A foam fractionation protein skimmer for removing organic waste material from organic loaded water, the protein skimmer including an upright reaction chamber with an uppermost throat in flow communication with a foam collection cup for collecting a protein loaded foam containing the organic waste material. The chamber has a vertically directed partition with an uppermost portion terminating beneath the throat for partitioning the chamber into an upwardly converging inlet compartment and a downwardly diverging outlet compartment respectively having an inlet port and an outlet port downwardly remote from the throat, and a region of flow inversion for inverting an ingressing air/protein loaded water mixture upwardly flowing toward the throat to an egressing water flow downwardly flowing to the outlet port with an upward counterflow of protein bearing air bubbles The upward counterflow of air bubbles combines with foam fractionation occurring at the region of flow inversion to produce the protein loaded foam at the throat whereby the egressing water flow is less protein loaded than the ingressing air/protein loaded water mixture.
