More dye experiments were performed through the remainder of the Spring 2010 semester leading up to the EPA conference. The following images and video were captured during on of these experiments. It should be noted that the flow of water and dye through the rapid mix display tube were altered to provide a good visual, conceptual effect for these demonstrations. When operating as designed in AguaClara plants, the alum (represented by the dye) will immediately appear dispersed throughout the upper portion of the tube following the macro-scale mixing orifice; this scale tube produces this uniform mixing immediately when run using the same parameters it would encounter in plant flow, however, only photos of the display parameters are shown here:
