JAR TESTS
1. PREPARATION OF THE SOLUTION
To carry out the jar tests prepare as minimum 10% (Weight/Volume) solutions of QUIPRAHC Q4c. To prepare the solutions weigh 10 grams of product and complete to 100 ml with filtered water. 1 ml of this solution equals to 100 ppm in beakers of 1 liter. For increased precision use 1 ml syringes. Prepare these solutions daily.
2. EXECUTION OF THE TEST
Start with a ratio from 1 to 2 with regard to the solid aluminum sulfate or from 1 to 3 with regard to the liquid aluminum sulfate.
Example:
If the plant has been using 40 ppm of solid aluminum sulfate, then carry out tests with 17, 18, 19, 20, 21, 22 ppm of QUIPRAHC Q4c.
If the plant has been using 90 ppm of liquid aluminum sulfate, then carry out tests with 24, 26, 28, 30, 32, 34 ppm of QUIPRAHC Q4c.
Useful tips:
Perform the trials with the actual times of mixing, flocculation and sedimentation of the water plant.
Measure turbidity, pH and any other convenient parameter, for instance the residual aluminum content.
