  • METHOD AND APPARATUS FOR CULTURE OF ANAEROBIC AMMONIUM OXIDIZER
    Publication number: 20160176743
    Abstract: The present disclosure provides an apparatus for enrichment culturing of anaerobic ammonium-oxidizing bacteria, including: a reactor containing a culture medium containing ammonium and nitrite; and activated sludge beads in which the anaerobic ammonium-oxidizing bacteria in the culture medium are supported, wherein the amount of the activated sludge beads is 25-35% based on the volume of the culture medium. Because loss of the anaerobic ammonium-oxidizing bacteria is minimized and the beads have good mechanical strength, the apparatus for enrichment culturing of anaerobic ammonium-oxidizing bacteria can be operated for a long time.

  • Apparatus and method for alternative aeration-effluent wastewater treatment using ceramic membrane
    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.
