Similar analysis was performed for all of the System 2 Tanks. The system 2 Tanks were 20 ft
high tanks had a ring-bubbler agitator system installed in recommended positions (Treybal
1987). Most of the mass transfer occurs in the zone between the impeller and the bubbler system.
This system worked extremely well. However, the data obtained is of little use because of
various activities the author had no control over. However, a method of PID operation was
determined and used based on these methods.
