An industrial wastewater stream of 15,000 gpd contains 100 mg/L of CN-. Determine the theoretical amounts (lb/day) of chlorine (as Cl2) required daily to pretreat cyanide to (1) cyanate (CNO-) and (2) nitrogen gas (N2).

NOW determine the theoretical amounts (lb/day) of Calcium hypochlorite, Ca(OCl)2 (70% pure), required daily to pretreat cyanide to (1) cyanate (CNO-) and (2) nitrogen gas (N2).
