The team believed it was best to prototype the way the system would clean the water and kill E. Coli. contaminants. The team did this by looking into codes and standards of how to effectively disinfect the water. The CDC requirement was that water for the wash and pack station must contain zero CFU organismic colonies of E.Coli. Because that is a main priority in the project, it was deemed one of the first action items. After this, the team researched different methods of eliminating E.Coli: boiling hot water, ultraviolet light treatment, and bleach injection. Ultimately, the final selection was to focus on bleach injection due to the other two methods requiring more energy which goes against LaFarm’s efforts to use less energy and transition to renewable energy efforts.
