CT Value definition
CT Value means a representation of the concentration of the disinfectant (C) multiplied by time in minutes (T) needed for inactivation of a particular contaminant. The concentration and time are inversely proportional; therefore, the higher the concentration of the disinfectant, the shorter the contact time required for inactivation. The CT value can vary with pH or temperature change so these values must also be supplied to allow comparison between values.
CT Value means a representation of the concentration of the disinfectant (C) multiplied by time in minutes (T) needed for inactivation of a particular contaminant.
CT Value means the contact time multiplied by the free disinfectant residual required to achieve adequate disinfection.

CT Value means a representation of the concentration of the disinfectant (C) multiplied by time in minutes (T) needed for inactivation of a particular contaminant. The concentration and time are inversely proportional; therefore, the higher the concentration of the disinfectant, the shorter the contact time required for inactivation.
CT Value means the product of the disinfectant contact time (T) in minutes and the concentration of the disinfectant residual (C) in mg/L measured at the end of the contact time. The product of these two parameters (CT) provides a measure of the degree of inactivation of specific organisms.
CT Value means the product of disinfectant residual and disinfectant CT. The required amount of CT needed is contained in the EPA Guidance Manual to the Surface Water Treatment Rule.
CT Value. In fumigation methods a dose is expressed by the CT value which is the product of concentration and time. cleaning than disinfection – it may be so strong that it poses a health threat and may require sealing or isolation of the cleaned space. This implies that decontamination is conducted by experts while disinfection using milder methods can be carried out routinely by regular staff.
