  • General theory for the oxygen transfer

  • As mentioned before the MO need the dissolved oxygen for the oxydation:Biochemical oxydation of carbohydrates: glucose C6H12O6 + 6O2 6CO2 + 6H2O Biochemical oxydation of ammonia (Nitrification) 2NH4+ + 3O2 2NO2- + 2H2O + 2H+ 2NO2- + O2 2NO3+ + 2H2O + 2H+General theory

  • General theory

  • General theoryWHAT AFFECTS THE AERATION EFFICENCY:

  • Oxygen transfer from the air bubble to the liquidGeneral theory

  • Volume VVolume 100% 100% 100%Surface 100% 126% 159%General theoryInfluence of bubble size

  • As a result the smaller the air bubbles are:

    the larger is the bubble surface and by this, a larger contact layer air/water is obtained the longer the retention time will be Due to this facts more oxygen can be dissolvedGeneral theory

  • General theoryInfluence of the temperature

  • General theoryInfluence of the temperature

  • As a result the cooler the water: the higher the oxygen saturation value and due to this the higher the O2 transfer Oxygen transfer tests should be made between +5C and +35C General theory

  • the higher the ambient pressure and due to this the higher the O2 concentration / contact layer

    the longer the retention time will beAs a result the deeper the immersion depth:Due to this facts more oxygen can be dissolvedGeneral theory

  • General theoryCorrection factor of the altitude

  • Influence of the altitude of the plantAnother important point is the altitude of the plant, as the oxygen proportion of air decreases with increasing altitude.

  • 1.) Clean water must be made oxygen-free before measuring --> addition of Na2SO3 or N2

    2.) Switching on the aerator and measure the increase of DO from c = 0 mg/l up to the saturation (3 probes)

    3.) The increase of the dissolved oxygen concentration proceeds very quickly until it runs asymptotically to the saturation value.

  • CONDENSATE REMOVAL Due to the pressure in the air main, moisture in the air and the cooling effect of the effluent, condensation will form in the pipe work

    Drain this water back into the basin by opening the relevant valve

    Drainage can vary from every day to once per month. Monitor the collection of water over the initial operating period

    The water should be crystal clear

    Dirty water means a problem with the system installation

  • Helsinki Viikinmaki Central Treatment Plant, Finland. 20,000 KKI 215 membrane disc diffusers. Population equivalent 750,000. Water depth 12m

  • EFFECT OF DIFFUSER DENSITY ON SOTE AND ENERGY CONSUMPTION3.6kgO2/kWh4.4kgO2/kWh

  • AIRFLOW CONTROL Air main is tapered so that the correct amounts of air go to the relevant zone

    The air taper should deliver the correct amount of oxygen to each zone without valve control

    Pressure losses over the diffuser membrane should be the same therefore no throttling will be required

    Over time some variation in the pressure loss may occur thus resulting in the need for throttling

    Throttle if the zone looks inactive

  • Principle of Magnetic BearingsActive magnetic bearing ( AMB ) consist of two attracting electromagnets, a position sensor and a controller. The electromagnets introduce forces acting on a ferromagnetic rotor pulling it to the opposite directions. Deviating the rotor from the central position towards one magnet increases the force pulling the rotor towards the deviation. Thus the rotor position is measured and the controller decreases the current in the magnet causing the pulling force in the direction of deviation and increases the current in the opposite electromagnet. In an actual AMB system, to levitate a rotor a five axis bearing system is used. Each axis, or channel, has its two electromagnets and a position sensor. Position controller takes care of all the channels keeping the rotor fully levitating.
