The Demo Plant was run at a flow rate of 100mL/min with fresh, one, two, three, and four day old alum solution while recording the turbidity with respect to time for each run. From this it was determined if aged alum has an effect on particle coagulation.

Trial One:
Trial Two:
Conclusion
The results suggest that there is no conclusive evidence showing that allowing alum solution to age effects its ability to coagulate particles.
