The Chemical Dose Controller team is travelling to Washington, D.C. in April 2009 to compete for a Phase II grant in the EPA P3 competition. The rapid mix tube was designed under the chemical dose controller team and plays an important role in the dosing process, and the rapid mix tube is thus included in the EPA project proposal and will be a part of the display at the competition in Washington, D.C. A scale version of the rapid mix tube developed in the Fall 2009 semester and refined in the Spring 2010 semester was developed to be taken to the conference and demonstrate the concept of rapid mix and how it relates to water treatment.

The design of th EPA scale rapid mix tube is almost exactly that developed for use in the AguaClara treatment plants, simply scaled down to provide a smaller tube and accommodate a small flow rate of water through the system. A separate [MathCAD| file was developed, however, to provide the full design for the EPA rapid mix tube. The flow rates of water through the tube, as well as the size and diameter of the tube itself have become mush smaller, requiring some adjustments to the original tube design. The most notable changes include:
...
Photos of the dye flow through the system will be posted as soon as they are taken after further experimentation.
