Disinfection Design: dechlorination_stoichiometry
Wastewater disinfection design data from Metcalf & Eddy 5th Ed. Covers CT values (concentration × time) for log inactivation of bacteria, viruses, Cryptosporidium, and Giardia lamblia by chlorine, chloramine, chlorine dioxide, ozone, and UV radiation; specific lethality coefficients; physical/chemical properties of Cl2, ClO2, SO2, and O3; ozone Henry's law constants; HOCl ionization constants vs. temperature; chloramine activation energy; TDS contributions from breakpoint chlorination; dechlorination agent stoichiometry; chlorine dosage ranges for process applications; total coliform removal by treatment process; disinfection byproduct (DBP) compounds; ozone system energy consumption; and peracetic acid (PAA) commercial formulation specifications.
