8.2 Disinfection

Disinfection is used to eliminate the infectious or pathogenic agent or agents present.  A disinfectant is selected according to the specific infectious agent known or suspected to be present, as each chemical compound has a selective germicidal activity.  Liquid disinfectants are available under a wide variety of trade names.  The more active a compound is, the more likely it is to have undesirable characteristics such as corrosivity.  No liquid disinfectant is equally useful or effective under all conditions and for all viable agents.  The most practical use of liquid disinfectants is for surface decontamination.  At sufficient concentrations they can be used as decontaminants for liquid wastes prior to disposal in the sanitary sewer.
