Static Bottle Test

Two incompatible waters with the tendency to form scale are combined in a glass bottle, heated and any scale precipitated is observed. This test is primarily qualitative and gives an indication of which products are working under the scaling regime in test. The results act only as a primary selection process for removing chemicals with intolerance to the brine and those that give no protection. The test can be made quantitative by weighing the mass of scale precipitated, however a more effective means of quantifying scale inhibitor efficiency is to calculate scaling ion concentrations after any scale has formed.

ZODIAC MARINE SERVICES AND INTERNATIONAL CHEMICALS PARTNERS recommend the testing of all products under static and dynamic conditions to obtain a product recommendation because the Dynamic scaling loop favours calcium carbonate formation over short timescales whereas the static jar test favours sulfate scaling over extended timescales.
