Problem 1 Estimate the daily carbon utilization to remove chlorobenzene from 1 million$ 30.00

Problem 1 Estimate the daily carbon utilization to remove chlorobenzene from 1 million gal/day of groundwater saturated with chlorobenzene. Assume a chlorobenzene concentration of 5 mg/L is acceptable for discharge to a POTW.

Problem 2 Provide a preliminary design of a carbon adsorption system (i.e. the height of the adsorption zone, the number and size of column units, and the daily carbon usage rate) for the removal of 2,4,6- trichlorophenol from 250,000 gal/day of water. The following data are provided: Bohart-Adams model: a = 2.3 days/ft; b = -10 days (for the 90% removal line) in laboratory tests where trichlorophenol concentration was reduced from 395 mg/L to 10 mg/L at a loading of 4 gal/(ft2 ∙min) using laboratory columns with the following specifications: 2.3 m column length, 0.051 m column diameter, and 0.5 L/min flow rate. The adsorption zone was 19 ft. Assume that the unit weight of carbon is 481 kg/m3 .

Problem 3 A plating waste with a flow of 40,000 gal/day contains 274 mg/L of NaCN. Determine the amounts of chlorine as Cl2 and NaOH required to oxidize the cyanide to CO2 and N2.

Problem 4 A waste contains 150 mg/L of copper at a flow rate of 75 L/min. Determine the amount of sodium borohydride required to treat this waste.Category: BusinessGeneral Business
