Abstract
A foam fractionation protein skimmer assembly/apparatus for removing organic waste material from water within an aquarium includes a foam fractionation column adapted to be partially submerged in the water in an aquarium and an aerating water pump which mixes air with water drawn from the aquarium internally within the pump and pumps the aerated water into the column through an external water intake port on the column to provide a downward flow of water in the column counter to air bubbles rising within the column to induce production of surfactant-containing foam on the surface of the water within the column. The column itself is comprised of a plurality of separate tube sections or chambers frictionally connected together for ease of assembly and disassembly to facilitate cleaning of the column.
