Jar testing, to determine the proper coagulant dosage, goes on 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 and bird

Before starting

The vessel test, just like any coagulant test, only will provide appropriate results when properly performed.

Because the jar test is intended to reproduce conditions in your grow, developing the proper method is important. 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 IN THE GROW. If, for instance, your plant does not have a static or adobe flash 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
