Course Pack: Jar Testing Fundamentals & Process Optimization
Jar Testing – Standard Procedures and Operational Simulation
Course Description
This module provides Jar Testing Standard Procedures focused on conducting accurate jar tests that closely represent real plant conditions. Learners explore step-by-step methods for chemical dosing, mixing intensities, and simulating full-scale treatment processes such as flash mixing and flocculation. Through this Jar Testing Standard Procedures training, operators gain practical skills to perform reliable tests, evaluate treatment performance, and improve chemical dosing decisions for effective water treatment operations.
Learning Objectives
1) Grasp the basic steps of jar testing: sample prep, chemical dosing, and stirring
2) Simulate plant conditions, including flash mixing, flocculation, and settling, with jar testers
3) Learn to set chemical doses and mixing levels for optimal coagulation and microfloc formation
4) Understand how parameters like alkalinity, pH, and temperature affect jar test results
5) Develop skills to analyze jar test outcomes for plant operations and dosing confirmation
Agenda
1) Standard jar testing procedures and settling assessment
2) Dose response evaluation for coagulant/performance checks
3) Proper use of instrumentation and data interpretation
4) Troubleshooting common test issues
Target audience
Operator Level 1–2 personnel conducting routine jar testing, evaluating coagulant performance, or supporting optimization initiatives.
