Recycled Water Reuse

The recycling and utilization of municipal sewage or industrial wastewater can effectively alleviate the contradiction between water supply and demand, strengthen the sustainable support of water resources for the regional economy, and build a green and sustainable development system for regional economic circulation.

The safe reuse of reclaimed water, whether for landscape applications, municipal miscellaneous uses, or even higher-standard industrial process water or municipal indirect drinking water sources, requires ensuring its microbial and biotoxicological safety.

Efficient and reliable disinfection and advanced treatment technologies play a crucial role, especially when it comes to the targeted removal of pathogenic microorganisms and emerging contaminants such as pharmaceuticals, personal care products (PPCPs), and endocrine disrupting chemicals (EDCs).

Ultraviolet Disinfection Technology

Ultraviolet disinfection is applied to reclaimed water at the end of the distribution network and at the outlet of storage facilities.

For industrial reused water, reclaimed water is often used for cooling water replenishment and process water. Ultraviolet disinfection, due to its advantages of not introducing additional chemicals and avoiding corrosion, is used to control microbial growth in reused water systems.

For municipal reused water, reclaimed water is often used for waterscape replenishment and landscaping. Ultraviolet disinfection, due to its broad-spectrum and rapid bactericidal properties, is used for end-of-use disinfection to protect humans from viruses and pathogens.

Ozone Technology

Ozone contact tanks are often used for decolorization and partial disinfection in reclaimed water reuse, fully leveraging ozone's advantages in decolorization and deodorization.

Ozone-biological activated carbon (O3-BAC) is a common combined process for advanced reclaimed water treatment.

As a pre-oxidation method, ozone can increase the biodegradability of large organic molecules in water, providing a more readily available carbon source for microorganisms in the subsequent BAC filter, thereby enhancing the removal of dissolved organic matter and extending the adsorption life of the activated carbon.

Ultraviolet Advanced Oxidation Processes (UV-AOPs)

Special Source Drinking Water/High-Quality Recycled Water Treatment: UV-AOPs (particularly UV/H2O2) have attracted significant attention for the preparation of drinking water or the treatment of high-quality recycled water for indirect or direct drinking water reuse due to their ability to efficiently remove trace organic pollutants.

A combined process of microfiltration + reverse osmosis + ultraviolet advanced oxidation (UV/H2O2) treats wastewater.

UV-AOPs are used to remove trace pollutants such as nitrosamines (NDMA), drug residues, and endocrine disruptors from reverse osmosis product water, ensuring the safety of the reused water.

Specific Industrial Wastewater Advanced Treatment: For industrial wastewater containing high concentrations of recalcitrant organic matter, such as pharmaceutical wastewater, pesticide wastewater, chemical wastewater, and semiconductor industry recycled water, UV-AOPs are also considered a promising advanced treatment technology for improving the biodegradability of wastewater or directly removing toxic organic matter to meet reuse standards or more stringent discharge requirements.
