Water Sterilization

The Water Sterilization Group, led by members Chris Robertson, Courtney Green, Jacob Frye, and Scott Shields, is dedicated to designing and testing a highly effective fluid chamber. This innovative system aims to sterilize water contaminated with E. coli using a 10 kV DC power source, delivering 1 pulse per second. Key activities include testing various voltage and flow rates, maximizing the kill rate of E. coli, and developing a peristaltic pump to ensure optimal volumetric flow. Our goal is to reliably and efficiently disinfect water while documenting performance metrics.

  1. Water Sterilization Group Members: Chris Robertson Courtney Green Jacob Frye Scott Shields

  2. Goals • Design, Manufacture, and Dye test a working fluid chamber that fulfills the following constraints: • DC Power Source with 10 kV • 1 Pulse per a second • Highly conductive material for the discharging plates • Ability to sterilize a cup of water in a reasonable time • Peristaltic pump to create the volumetric flow rate • Calculate and document achievable flow rates Completed

  3. Test Stand with chamber design #1 Designed to contain all E-coli contaminated lost liquid Angle design to dislodge any trapped air from the electrode plates

  4. Designs Comparison

  5. Extra Circular Activities • Test the fluid chamber with E-coli • Culture the E-coli • Determine the kill rate and Effectiveness of the designs • Try different Voltage and Flow rates In Process
