At our company, we specialize in designing and manufacturing ultraviolet (UV) disinfection systems for air and water treatment. Our warehouse is fully stocked with key components—UV lamps, quartz sleeves, electronic ballasts, and hermetically sealed modules—allowing us to quickly fulfill orders of any size and respond to unique disinfection challenges.
The Project
We were contacted by a client managing ornamental fish ponds. The facilities included:
- Pond #1: 1,800 m³ volume, 450 m³/h filtration capacity, inhabited by 20 belugas (average weight ~50 kg).
- Pond #2: 800 m³ volume, 350 m³/h filtration capacity, populated with carp.
Both ponds were part of a closed-loop system using biofiltration and polypropylene storage tanks, where the UV modules needed to be integrated.
The Challenge
The primary issue was water "blooming" due to bacterial and algae overgrowth, which compromised both aesthetics and fish health. Prior use of ozonators proved unreliable—they required constant monitoring, had limited durability, and yielded unstable results. With valuable fish species in the system, a non-invasive and effective solution was essential.
Our Solution
We proposed a UV disinfection system using submersible modules installed within the intermediate polypropylene tanks, after the biofiltration stage. Water is treated with UVL Mod 19180 units before reentering the ponds. This configuration ensures effective microbial inactivation without direct exposure of fish to UV rays.
The use of amalgam UV lamps was intentional—they deliver high disinfection performance over a wide temperature range and offer greater energy efficiency and lamp lifespan compared to standard low-pressure alternatives.
Equipment Specifications
- Model: UVL Mod 19180
- Power consumption: 172 W
- UV output: 55 W (monochromatic 254 nm)
- Lamp type: Ozone-free amalgam
- Construction: Quartz sleeve, fluoropolymer-sealed head, silicone gaskets
- Ballast: L-220-1x200 with operational indicators
- Lamp lifespan: Up to 16,000 hours
- UV dose requirement: ≥ 40 mJ/cm²
- Supply scope: 24 modules for Pond 1, 16 for Pond 2
Implementation
Following a technical consultation, we calculated the required UV output based on water volume, filtration rate, and disinfection goals. A key condition was preserving the existing tank infrastructure. The modular design with threaded sealing allowed seamless integration into the current system.
Installation was swift—modules were mounted directly into the tanks using securing nuts, while ballasts were installed in a protected area. The system operates continuously, ensuring consistent UV exposure, prolonging lamp life, and minimizing the risk of microbial regrowth.
Client Benefits
- Solved algae bloom problem without chemicals or ozone, aligning with eco-friendly standards
- Minimal maintenance: quartz sleeves can be cleaned mechanically or chemically
- Fish safety ensured by placing the UV system outside the main habitat
- Fast delivery made possible by our well-stocked inventory
