Bound chlorine typically refers to chloramines, which exist in three forms: monochloramine, dichloramine, and trichloramine.
The HOD™ (Hydro-Optic Disinfection) UV system removes bound chlorine through photolysis. Its medium pressure UV lamp emits a broad spectrum of UV wavelengths, including those specifically effective at breaking the chemical bonds in chloramine molecules. When exposed to this UV light, the bound chlorine dissociates into harmless compounds.
