ABSTRACT
In the United States, regular disinfection practices were used in Chicago and New Jersey by 1908. Disinfection is a process whose objective is the destruction or inactivation of pathogenic microorganisms. Turbidity or cloudiness is caused by the suspended solids present in water, as has been discussed earlier. It has been demonstrated to interfere with disinfection because the suspended particles which are responsible for the turbidity surround and shield microorganisms. Wastewater disinfection is the destruction or inactivation of pathogenic organisms and is carried out to minimize public health concerns. Destruction is the physical disruption or disintegration of a pathogenic organism, whereas inactivation is the removal of a pathogen’s ability to infect. Viruses are obligate parasites and can only reproduce by dominating the internal processes of host cells and using the host’s resources to produce more viruses. Viruses are very small particles whose protein surface charge changes in magnitude and sign with pH.
