Een UVC-filter is vooral bedoeld voor vijvers die langdurig groen en troebel zijn en waar een behandeling met een anti-zweefalgmiddel te weinig effect heeft. Door plaatsing van een UVC-filter kunnen vijvers die al zeer lang troebel zijn, weer kraakhelder gemaakt worden.
Om een UVC-filter te kunnen plaatsen, moet er een pomp aanwezig zijn in de vijver die vijverwater langs het filter pompt. Een goed aangelegde en ingerichte tuinvijver heeft geen UVC-filter nodig om helder te blijven.
In veel vijvers wordt hetA biologisch evenwichtA dat de vijver helder houdt echter regelmatig verstoord. USHIO Germicidal lamps are Low-Pressure Mercury-Arc lamps that emit radiation peaking at 253.7nm(UVC). Known as Ultraviolet Germicidal Irradiation (UVGI), this new method employs light in the ultraviolet wavelength (400nm and 10nm — shorter than visible light, longer than X-rays).


Turns out, two specific frequencies of 265nm and 185nm, do most of the damage, penetrating cellular walls and disrupting DNA replication (dimerising adjacent pairs of thymine, specifically) which in turn prevents the cell from replicating or repairing itself, rendering it harmless if not outright dead. There are two primary means of producing UV light in these two frequencies — continuous mercury vapour UV lamps and pulse xenon UV.
In hospitals, surgical instruments and operating theatres aren’t the only vectors for disease transmission, patients are just as likely to pick up a secondary infection from something in the recovery room. In addition to copious amounts of hand sanitizer and bleach washes, hospitals are now turning to devices like the UV emitter from Xenex Healthcare Services. At this point, UV disinfection remains a supplementary process to chemical cleaning methods, however, the market for these devices is growing and is expected to grow from $US30 million to $US80 million in the next three years.
The ozone these things create is going to significantly shorten the lifespan of everything in the room! Interesting fact, UV is actually universally effective at causing irreversible DNA degradation (against people, plants, animals).
There are a few things that have been shown to make it more effective at killing what you want to kill (germs), and not what you don't (people) usually by pulsing the light at different timings - but that's really pretty much about exposing people to as little as possible, while still achieving enough exposure to kill all different germ varieties within that time range.
With a son currently in an Intensive Care unit, who has been tested positive with VRE (google it), I can assure you that not all "super bugs" are just colds, flus or the like - some are bugs that can kill tiny children who don't have a chance to "get a bit dirty". The rate that these bugs can be transferred around a hospital is so scary (and I know, because I have to live with it, in hospital, every day with my son) that if there is actually an outbreak, I'd have serious, grave concerns for the health of some people. I'd prefer to have new technologies, like this UV tech, which can prevent the spread of these bugs, without having to give the patient yet another injection, or something else to digest, because sometimes the patients can't just keep being given the anti-biotics (something that actually leads to VRE). I'm still not convinced that UV emitters will ever replace chemical disinfectants, but I can see it as a great addition to the team, for those spots that often get overlooked when cleaning.

Deze lamp doodt de in het water aanwezige zweefalgen, waardoor het vijverwater helder wordt. Behandeling is goed mogelijk; een UVC-filter zorgt doorgaans voor een enorme verbetering in de helderheid van het water. De vijver wordt dan groen en troebel, als gevolg vanA zweefalgenA die in de vijver gaan groeien.


This output at 253.7nm is highly effective to inactive microorganisms such as algae, bacteria, virus, yeast and mold. These infections kill around 100,000 vulnerable patients and cost the American healthcare industry $US30 billion annually. UV light is present in natural sunlight and, although the most damaging wavelengths (extreme UV from 10nm to 120nm and midrange UV from 280nm to 315nm) are filtered by our ozone layer before they penetrate the atmosphere (97 per cent of UV overall), all wavelengths can alter molecular bonds and are capable of damaging biological tissue. Many American utilities have also been using UV methods for water sterilisation (both potable and wastewater) since 1916 and the practice has garnered EPA approval. Eighty-six per cent of the light emitted by Mercury-vapour lamps shines at 254nm, near one of the germicidal peaks, however these lamps are energy intensive and filled with a toxic gas.
Perhaps, just maybe, you don't realise the difference between the technologies and didn't think that this Gizmodo article may be more informed than you, or I. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable. Deze manier van filteren is dan ook bedoeld voor vijvers die te kampen hebben met groen water als gevolg van zweefalgen.
In deze UVC-unit stroomt het water langs een ultraviolette lamp, die de zweefalgen in het water doodt.

The fixture is high quality with a long lifespan and low mercury dosage to meet environmental demands. To combat hyper-infectious agents, like Clostridium difficile (C-diff) or Methicillin-resistant Staphylococcus aureus (MRSA), doctors are turning to a different method of disinfection to destroy bacteria by tearing their DNA apart with UV light.
The most common form of ionising damage incurred by humans is sunburn, though UV rays will burn through a cornea if given the chance.
Xenon pulse lamps, flash a UV light much more energetic than what Mercury-vapour can produce, which reduces disinfection time, and utilise an intert gas instead. When this material is irradiated with ultraviolet light, strong oxidizing agents called hydroxyl radicals and super-oxide ions are formed.
At least in the US, facilities are very aware how much the environment can impact risk for infections. As such, they require a clear line-of-sight unobstructed by shadows, dust or fluids preferrably in a sealed environment, which allows cycling air currents to repeatedly pass under the lights. Because the organic material is completely oxidized by this process, the photo-catalytic reactor is self-cleaning relative to organic material on the catalyst surface.The effectiveness of Photo-oxidation PO (Small trace of ozone)Several common odors such as second hand cigarette smoke, musty odors, ammonia and some allergens do exist in our working and living environment, public area as well as in toilet. All these odors or gases more or less have side effect on our health and sometime it is very difficult to get rid of these odors.
All you have to do is to use an AirSteril with photo-oxidation composite UV lamp tube built in and let the machine to generate a small trace of ozone into the air.
When microorganisms in the air encountered ultraviolet, UVC band will penetrate the microorganism cell membrane and nucleus. Nucleic Acid, Pyrimidine, Purine and Protein absorb wave and photons, the chemical effect will destroy microbes molecular, and thus the microorganism loses the ability to replicate and lively.
Result indicated shows that Protein absorbs UVC band at 280nm, Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) between 250-260nm band.
