The Well water ( a= NH3 mg/L , b=pH , c= GPM ) is acidified with 0.005% H2SO4 to pH 6.5 and then chlorinated with Ca(ClO)2 solution to obtain 0.5 mg/L residual chlorine (all coming from HClO) . With the data below compute : a) The volume and proportion of Ca(ClO)2 (70% available Cl2) with water so that the flow rate of 100 ml/min can last for 5 days (24 hrs per day, and use 200 liters drum). Note: The maximum percentage of Ca(ClO)2 should be 10%. Adjust the flow rate if necessary. b) The flow rate of 0.005% H2SO4 .
