Jar Test. Jar testing is a pilotscale test of the treatment chemicals used in a particular water plantIt simulates the coagulation/flocculation process in a water treatment plant and helps operators determine if they are using the right amount of treatment chemicals and thus improves the plant's performance.

Representative jar testing means that the jar test procedure will imitate the coagulation flocculation and settling conducted in the water plant There is no single jar test procedure will duplicate all of these processes for all plants however experience shows that jar test procedures can be individually tailored to accurately predict.

run sidebyside and the results compared to an untreated jar or one treated with the current program The general procedure for jar testing is as follows 1 1 Fill the appropriate number of (matched) 1000 mL square transparent jars 2 with wellmixed test water using a 1000 mL graduate 2 Place the filled jars on the gang stirrer with the paddles positioned identically in each beaker.
Jar Test Procedure for Precipitants, Coagulants
Jar test is a pilotscale laboratory test that simulates coagulation or flocculation with differing chemical doses The purpose of the jar test is to estimate the minimum coagulant dose required to achieve certain water quality goals Jar tests are conducted on a four or sixplace gang stirrer which can be utilized to simulate mixing and settling conditions in a clarifier.

Pour a sample of untreated wastewater into a beaker (ex 300 ml) While mixing adjust the pH using caustic soda or While stirring the sample use an eyedropper to add the precipitant until the ORP value drops rapidly by 150mV Add 1 or 2 drops of coagulant solution Mix at high speed for 1 to 3 minutes Turn off mixer and observe the After several minutes a sample of clear supernate may be taken for metals test or the entire contents of beaker (s).
