Jar testing, to determine the proper coagulant dosage, proceeds to be one of the very most effective tools available to surface water plant workers. Finished water quality, cost of production, length of filter runs and overall filter life, all rely upon the proper application of chemicals to the organic water entering the treatment plant. phipps & bird

Before starting

The container test, much like any coagulant test, will simply provide exact results when properly performed.

Because the jar test is intended to imitate conditions in your seed, developing the proper treatment is essential. Take time to observe what happens to the raw water in your plant after the chemicals have been added, then simulate this during the jar test. THE RPM OF THE STIRRER AND THE MINUTES TO COMPLETE THE TEST COUNT ON CONDITIONS INSIDE YOUR FLOWER. If, for instance, your plant does not have a static or display mixer, starting the test at high rpm would provide misleading results. This kind of rule applies to flocculator speed, length of deciding time and floc developement. Again, operate the vessel test to simulate conditions in YOUR plant. phipps and bird
