Chlorination stands as a widely adopted method for water disinfection. This process involves introducing chlorine into the water to neutralize harmful microorganisms, rendering it safe for consumption. The method effectively prevents waterborne diseases and plays a crucial role in ensuring public health.

    Effective against a wide range of microorganisms – such as Legionella.

    Provides residual protection throughout the distribution network.

    Economical and adheres to industry standards.

    Potential generation of disinfection by-products.

    May contribute to taste and odour issues in water.

    Requires careful handling due to its hazardous nature.

    UV Disinfection

    UV disinfection relies on ultraviolet light to deactivate microorganisms. This method is gaining popularity due to its chemical-free nature and its ability to effectively neutralize bacteria and viruses.

    Chemical-free method of disinfection.

    Efficiently neutralizes bacteria and viruses.

    Leaves no chemical residues in treated water.

    Effectiveness relies on achieving proper contact time.

    Regular maintenance is essential for sustained performance.

    Initial installation costs can be relatively higher.


    Ozonation employs ozone gas to eliminate contaminants from water. This method is known for its potent disinfection properties and effectiveness against organic compounds.

    Offers robust disinfection capabilities.

    Generates fewer disinfection by-products compared to other methods.

    Effectively eliminates taste and odour issues in water.

    Involves complex installation and ongoing maintenance.

    Ozone has a short half-life, necessitating precise contact time control.

    Does not provide residual protection in water distribution networks.

    Water Treatment - Making an Informed Choice

    Selecting the most suitable water treatment method depends on factors such as water quality, intended usage, and budget constraints. Chlorination offers residual protection, UV disinfection provides chemical-free treatment, and ozonation ensures effective disinfection. Consider these factors carefully when making your decision.
