How do UV sterilizers work?

The UV sterilizer utilizes a germicidal fluorescent lamp that produces light at a wavelength of approximately 254 nanometers (2537 Angstroms). The water with the bacteria/algae passes over the bulb (or around the bulb if a quartz sleeve is used) and is irradiated with this wavelength. As the light penetrates the bacteria/algae, it mutates the DNA (genetic material), preventing growth/multiplication of the organism.

What factors influence the effectiveness of UV sterilizers?

Size and type of organism: Theoretically UV radiation can kill viruses, bacteria, algae, and protozoa. In general, larger organisms, such as protozoa, require a higher dose of UV radiation than smaller organisms, such as bacteria. But there are also differences between various organisms of the same type: some bacteria are more resistant to UV radiation than others.

Power of bulb: The amount of UV light produced by the bulb is reflected in the wattage of the bulb. Bulbs with a higher wattage produce more UV light. The ability of the germicidal fluorescent lamp to produce UV light decreases with age, and in most cases, the bulb needs replacement every 6 months. UV light is best produced at temperatures of 104-110ºF; cooler temperatures will result in less output.

UV penetration: If the UV light can not penetrate the water, it will not be effective. Higher water turbidity will decrease penetration. UV sterilizers should be placed after the biological and mechanical filters so the water is as clear as possible when it enters the sterilizer. Salinity also affects penetration; UV light penetrates freshwater better than saltwater. Finally, cleanliness of the lamp or sleeve is important. If a film or mineral deposit covers the lamp or sleeve, the light will be partially or totally blocked. The distance of the lamp from the water also influences the effectiveness. UV light will only penetrate clear saltwater to a depth of 5mm.

Contact time: The longer the amount of time the water is being exposed to the UV light, the more killing power is available. The contact time, sometimes referred to as "dwell time," is influenced by flow rate of the water: slower flow rates increase contact time. The length of the bulb also affects the contact time; with a longer bulb, the water is in contact with the UV light for a longer period of time. Another variable to consider is the turnover time (amount of time required to have the entire volume of water in the aquarium pass through the sterilizer). Since the "sterilized" water constantly mixes with the water in the aquarium as it returns, it is impossible to "sterilize" all the water in the aquarium. That would only be 

Working principle:

The device adopts a special high strength non ozone ultraviolet sterilizing lamp and stainless steel barrel body odor whose inner wall specially treated by micro carbon martensite, outer side of the barrel body with a special polishing processing, then the pretreated water flows in the tube, it will receive enough line volume of ultraviolet irradiation 253.7nm, which shows excellent germicidal efficacy, but also effectively reduces the influence on ultra pure water.

Optimal service condition:

As UV is a short- wavelength light wave, it has low radiant energy and weak penetrating power and can only kill the microorganisms it directly radiates on. Therefore, in order to enhance the bacteria-killing efficiency and ensure the security of drinking water, the incoming water into the sterilizer must meet the following standard, (and if exceeding the following standard, the killing efficiency may be affected).
