Since ultraviolet light was first used for drinking water disinfection in 1910, this technology has been widely applied in the food and beverage industry. UVC ultraviolet light (wavelength 200–280 nm) can effectively inactivate microorganisms such as bacteria, viruses, fungi, algae, and protozoa wit

UV disinfection uses short‑wavelength UV‑C light to penetrate microorganisms in water and damage their DNA or RNA, so they can no longer reproduce or cause infection. This purely physical process adds no chemicals and does not change the taste, odor, or mineral content of the water, making it widely used for drinking and industrial water treatment.

In closed-loop water systems—such as Recirculating Aquaculture Systems (RAS), cooling towers, hot water circulation, industrial cooling loops, aquariums, swimming pools, or laboratory/pharmaceutical ultrapure water recirculation—water is continuously cycled rather than frequently discharged or replenished. This conserves resources but increases risks: accumulation of organics (e.g., feed, waste, nutrients) leads to eutrophication (excess nitrogen/phosphorus), stagnation, warmth, and light exposure in some setups, promoting proliferation of pathogens (e.g., Legionella, Pseudomonas aeruginosa, viruses) and algae. UV recirculating water purification integrates UVC LED water disinfection modules directly into the recirculation loop for continuous, chemical-free treatment.

UV water treatment is a safe, chemical-free method that effectively kills bacteria, viruses, protozoa, and algae, ensuring clean and pathogen-free water.
