Advanced water treatment technology
Advanced water treatment technology
Advanced water treatment refers to a technical system that uses physical, chemical and biological enhancement processes to achieve deep removal of pollutants. Its core goals are:
Targeted pollution removal
Microorganisms: Inactivation rate > 6-log (Cryptosporidium/virus)
Organic pollutants: TOC removal rate ≥ 95% (including pesticide/drug residues)
Inorganic pollutants: heavy metal ion interception rate> 99.9%
Emerging pollutants: PFAS/PFOA removal efficiency ≥ 90%
Core Technology Matrix
Technology Category Representative Process Key Performance Indicators
Membrane separation technology Reverse osmosis (RO) Desalination rate >99.8%
Nanofiltration (NF) Divalent ion retention > 95%
Advanced oxidation processes (AOPs) Ozone/ultraviolet (O₃-UV) Hydroxyl radical yield 5×10⁻⁴ mol/J
Electrochemical oxidation COD degradation rate 0.8kg/(m³·h)
Adsorption technology Activated carbon (GAC/PAC) Iodine value ≥1000mg/g
Ion exchange chelating resin Heavy metal adsorption capacity 5meq/g
Application scenarios and standards
Drinking water plants: meet the microbial limit values of the 5th edition of the WHO Guidelines for Drinking Water Quality
Wastewater Reclamation Plant: Meets ISO 20760 Standard for Industrial Recycled Water
Semiconductor ultrapure water: resistivity ≥18.2 MΩ·cm (ASTM D5127)
Sustainable Value
The wastewater reuse rate increased to 75% (3 times higher than the traditional process)
Energy recovery rate>35% (membrane concentrate energy recovery system)
