- Chemical-free microbial control
- Horizontal inline reactor design
- Corrosion-resistant UPVC housing
- 30–300 m³/h flow range
- Replaceable UV-C lamps
How It Works
UV-C Photochemical Disinfection Process
The UV sterilizer uses ultraviolet-C light to treat microorganisms in the circulating water flow. UV-C energy affects the DNA structure of microorganisms, reducing their ability to reproduce and helping maintain better microbial control within the RAS environment.
UV-C Exposure
Water passes through the UV lamp chamber and is exposed to UV-C irradiation.
Microbial Reduction
UV energy affects microorganism activity and reduces biological contamination.
Treated Water Returns to RAS
Disinfected water continues through the circulation system and returns to fish tanks.

RAS Integration
UV Sterilizer Position in Complete RAS System
A typical YUTANK RAS configuration places the UV sterilizer after mechanical filtration and biological treatment, providing additional microbial control before treated water returns to the fish tanks.
The UV Sterilizer works together with mechanical filtration, biological filtration and degassing equipment to maintain overall RAS water quality. As part of a complete RAS system, the UV sterilizer is coordinated with upstream solids removal, biological treatment, gas management and oxygenation.

FAQ
FAQ About UV Sterilizer
01 What does a UV sterilizer do in an RAS system?
A UV sterilizer uses ultraviolet-C light to reduce microorganisms in circulating water and provides additional microbial control in recirculating aquaculture systems.
02 Where should a UV sterilizer be installed in an RAS?
UV sterilizers are commonly installed after mechanical filtration and biological treatment equipment, before treated water returns to fish tanks.
03 Can UV sterilization replace biological filtration?
No. UV sterilization mainly controls microorganisms. Biological filtration is required for ammonia and nitrite conversion in RAS systems.
04 What material is the UV sterilizer made from?
The reactor body is manufactured using UPVC material, providing corrosion resistance for aquaculture water treatment applications.
05 How long do UV lamps last?
UV lamp replacement intervals depend on the selected lamp model and operating conditions. Follow the supplied lamp specifications and maintenance guidance.
