1) (20) Carbon adsorption is to be used to treat 4 ppm of TCE in 80,000L/hr...
2.(40 pts) You are to design an activated carbon adsorption system for treatment of drinking water containing Chlordane, a termite pesticide that contaminates Honolulu soils and leaches into the drinking water. The Freundlich isotherm constants (Table 13.2) and K = 190 (mg/g)(L/mg)', and 1/n = 0.33. The water to be treated has a chlordane concentration of 0.1 mg/L. Since the MCL is 0.002, you must design for an equilibrium concentration of 0.0005 mg/L. The flow rate is 1 MGD. Assume...
The Freundlich isotherm constants (Table 13.2) and K = 190 (mg/g)(L/mg)1/n, and 1/n = 0.33. The water to be treated has a chlordane concentration of 0.1 mg/L. Since the MCL is 0.002, you must design for an equilibrium concentration of 0.0005 mg/L. The flow rate is 1 MGD. Assume a carbon density of 30 lb/ft3, and a typical carbon column depth of 10 ft. The carbon contractors must provide one year of treatment before new carbon is needed. Specify the...
Acetaminophen is a medication used to treat pain and fever and contains Carbon, Hydrogen, Oxygen, and Nitrogen. Combustion analysis of a 15.0-mg sample of acetaminophen produced 8.10 mg of water. What is the percent by mass of Hydrogen in acetaminophen? O 4.4% O 12.0% O 7.5% 0 3.0% O 6.0% Which of the following substances form both ions and molecules in solution ? CH3OH Li2CO3 OHCIO4 Sr(OH)2 H3PO4 The pH of a solution of barium hydroxide is 12.53. How many...
