Which range corresponds to the ORP range associated with maximum disinfectant effectiveness?

Disinfection effectiveness rises with the oxidizing power of the solution, which ORP measures. Higher ORP means stronger oxidants are available to inactivate microorganisms, so you want a level that provides robust disinfection without being impractically extreme. The range from 600 to 900 mV sits in that strong, practical oxidizing zone where disinfection is maximized under typical conditions. Lower ranges lack sufficient oxidizing power to reliably kill microbes, while the 900–1200 mV range is unusually high for routine disinfection and isn’t necessary for additional benefit.
