The jar test is a laboratory procedure designed to simulate and evaluate the coagulation and flocculation processes that take place during water treatment at a plant. This test is fundamental for determining the appropriate dosage of coagulants and the optimal mixing conditions required to effectively clarify water. By using jars filled with water samples and adding coagulants, operators can observe how particles react and settle out under controlled conditions.

This process closely mimics the operations in a water treatment plant, where similar principles are applied to remove turbidity and improve water quality before distribution. The jar test provides vital insights that help optimize the treatment process to ensure safe and clean water is produced for consumer use.
