Title: Are we treating Beakers? Or Systems? Pitfalls in Laboratory Simulation
The learner will view laboratory testing form a perspective of "Does this correlate to what happens in the field"
CLean or Dirty
Time is of the essence
Shear force and deposition, removal
Realistic cxhemistry of forced to fail (miine fails less than yours si good?)
Correlating to the field (What happens in the wild?)

Lavboratory testing of water treatment programs for scale and corrosion cotrol. are run and used for several purposes:
* To evaluate new inhibitors and treatments and predict field performance over a range of systems.
* To optimize dosages and determine the minimum effective dosage.
* To compare exisitng treatments to proposed treaments.
* To develop "technically accurate and appropriate"data for sales literature and promotion.
* To explore new areas such as inhibitor interaction with respect to sysnergy and antagonism.
Results should correlate well to field results under the same or similar conditions. This presentation discusses parameter selection and test experimental design to avoid pitfalls resulting in stellar results in a beaker, and abject fialure in the wild.
Rob Ferguson joined the water treatment industry in 1974 as an apprentice to Dr. Art Freedman. He pioneered dosage modelling, computer simulation, and online, real time control of scale inhibitor feed in the 1970's and has been a frequent contributor to the industry. He cofounded French Creek Software with his wife Janet in 1989. Rob is proud to hve been recoginized by the AWT membership as Supplier of the Year, with the Ray Baum Memorial Water Technologist of the Year Award, and as the First AWT Innovation Award recipient.
