Experimental Method for Limiting Parameters of Foam Formation from Water Jets

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

        2) Type of surface

        3) Length the water travels down the 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.
