1. A nozzle for a dissolved air flotation system, comprising:
a housing of a tube type which has an inlet formed at one side and an outlet formed at another side;
a nozzle connector that couples to the inlet and has an inflow path formed in a longitudinal direction; and
a nozzle body disposed in the housing, the nozzle body including:
a collision portion formed at a first end portion of the nozzle body such that a fluid introduced along the inflow path of the nozzle connector changes its flow direction and collides with an inner wall of a side portion of the housing,
a plurality of faces formed at sides of the nozzle body,
a plurality of side paths defined between the faces and the inner wall of the housing,
a spurt hole defined at a second end portion of the nozzle body, the second end portion being defined as an opposite to the first end portion,
a collision plate disposed at the spurt hole, and
at least two orifices respectively defined between the faces and the spurt hole such that the fluid sprayed through the orifices collides with the collision plate.
