UV Sterilizer

A UV sterilizer is a device that uses ultraviolet (UV) light to clean or disinfect water. UV sterilizers treat water for drinking, swimming, and other purposes. They are also used in hospitals and different settings where cleanliness is important. UV sterilizers work by killing bacteria and other microorganisms in water.

If you’re looking for a way to cleanse your home or office of harmful bacteria and germs, you may want to consider investing in a UV sterilizer. UV sterilizers use ultraviolet light to kill bacteria and viruses on surfaces. While UV sterilizers are most commonly used in healthcare settings, they can also be used in homes and businesses. Here’s what you need to know about UV sterilizers.

What does a UV sterilizer do?

A UV sterilizer regulates infections by stopping the spread of microorganisms from one fish/coral/invertebrate to a different one through the water. It’s also utilized in pond applications to regulate free-floating algae. When operated correctly, free-floating microorganisms will be killed by UV light. Note that the organisms must be within the water that flows to the UV sterilizer. The UV light has no residual effect and can not kill organisms attached to fish (e.g., adult stage of ich) or rocks (e.g., algae).

How do UV sterilizers work?

The UV sterilizer utilizes a germicidal lamp that produces light at a wavelength of roughly 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. Because the light penetrates the bacteria/algae, it mutates the DNA (genetic material), preventing the growth/multiplication of the organism.

What factors influence the effectiveness of UV sterilizers?

– Size and sort of organism: Theoretically, UV radiation can kill viruses, bacteria, algae, and protozoa. Generally, larger organisms, like protozoa, require a better dose of UV radiation than smaller organisms, like bacteria. But there also are differences between various organisms of an equivalent type: some bacteria are more immune to UV radiation than others.

– Power of bulb: the quantity of UV light produced by the bulb is reflected within the wattage of the bulb. Bulbs with a better wattage produce more UV light. The power of the germicidal lamp to supply UV light decreases with age, and in most cases, the bulb needs replacement every 6 months. UV light is best produced at temperatures of 104-110°F; cooler temperatures will produce less output.

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

– Contact time: The longer the time the water is exposed to the UV light, the more killing power is out there. The contact time, sometimes called “dwell time,” is influenced by the flow of the water: slower flow rates increase contact time. The length of the bulb also affects the contact time; with an extended bulb, the water is in touch with the UV light for an extended period of your time. Another variable to consider is the turnover time (the amount required to possess the whole volume of water within the aquarium undergoing the sterilizer). Since the “sterilized” water constantly mixes with the water within the aquarium because it returns, it’s impossible to “sterilize” all the water within it. That might only be possible if all the water was removed, sterilized, and then returned to the aquarium on one occasion. This might end in sterilized water but would raise havoc with the aquarium inhabitants! Calculating turnover time is mathematically difficult but is often approximated with the following formula:

– Temperature: UV light is best produced at temperatures of 104-110°F; cooler temperatures will produce less output. Quartz sleeves help insulate the bulb from the cooler aquarium water, thus maintaining a better UV output.

Viruses = 15,000

Algae = 22,000 — 30,000

Protozoa = 90,000

– Note: These are generalities; some specific organisms in these groups may require more or less dose than indicated.

Which systems should UV sterilizers be used, and what are the benefits?

A UV sterilizer could also be utilized in any aquarium; however, its value may make it impractical in smaller aquariums (less than 24 gallons). UV sterilizers are most helpful in multiple tank systems with a standard filter. A single tank system they’re beneficial in controlling the spread of an infectious disease if one occurs. This is often very true in heavily stocked tanks and people with large amounts of live rock and corals that would make catching and isolating a diseased fish difficult or the utilization of certain medications contraindicated. Disease control is particularly important when adding new fish to a longtime aquarium since 98% of hobbyists don’t use a quarantine aquarium.

UV sterilizers are one of the simplest ways to regulate free-floating algae in ponds, allowing the pond owner to ascertain and luxuriate in the fish. The UV sterilizer also will kill free-floating bacteria within the pond water.
What are the restrictions and potentially harmful side effects of UV sterilizers?

UV sterilizers aren’t a replacement for permanent biological and mechanical filtration, regular water changes, and proper control of the organic process. A UV sterilizer should be considered as a policy.

UV sterilizers will be ineffective against string algae or other nuisance or disease-causing organisms that aren’t free-swimming within the water.

While the UV sterilizer will usually not harm, it shouldn’t be used when cycling the aquarium because it may kill beneficial bacteria before attaching to the bio-media or gravel.
What are the restrictions and potentially harmful side effects of UV sterilizers? (continued)

Many medications are often “denatured” by UV light. Therefore, the sterilizer should be turned off when using drugs, especially chelated copper treatments. The UV light will “break” the bond of the chelating agent, and therefore the aquarium will have a sudden, lethal concentration of ionic copper.

The UV sterilizer is often wont to control parasites, but the flow required is so slow that it’s somewhat impractical on larger aquariums unless larger (40W+) UV systems are used.

UV sterilizers can heat the water because it passes through, especially if the unit is larger than necessary for the tank size. A chiller could also be necessary to stay in the aquarium water at an acceptable temperature.

What sorts of UV sterilizers are available?

The sorts of UV sterilizers relate to their orientation when in use (horizontal or vertical) or their position within the water flow (in-line or hang-on). All vertical units must be used vertically, while several horizontal (Rainbow) units are often used horizontally. Some styles are often used in-line or persisted at the rear of the tank. Specialized units are designed to be utilized in outdoor/pond applications.

A newer UV sterilizer called the “double helix,” increases the contact time between the water and, therefore, the UV light because the water makes a double spiral skip the tube.

Models may or might not have a quartz sleeve. Those with a sleeve are sometimes called “dry bulbs.” Coldwater systems must have a quartz sleeve for the right UV light output. A sleeve makes periodic cleaning and bulb replacement easier.

According to Robert Fenner, a well-known aquarist, author, and speaker, features of a natural UV sterilizer include:

– A separate (remote) ballast unit will be positioned in a place free from heat and water damage

– An indicator light to see for “on” operation

– An “automatic on” feature to show the UV unit back on in the event of a short-lived power loss

– Couplings that are easily fitted to your system

– A quartz or Teflon sleeve at little or no additional cost

– All noncorrosive water-contact surfaces

– Acceptable guarantees and warranties

How is the correct size of a UV sterilizer determined?

This is about the sole “complicated” part of utilising a sterilizer. The UV sterilizer must be matched to the right flow for correct use to ensure an efficient “kill dose” for the organisms you want to eliminate. This flow must be compared to the aquarium’s dimensions to ensure the right number of “turn-overs” of the water. Most manufacturers will provide a table recommending the utmost aquarium size and appropriate flow for every model they create. When comparing manufacturers, realize ratings may differ on whether or not they take into account the following:

– Bulb efficiency: Some use one hundred pc efficiency, others a lower efficiency (e.g., 60 per cent observed towards the top of the bulb life)

– Organism to be killed: Bacteria/algae or protozoa

– Water clarity: Clear or turbid

– Transmission loss through the quartz sleeve

These differences make it very difficult to supply general rules of thumb. Ask the manufacturer if you’re unsure of how the ratings are calculated.

How may be a UV sterilizer installed?

The UV sterilizer should be the last piece of the kit within the water filter system before the water is returned to the aquarium. Biological and mechanical filters and any chemical filter or device within the system should precede it. Follow the manufacturer’s directions on installation. Most units use hose barb connectors to connect to the acceptable pump or are designed to permit add-on connectors as a PVC slip fit or hose barb attachment.

What is the right maintenance schedule for UV sterilizers?

The quartz sleeve will be checked monthly, removed, and cleaned with lotion. Some larger UV sterilizers have wiper mechanism units installed for easier maintenance.

For most units, the UV bulb will get replaced after 6 months of continuous use. However, this point may vary, so follow the manufacturer’s recommendations. When installing or changing a bulb, never look directly at the bulb when the unit is turned on. Doing so may result in permanent damage to your eyes. (The injury can occur without you feeling any discomfort.)

Always disconnect the unit from the electricity when performing maintenance to guard against possible shock. When turned on, the bulb becomes especially hot in the air, and submerging it in water may cause it to interrupt.
