological treatment to be performed sufficiently in an intermittent aeration tank by combining an anaerobic tank with a plurality of intermittent aeration tanks and selectively changing an inflow path of influent water according to an operation status of the intermittent aeration tanks. The present disclosure is directed to providing an apparatus and method for alternative aeration-effluent wastewater treatment, which allows the aeration and treated water to continuously discharge through two intermittent aeration tanks by independently forming an air injection line and a treated water discharge line at a ceramic membrane provided in each intermittent aeration tank.
