What is a jar tester and what does it measure?
Zusammenfassung
The purpose of jar testers.
Antwort
Jar Testing is a method of simulating a full scale water treatment process (specifically the initial coagulation process that helps remove suspendid solids from water). For each sample, several beakers (Jars) are filled with the sample water. Each jar represents a full scale water treatment tank. Chemical agents (flocculation agents) are then added in different doses and the stirrer is turned on. After the stirring process is complete, the amount and quality of floc is compared in each jar to see which results are best. Other parameters such as mixing rate, aeration level/tim, filtration type, etc. can also be altered in each jar to see how they affect sample coagulation.
