Applicable objects: All disinfection equipment using C-band (200–280 nm) ultraviolet as the sterilization factor.
Covered scenarios: Water disinfection, air disinfection, and surface disinfection.
Fields:
Municipal water supply, wastewater treatment, secondary water supply
Medical facilities (operating rooms, ICUs, sewage)
Food processing and beverage production
Swimming pools, hot springs, aquaculture
Public places, households, etc.
Effect: Mandatory nationwide; serves as the legal basis for product launch, inspection and supervision.
Applicable objects: UV disinfection equipment dedicated to urban water supply and drainage (including medium-pressure lamps).
Covered scenarios:
Drinking water
Municipal wastewater treatment plant effluent
Reclaimed water reuse
Effect: Recommended, but widely applied in bidding, design and acceptance of municipal projects.
Applicable objects: UV disinfection devices in the environmental protection and water treatment industry.
Covered scenarios:
Industrial wastewater, municipal sewage
Reclaimed water, landscape water
Swimming pools, aquaculture and other water-related environmental protection projects
Effect: Technical specifications and acceptance criteria within the industry; not mandatory by the state, but often required in project bidding.
Applicable objects: Water treatment market (municipal, industrial, food, swimming pools, aquaculture, etc.).
Covered scenarios:
Large and medium-sized water plants, wastewater treatment plants
Industrial cooling circulating water, chemical wastewater
Food and beverage production lines
Swimming pools, hot springs, aquaculture
