Phipps and Bird - THE JAR TEST

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

Before you begin

The container test, much like any coagulant test, only will provide correct results when properly performed.

Because the jar test is intended to replicate conditions in your grow, developing the proper method 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 HINGE ON CONDITIONS INSIDE YOUR FLOWER. If, for instance, your plant does not have a static or expensive mixer, starting the test at high rpm would provide misleading results. This kind of rule applies to flocculator speed, length of negotiating time and floc developement. Again, operate the vessel test to simulate conditions in YOUR plant. phipps & bird
