ABSTRACT:
In a method and apparatus for treating an organic liquid waste with a biofilm, the organic liquid waste is dissolved with oxygen under a first pressure higher than an atmospheric pressure to prepare a pressurized oxygen-dissolved organic liquid waste. The pressurized oxygen-dissolved organic liquid waste is depressurized to prepare a depressurized oxygen-dissolved organic liquid waste. The depressurized oxygen-dissolved organic liquid waste contacts the biofilm to prepare a treated organic liquid waste.
