To optimize the layout of the three lamps and the AOT module, the R&D team conducted over 50 fluid simulations and experiments, innovatively adopting a "triangular staggered surround" design. This maximizes the contact area between ultraviolet light and the photocatalyst, increasing hydroxyl radical generation by 40%, while avoiding dead zones in water flow, ensuring every drop of water undergoes double disinfection.
With increasingly stringent water quality standards, single disinfection technologies are insufficient to meet the demands of complex water treatment. Building upon traditional ultraviolet equipment, the team introduced AOT technology. After two years of research and development, they solved the problem of low synergistic efficiency between ultraviolet light and the photocatalyst, launching this 240-watt, three-lamp pipeline AOT ultraviolet sterilizer. This fills the market gap for deep disinfection of small and medium-sized pipelines, offering a 50% increase in disinfection efficiency and a 30% reduction in energy consumption compared to earlier products.

1. Q: Does AOT technology produce ozone?
A: No. The equipment uses specific wavelength ultraviolet light, with 185nm ultraviolet light accounting for only 10%. This 185nm ultraviolet light is absorbed by the photocatalyst to generate hydroxyl radicals, and will not produce ozone, thus avoiding any impact on water quality.
2. Q: Does the photocatalyst need to be replaced regularly?
A: No. The titanium-based titanium dioxide photocatalyst is a permanent coating and can maintain its activity for more than 8 years under normal operating conditions. Only periodic cleaning of surface contaminants is required.
3. Q: Does the equipment have requirements for the quality of the influent?
A: It is recommended that the influent turbidity be ≤3 NTU and residual chlorine ≤0.1 mg/L. Excessive turbidity will block ultraviolet light, and residual chlorine will inhibit the activity of the photocatalyst. Pre-treatment is necessary to meet these standards before the water enters the equipment.
4. Q: Can the disinfection intensity be manually adjusted?
A: Yes. The control box has a power adjustment function, allowing the output power to be adjusted within the range of 80%-110% according to water quality conditions, flexibly responding to water quality fluctuations.
5. Q: Does it need to be debugged after installation?
A: Simple adjustments are required. The manufacturer's technicians will set the optimal operating parameters based on the actual flow rate to ensure that the AOT reaction efficiency matches the UV dose. No complicated operation is required from the user.
"After installing this AOT UV sterilizer in the cleaning water pipes of our pastry factory, the microbial test pass rate increased from 95% to 100%, the product shelf life was extended by 3 days, and there were no chemical residues.
