Ammonium Sulfate

JAR Test Method

After putting the 500-ml testing solution in the 500-ml beaker, add the reagent continuously using the mess pipette while stirring at 100-120 RPM. Rapid stirring for 1-2 minutes is continued for dispersion. Continue slow stirring at 50-60 RPM for 10 minutes for FLOC growth, and stop stirring for 5-6 minutes.

Measure the size and precipitation state of FLOC and the turbidity, pH, COD and BOD using the upper 100 ml, to determine the best condition.

01. Adjustment of the Turbidity, pH and Alkalinity of the Original Solution before Its Addition.
02. Stirring - The condition mentioned above is standard.
Adjust it appropriately according to the stirring condition of your treatment.
03. If an organic macromolecular agglutinating agent is used together with the reagent, the reagent is added first and stirred for 10-60 seconds. Then the organic macromolecular agglutinating agent is added and the mixture is stirred slowly but continuously.
04. Adjustment of the Aluminum Sulfate Solution for the Self-test

The table below shows the amount of agglutinating agents that should be added to the diluting solutions.
