Jar Testing Gets An Upgrade

By Katherine Macchiarola and Jeff DeNigris, Malvern Panalytical

Jar testing is a common laboratory procedure used at water and wastewater treatment plants to determine optimum conditions for the coagulation / flocculation process. In a set of beakers a defined amount of water is mixed with varying amounts of coagulant, and through observation by a trained operator the optimal amount of coagulant can be determined.
