 Single - Variable Optimization Approach 

Either the pH or coagulant dose is varied while the other is held constant. 

The next generation jar test procedure has been in development since 2014 and I'm excited to announce that it is finally ready!

We've been diligently working on perfecting the procedure as well as creating tools and supporting materials that make jar testing simple and easy for everyone, regardless of experience or background. 

Getting Started

1. Basics of jar testing and demonstration 

2. JTWizard

JTWizard is an interactive excel-based jar testing program that guides and assists users in performing jar tests. All experimental data is stored within JTWizard and can be accessed easily. It's also free! 


The video below is an in-depth tutorial on using JTWizard.  It covers almost everything you would need to know to start using the tool.

3. Jar test manual

4. Granular media filtration system

5. Standard model water

A standard model water was created which can be used for training and procedure validation purposes.
