  • What are the different methods of water disinfection?
  • Disinfection has been proposed by different methods including exposing the water to sunlight, boiling, using silver, copper, chlorine, peroxide, bromine, ozone, and ultraviolet radiation. Each method has some advantages or limitations. Various water disinfection options have been depicted in Fig. 1.
  • What technologies are used for disinfection of water?
  • Conventional Technologies Conventional technologies are the most widely used processes for disinfection of water. They are classified into chemical processes, including chlorine, chlorine dioxide, ozone and peracetic acid. In addition to chemical disinfectants, UV radiation has been used for many years for disinfection in wastewater treatment.
  • Can disinfection technologies be used in drinking water treatment plants?
  • With the use of chemical disinfectants, residues of the compounds used and/or their DBPs can be found in the treated water that may have a toxic effect on humans and the aquatic environment. Aim of this work is exploring the disinfection technologies applied in drinking water treatment plants (DWTPs) and in wastewater treatment plants (WWTPs).
  • Which Disinfectant is used in water treatment?
  • Action Mechanisms Chlorine is the most widely used disinfectant for the inactivation of waterborne pathogens in water treatment in the form of gaseous chlorine, chloramines and, above all, sodium hypochlorite [ 15 ]. The influencing factors are temperature, pH and organic content in the water.
