Disadvantages of UV Disinfection Lamps in Wastewater Treatment

No residual disinfection effect
UV is a physical disinfection method with no continuous bacteriostatic effect after treatment. Bacteria may regrow if secondary contamination occurs in pipelines.
Strongly affected by suspended solids and turbidity
Suspended solids block UV light and create a "shielding effect", greatly reducing disinfection efficiency. High-quality effluent is required.
Quartz sleeves are prone to fouling and need regular cleaning
Scale, iron, manganese and biofilm attach to sleeves and block UV light. Regular mechanical or chemical cleaning is necessary, increasing maintenance work.
Lamps have limited service life and require periodic replacement
UV intensity decays over time, so lamps must be replaced at rated life, resulting in consumable costs.
Relatively high energy consumption
Especially medium-pressure UV systems have high power consumption compared with chlorination.
Sensitive to UV Transmittance (UVT)
Low UVT shortens UV penetration and significantly weakens disinfection performance.
Cannot remove COD, ammonia nitrogen or organic pollutants
Only inactivates microbes; cannot degrade organic matter. It cannot replace biological or advanced treatment processes.
Higher initial capital investment
The upfront cost of UV equipment and electrical components (ballasts, etc.) is higher than traditional chlorination systems.
