Ozonation in drinking water treatment:

Ozonation is a process used in water treatment for disinfection and oxidation. It involves the use of ozone gas, which is a powerful oxidant and disinfectant. When ozone is added to water, it reacts with organic and inorganic compounds, micro-organisms and other contaminants, breaking them down and removing them from the water.

Removal of micro-organisms:

One of the main benefits of ozonation in drinking water treatment is the removal of micro-organisms. Ozone is a powerful disinfectant that can kill bacteria, viruses, and other pathogens. It works by breaking down the cell walls and membranes of these micro-organisms, rendering them inactive and unable to reproduce.

Ozone is particularly effective against protozoa, which are larger micro-organisms that can be resistant to other disinfectants like chlorine. Ozone can also remove the taste and odour associated with some micro-organisms, making the water more palatable.

Other benefits of ozonation:

In addition to removing micro-organisms, ozonation can also provide other benefits in drinking water treatment, including:

- Removal of organic and inorganic compounds: Ozone can break down organic and inorganic compounds in the water, including pesticides, herbicides, and other contaminants. This can improve the taste and odour of the water and reduce the risk of health problems associated with these contaminants.

- Reduced disinfection by-products: When chlorine is used for disinfection, it can react with organic compounds in the water to form disinfection by-products (DBPs). These DBPs can be harmful to health in high concentrations. Ozonation can reduce the formation of DBPs, making the water safer to drink.

- Improved colour and clarity: Ozone can also improve the colour and clarity of the water by breaking down and removing organic compounds that can cause discolouration and turbidity.

Conclusion:

In conclusion, ozonation is an effective process for removing micro-organisms and other contaminants from drinking water. It can improve the taste, odour, colour, and clarity of the water, and reduce the risk of health problems associated with contaminants and disinfection by-products.
