Surface foam is formed at the end of the rapid mix in AguaClara plants. It was observed in pilot plant (Here at Cornell) that the freefall of water jets from the LFOM resulted bubble formation due to aeration in the water. This experiment was set in order to study the relationship between the freefall jets and foam formation under different parameters.
Three parameters were investigated to study foam formation:
        1) Average velocity of jets (assuming the jets from the Orifices joined before hitting the surface of the water below the LFOM)

        2) Type of surface (the surface, which the jets hit, a plan or water)

        3) Length the water travels down the incline plane(jets after hitting incline plane)

For this experiment, dial soap mixed in water, a pump, a flow accumulator, a water tank and a water container were used in order to create water jets that similar to those found in the LFOM.
