Скачать или смотреть Jar Testing Explained: The Key to Chemical Coagulation and Flocculation Control in Water Treatment

In this video, we explore one of the most important laboratory procedures in the water and wastewater industry — Jar Testing. This essential process helps operators determine the optimal chemical dosage for coagulation and flocculation, ensuring clear water, regulatory compliance, and cost efficiency.

What You’ll Learn:

The science behind jar testing — how colloidal particles stay suspended and how coagulants neutralize their charge

The difference between coagulation, flocculation, and sedimentation

Step-by-step jar test procedure: rapid mix, slow mix, settling, and evaluation

How to use a multi-paddle apparatus, set mixing speeds, and observe floc formation

Key performance indicators: turbidity, phosphorus, sludge volume, and floc density

How to calculate the optimal chemical dose and scale it up to full plant flow

The role of jar testing in process optimization, troubleshooting, and cost control

From understanding charge neutralization to applying real-world results at the plant, this lesson covers everything operators need to know to master jar testing — the cornerstone of chemical process control in wastewater treatment.
