A new treatment conventional plant will use ozone as the primary disinfectant and chloramine (NaOCl+NH3) as the secondary disinfectant. Design the disinfection system given: Water analysis: Constituent Concentration TOC 10-20mg/L Bromide 0.010mg/L Turbidity 10-500NTU Total coliforms 100-1,000/100mL Giardia cysts 5/100L Virus 2/100L Cryptosporidium oocysts >3.0/L pH of the water entering the contact chamber=7.0 Winter water temperature will be 5°C Ozone trial dose=2.5mg/L Second-order rate constant of 6.0x10L/mg-min Superior performance contact chamber Sodium hypochlorite and ammonia (g/min will be used to achieve a dichloramine=1.6mg/L a. What log inactivations are required? Make a table of microorganism, reference (cite the tables that you use for each microorganism), total log inactivation required, treatment credits, and disinfection log inactivations for Giardia, viruses, and Cryptosporidium. b. What are the Ct requirements for Giardia, viruses, and crypto during disinfection Cite the tables that you use. Which Ct requirement governs? c. What is the time required for 90% of the flow to be exposed to the disinfectant d. What is the hydraulic residence time? e. Calculate the decay through each cell of the ozone contact chamber and confirm that sufficient Ct is provided in cells 2 though 10 combined, or recommend a different dose and/or time. Provide your Excel calculations. f. Propose dimensions (L x W x H) for the ozone contact chamber. Explain your reasoning. g. What is the dichloramine concentration in mol/L? h. What is the sodium hypochlorite (NaOCl) feed rate to achieve 1.6 mg/L NHCl? i. What is the ammonia (NH3) feed rate to achieve 1.6 mg/L NHCl?
