A JAR TEST STUDY ON THE USE OF ALUM FOR TURBIDITY

Jar test were performed as follows: The appropriate amount of 10,000 ppm alum stock was added to each sample, and flash mixed at 220 rpm for 1.25 minutes, thenDetermination of the Optimal Dosage of Aluminum Sulfate in,,NTU, six samples were prepared for each test and the concentration of Aluminum Sulfate were added from 10 mg/L to 35 mg/L, with a variation of 0.5 mg/L between each sample. For the nine remaining experiments with turbidity levels ranging from 260 to 1000 NTU, 10 samples setups were put in place for each level of turbidity.PUBLISHED BY THE NATIONAL ENVIRONMENTAL SERVICES,can do for optimization of the plant is jar test-ing, and jar testing is a must when looking at best available technologies. According to the Phipps and Bird Web site, “We often hear from treatment plants that they want to jar test; they know they should be jar testing; but they just can’t seem to justify the cost of the equipment.
