Below is a Table showing the resuits from a Jar test conducted to determine the optimal dosage of alum to treat a specific surface water. Applying the definition of optimal dosage, the results of this experiment show that the optimal dosage was most closely Table: Jar Testing Results (2.0 Lor Raw Water was treated in each Jar) Jar #1 Jar #2 Jar #3 Jar #4 Jar #5 Jar #6 Volume of Alum suspension added to jar (mL) 0.400 0.800 3.00 6.00 12.0 Turbidity of Supernatant at 331 the end of settling time (FAU) 126 19 10 14 pH of supernatant at the end of settling time Alum dosage (mg/L) Ratio Alkalinity in Raw Water to Alkalinity Required 8.46 8.21 7.49 6.57 5.71 4. 26 0.00 8.38 16.8 62.9 126 252 13 6.6 1.6 1.1 0.66 O 50 mg/L O 17 mg/L 63 mg/L 8.4 mg/L Below is a Table showing the resuits from a Jar test conducted to determine the optimal dosage of alum to treat a specific surface water.
