What is Disinfection?

Disinfection is a procedure that kills or inactivates the majority of microorganisms in wastewater, including almost all harmful species.

Disinfection and sterilization are similar procedures, but sterilization eliminates all micro-organisms, both hazardous and harmless. As a result, disinfection is a better option.

What is Wastewater disinfection?

Disinfection is the process of killing or controlling a large number of harmful organisms.It is often caused by cell wall erosion in microorganism cells, as well as changes in cell permeability, protoplasm, or enzyme activity (because of a structural change in enzymes).

Wastewater disinfection is typically the last step to regulate microbes and bacteria. Before wastewater is discharged into natural rivers, it is disinfected using a range of physical and chemical processes.Wastewater disinfection takes place after primary secondary and tertiary wastewater treatment. There are a variety of chemicals and techniques that can be used to disinfect wastewater, but none of them are universal.

The most extensively used disinfection technology is chlorination/de-chlorination. Variety of physical and chemical methods are used to disinfect wastewater. Ozonation and UV radiation are new technologies.

What is disinfection of water?

To decrease the impacts of organic material, suspended particles, and other impurities, disinfection is frequently the last step in the water treatment processes.

Ozone, ultraviolet radiation (UV), and chlorine are the principal ways for disinfecting water in very small (25-500) and small (501-3,300) treatment systems, similar to how they disinfect wastewater. Alternative disinfection techniques, such as chlorine dioxide, potassium permanganate, chloramines, and peroxone (ozone/hydrogen peroxide), have been less extensively utilized in very small water treatment systems.

Why is there a need for Disinfection in Water and WWTP?

Disinfection is one of the most important water treatment processes since it destroys microorganisms in drinking water. Micro-organisms are destroyed or deactivated,resulting in the termination of theirgrowth.  Disinfection can be attained by means of physical and chemical disinfectants.

Drinking water and wastewater disinfection are vital for public health protection. Disinfection should be used in all water and wastewater systems to eliminate or inactivate microorganisms (pathogens) that might cause diseases in humans and animals.

Mechanism of disinfection in water and wastewater treatment plants

Pathogenic organisms such as those that cause cholera, polio, typhoid, hepatitis, and a variety of other bacterial, viral, and parasite illnesses are protected from contact with disinfection of drinking water and wastewater.

Microorganisms are unable to reproduce as a result of the disruptions in cell function. The bacteria perish as a result of this. Organic stuff in the water or wastewater is also demolished by oxidizing disinfectants, resulting in nutrient deficiency.

The type of disinfectant used, the volume used, and the duration for which it is applied; the type and quantities of organisms present; and the physical and chemical features of the water all influence disinfection effectiveness.
