These are the results of the first several experiments run, with the initial experimental setup. This setup consisted of the flow accumulator and vertical glass filter column. A dissolved oxygen (DO) probe in the flow accumulator recorded the dissolved oxygen concentration of the inflowing tap water. The flow rate and temperature of the water was monitored by a pressure sensor and temperature probe inside the flow accumulator and controlled by valves on the hot and cold water lines. These valves were opened and shut by the program Process Controller ProCoDA Software. Once the water had run through the filter column, it was collected in a small beaker containing another DO probe, which recorded the dissolved oxygen concentration of the outflowing water.
