The development of technology on flotation in water-waste treatment is very fast. This environmentally friendly technology using bubbles. The characteristic of the bubble causes the material to separate into the material hydrophilic or hydrophobic. Obviously with the addition of other chemicals. At the time of bubble formation, air entrainment events occur. This study aims to determine the parameters that affect the entrainment of air events that is the relationship of diameter downcomer and jet velocity to air entrainment. Set up tools used are pump, nozzle, downcomer, flow meter, reducer and glass water tank. All that is connected with the pipe, the data obtained in the form of video and photos using the camera. From there obtained quantitative and qualitative data, for quantitative data in the process using image processing program. Results from this research that jet velocity affects air entrainment, whereas the diameter of the downcomer affects the value of the air entrainment.
