Jar testing should be performed regularly during non-water quality events to develop and maintain the necessary skills and confidence to be able to confront real water quality changes.
Jar Testing of Chemical Dosages. Prepared By. Michigan Department of Environmental Quality. Operator Training and Certification Unit.
With a jar test, we are attempting to predict the performance of our flash mixing, flocculation, and sedimentation processes by duplicating the plant performance in a small volume test.
Jar testing can be used as a tool to help select the proper coagulant and dose for the reduction of pathogens and disinfection by-product pre-cursors.
The equipment, systems, and installations whose functioning is required by the JAR and national operating regulations must be designed to ensure that they perform their intended functions under any foreseeable operating conditions. (See ACJ's Nos. 1 and 2 to JAR 25.1309.)
Jar method for determining the proper dose rates of chemicals utilized when treating wastewater. It is a miniature batch treatment tank with all the variables under control of the operator. It usually consists of a “jar” or beaker of a known volume and a variable speed mixer.
