Testing the product
On Wednesday, August 21 we tested the prototype and received a 17.5 NTU after 42 minutes.
On Friday, August 22 we tested the prototype again and received a 0 NTU after 41 minutes.
The difference between the two prototypes were that we added a coffee filter above the final collection. Also, the tube that we used was dirty so every time that we ran the prototype, the tube got cleaner. Both of these changes added to the success.
