Advanced STP with UV & Ozonation for Water Recycling

Advanced Sewage Treatment Plants (STPs) with UV and Ozonation are cutting-edge wastewater treatment systems designed for highly efficient water recycling by ensuring superior disinfection and oxidation of contaminants.

Key Features of Advanced STP with UV & Ozonation:

• High-Quality Disinfection:

  • UV light damages microbial DNA, effectively inactivating bacteria, viruses, and other pathogens without harmful disinfection by-products.

  • Ozonation is a powerful oxidant that breaks down organic pollutants, eliminates color, odor, residual pesticides, and disinfects water by destroying bacteria and viruses more completely than chlorine.

• Advanced Oxidation Process (AOP):
  Combination of ozone and UV produces hydroxyl radicals (OH∙ OH ∙) that degrade even hard-to-remove pollutants and organic molecules, ensuring exceptionally clean water.

• Process Integration:

  • Secondary treated water is filtered and then subjected to UV and ozone treatment as part of tertiary treatment stage.

  • Ozonation tanks and UV reactors can be integrated seamlessly into existing STPs or designed as part of new installations.

• Environmental and Health Benefits:

  • Eliminates chlorine use, thus avoiding toxic chlorine residuals and disinfection by-products like trihalomethanes (THMs).

  • Oxygen content of water improves after ozonation, benefitting aquatic ecosystems if discharged.

  • Effective against emerging contaminants such as pharmaceuticals and personal care products.

• Applications:

  • Commercial complexes, residential townships, hospitals, and hotels requiring safe, clean, and reusable water.

  • Industries and municipalities looking for sustainable water reuse options.

• Use Cases:

  • Flush water recycling, landscaping irrigation, cooling tower makeup water, and other non-potable industrial uses.

• Safety and Automation:

  • Systems typically include ozone gas monitoring, residual ozone destructors for safe operation, automatic control panels with real-time monitoring.

• Advantages:

  • Chemical-free and environmentally friendly.

  • Low operating costs compared to chemical disinfection long term.

  • Enhances overall effluent water quality to meet stringent discharge and reuse standards.
