Claim 17:
18. A water treating apparatus comprising a plurality of saturators connected to each other in series, each of the plurality of saturators comprising:
a cylindrical chamber in which a first flow path through which water flows is formed;
a plurality of porous membranes disposed in the first flow path, each of the plurality of porous membranes being in a cylindrical shape and forming a second flow path through which compressed air flows, the second flow path extending in an axial direction of the cylindrical chamber and being configured to be connected at one end to an air compressor so that the compressed air flowing in the second path passes through the porous membranes from the second flow path to the first flow path to be dissolved in the water flowing in the first path;
a water inflow part formed in a pipe shape at a side wall of an upstream side of the cylindrical chamber;
a water outflow part formed in a pipe shape at a side wall of a downstream side of the cylindrical chamber; and
a compressed air inflow part formed at the upstream side of the cylindrical chamber adjacent to the water inflow part and connected to the air compressor configured to supply compressed air to the second flow path,
wherein the plurality of saturators includes:
an upstream end saturator having a dedicated water inflow part connected to a water supply apparatus configured to supply water to the first flow path of the upstream end saturator;
a downstream end saturator having a dedicated water outflow part connected to a floatation apparatus including a space in which a foreign material floats in saturated water from the downstream end saturator; and
at least one intermediate saturator connected between the upstream saturator and the downstream saturator, each of the at least one intermediate saturator having a dedicated water outflow part configured to engage with a dedicated water inflow part of another saturator of the plurality of saturators,
wherein each of the at least one partition wall is formed with a plurality of membrane through holes, through which the plurality of porous membranes passes, and a plurality of water through holes, other than the plurality of membrane through holes, through which the water passes, thereby producing a vortex.
