Using the design specifications from Figure 1, the following piping and instrumentation diagram was developed. It integrates the system that last year’s cavitation team developed with a UV reactor to facilitate research on the combined effects of the two purification systems.

The system has four modes of operation: cavitation only, UV only, cavitation to UV, and UV to cavitation. It can be operated at various pressures and flow rates in accordance with the engineering specifications. The operational mode can be changed by adjusting the valves as described below.

To run the system in cavitation only mode, valve 1 (V1) is turned to a position that allows flow to the cavitation device but not down the bypass branch. Valve 2 (V2) is closed and Valve 3 (V3) and Valve 4 (V4) are opened. This is illustrated in figure 2.

To run the system in UV only mode, Valve 1 is turned to a position that will close off the branch that leads to the cavitation device and allow flow to the bypass branch. Valve four is closed and valve three and two are opened.

To run the system with cavitation and the UV in series, Valve 1 is positioned to allow flow through the cavitation device but not through the bypass branch. Valves 2 and 3 are both opened to allow most of the flow to go through valve three but pass a portion to the UV reactor. The water that runs through the UV reactor can be collected for testing by the sample port, Valve 5 (V5).

Finally, to run the system with the UV and then cavitation in series, the system is first set to UV only mode. After a suitable period of time, the system is then switched to cavitation only mode. In this way, the effects of cavitation on UV treated water can be studied.

Although the WTHC team has collaborated on almost every aspect of this project, the following major responsibilities have been assigned.
