Abstract:
1. A method for the treatment of liquid comprising organic waste-based material, the method comprising: continuously introducing the material at the upper part of a vertical mixing vessel, subjecting the introduced material to mixing, passing the mixed material on into a first reactor tank for acid treatment, wherein the first reactor tank has disposed therein a first rotary processing means having a first plurality of counter rotating arm-rings, subjecting the mixed material to an impact action via the first rotary processing means as the mixed material therein sinks through the first reactor tank, passing the material from the first reactor tank into a second reactor tank for ammonia treatment, the second reactor tank having disposed therein a second rotary processing means having a second plurality of counter rotating arm-rings, subjecting the material in the second reactor tank to an impact action via the second rotary processing means as the material therein sinks through the second reactor tank, and subsequently drying the material in a drier until a desired solids content is achieved, wherein every arm-ring of the first and second plurality of counter rotating arm-rings simultaneously moves in a direction opposite the direction of an adjacent arm-ring.
