Description:
The jar test has been and is ah important drinking water treatment plant design, process control, and research tool. n the drinking water field, the jar test is described as a "bench-scale" simulation of full-scale coagulation/flocculation/ sedimentation water treatment processes. he jar test protocol must be designed to mirror as well as possible the conditions (ie. coagulant and chemical addition points, mixing energies and times, and floc qualities) at a particular full-scale water treatment plant. n other words, the jar test procedure is site specific and no standard jar test protocol exists. esults from a jar test are particularly valuable to the plant operator in making adjustments to treatment process(es) in reaction to water quality changes. hen properly performed, and full-scale treatment conditions are reasonably represented, the jar test can be used to assist plant operators and engineers in adjusting treatment processes to meet goals or criteria at minimal costs. his paper describes features of the jar test apparatus and presents a general outline of a jar test procedure. actors that are critical to producing consistent and representative results are also discussed.
