Domestic Wastewater and UV Disinfection. Most domestic wastewater treatment facilities in Florida must meet either "basic disinfection" (applies to most surface water discharges) or "highlevel disinfection" (applies to many reuse systems). These two levels of disinfection are described in Rule ,
What is water disinfection? Water disinfection means the removal, deactivation or killing of pathogenic microorganisms. Microorganisms are destroyed or deactivated, resulting in termination of growth and reproduction. When microorganisms are not removed from drinking water, drinking water usage will cause people to fall ill.
