How many pounds per day (lbs/day) of lime and soda ash need to be delivered daily to a plant treating groundwater with the following characteristics (do not worry about adding any safety factor, even though you would in the real world): Calcium Carbonate Hardness (CaCH) = 200 mg/L as Calcium Carbonate Magnesium Non-Carbonate Hardness 100 mg/L as Calcium Carbonate (Use soda ash; carbon dioxide is not an option) Alkalinity= 200 mg/L as Calcium Carbonate Flow Treated - 10 MGD The answers are expressed in units of lbs/day with lime first followed by soda ash 4,800 and 3,100 O 22,600 and 31,000 O 15,000 and 7,400 O 18,500 and 8,800

Question
Transcribed Image Text:How many pounds per day (lbs/day) of lime and soda ash need to be delivered daily to a plant
treating groundwater with the following characteristics (do not worry about adding any safety
factor, even though you would in the real world):
Calcium Carbonate Hardness (CaCH) = 200 mg/L as Calcium Carbonate
Magnesium Non-Carbonate Hardness = 100 mg/L as Calcium Carbonate (Use soda ash; carbon
dioxide is not an option)
Alkalinity= 200 mg/L as Calcium Carbonate
Flow Treated = 10 MGD
The answers are expressed in units of lbs/day with lime first followed by soda ash
O 4,800 and 3,100
O 22,600 and 31,000
O 15,000 and 7,400
O 18,500 and 8,800
