In the field of ultraviolet sterilization, Coospider UV Filter uses short-wave UV-C light with a wavelength of 253.7 nanometers to irradiate water flow and achieves sterilization by destroying the DNA structure of microorganisms. Experimental data show that when its radiation dose reaches 30,000 μW·s/cm², it can inactivate 99.9% of common aquatic pathogenic bacteria (such as Aeromonas hydrophila and Flavobacterium columnum), and the bacterial concentration drops from the initial 10⁶ CFU/mL to below 10² CFU/mL, meeting the requirements of the ISO 15587 water quality safety standard. In the 2023 International Aquarium Exhibition case, this equipment was applied to a 500-liter aquaculture system, reducing the incidence of fish diseases from 28% to 5% while maintaining the ammonia nitrogen concentration stable within the safety threshold of 0.2mg/L.
This device is compatible with water body specifications ranging from 80 to 300 liters. The flow rate range is designed to be 200 to 500 liters per hour, ensuring that aquatic organisms are exposed to ultraviolet rays for at least 20 seconds, reaching the critical lethal energy threshold. The power consumption is only 8-15W (the annual electricity bill is about 30 yuan when operating for 8 hours a day), which saves 60% of the cost of chemicals compared with the chemical disinfection solution (an average annual budget savings of 120 yuan). The 2021 report of the German Aquatic Animal Research Center pointed out that under a constant temperature of 25°C, after the UV Filter system was in operation for six months, the detection rate of Vibrio in water decreased by 94%, and it effectively maintained the dissolved oxygen level above 6.8mg/L, reducing the risk of fish asphyxiation due to oxygen deficiency.
From the perspective of long-term maintenance, this equipment adopts quartz sleeve isolation technology to extend the lifespan of the UV lamp to 18 months (standard usage cycle), with a replacement cost of less than 150 yuan. The annualized maintenance cost only accounts for 15% of the overall filtration system investment. Compared with the control group that did not use UV technology, the feedback from users of this device showed that the fish mortality rate decreased by 12 percentage points (from an average annual rate of 15% to 3%), and the antibiotic usage was reduced by 40 grams per year. In 2022, a survey by the American Fisheries Association confirmed that the NTU value of water clarity in fish tanks equipped with this device has remained stable at below 0.5 for a long time (the industry safety upper limit is 1.0 NTU), significantly reducing the incidence of fish ulcers.
From the perspective of return on investment, taking a 150-liter fish tank scenario as an example, the initial purchase price of the equipment is approximately 400 RMB. However, by reducing the loss of fish (calculated at an average unit price of 50 RMB) and medical costs, the investment payback period is about 14 months. Operational data from the Vancouver Aquarium in Canada shows that this solution has reduced the cost of water treatment per cubic meter by $18.7 per year and increased the utilization rate of recycled water by 22%. Certified by the Intertek laboratory in the UK, the sterilization efficiency of this UV Filter remains stable at 96% even when the water temperature fluctuates by ±0.5℃, meeting the biosafety standards of the EU CE certification.
