Test 1: Reduce COD, NH3 and foam with Aquafix products
Results for COD and NH3 reported in mg/L. 50ppm Urea was added to each jar on days 2, 3, and 4.

Conclusions:
- There was no foam in any of the test jars during the duration of testing.
- Adding 20ppm of Qwik-Zyme P or Foam Buster after every day for 5 days seemed to reduce COD and NH3 further than the other products tested and the control.
- There seems to be some protein in this waste stream since the ammonia was higher in the test with Qwik-Zyme P after day 1 than it was with the addition of any of the other products or the control. This is probably due to the breakdown of proteins, which in this case are concentrated in the bacterial EPS.
- For all products tested, COD may increase a little after 1 or 2 days but then will drop by day 4 and 5.
