UV filtration

What it is and how it works

Ultraviolet is a term used to describe the wavelength between the blue violet range of the visible spectrum and the shorter wavelength or X-rays.

The ultraviolet spectrum is divided into three separate bands: (1) UVa from 315nm to 400nm (2) UVb from 280nm to 315nm (3) UVc from 200nm to 280nm

UVc is often referred to as the germicidal wavelength, because of its ability to destroy micro-organisms. The lamps in all our UV sterilisers emit a wide range of ultraviolet with its most significant part at a wavelength of 253.7nm, which has been found to be the most efficient for germicidal action.

When water is passed through a UV steriliser, micro-organisms contained in the water encounter UVc radiation emitted from the germicidal lamp. The UVc radiation penetrates the cell membrane and thereby either destroys or debilitates the microorganism.

Different micro-organisms vary in their susceptibility to UVc radiation.

The most sensitive and hence, the easiest treated, are some bacteria and most phototrophic organisms such as those often found in ponds and aquaria. Bacteria, such as Escherichia coli which can contaminate drinking water supplies, are easily controlled by relatively low levels of UVc and therefore low level UVc radiation has been employed by the drinking water industry for many years.

The most resistant micro-organisms to UVc are protozoans which may, when compared to simple bacteria, require several hundred times the radiation dose to destroy them.

Generally, the larger the organism, the larger the UV dose required to damage it. There are many hazardous and pathogenic aquatic organisms that can be controlled given the correct UVc radiation dose.

Correct application will dramatically reduce the likely spread of most primary infections such as Oodinium sp. and Cryptocaryon sp., at the same time almost eliminating the risk of secondary bacterial infection which is so often the real cause of fish loss. This is achieved by controlling potential populations of heterotrophic bacteria which are often associated with an unhealthy aquatic environment.

Factors Affecting Germicidal Action

Lamp Temperature

It is important that the UV lamp reaches its optimum operating temperature of 40°C otherwise the lamp will not generate the maximum amount of UVc radiation possible, and the efficiency of the unit will be compromised.

For this reason, all UV water sterilisers must be fitted with a protective fused quartz glass sleeve, which keeps the UV lamp from direct water contact, which would otherwise act as a coolant. Units should also feature sealed end caps which help to maintain the lamp and the air around it at its constant optimum running temperature.

The protective sleeve employed must be manufactured from fused quartz glass, which allows the highest possible amount of UV light to penetrate the water.

Other materials should not be used as they can have a significant impact on the effectiveness of the steriliser by significantly reducing the amount of UVc that reaches the water.

Water Clarity

Dirty or turbid water with suspended particles will absorb the UVc radiation and dramatically reduce the effectiveness of the unit. It is important to ensure that the UV steriliser is placed at the end of the filter circuit, before the water returns to the holding tanks to ensure that the water passing through the steriliser is as clear as possible.

Dissolved organic compounds also reduce the distance of penetration of the UVc radiation. Typically, in any aquatic environment with fish or other animals present, there is a gradual build up of phenolic compounds and other organic dyes. This build up of organic dyes is often referred to as ‘yellow water syndrome’ and can be dramatically reduced by filtering through a good quality activated carbon (e.g. HR Carbon) or by using ozone gas.

The truth about UV Sterilisers

Safe for all types of aquaria and desirable tank inhabitants; UV technology reduces pathogen levels in the water, lowering the risk of infection to both animals and fish keepers!

• Kills most harmful bacteria and viruses and eliminates water-borne algae;

• Only targets the micro-organisms floating in the water, so the good bacteria needed for processing ammonia remain healthy in your filter system, rock and substrate;

• Improves water quality by breaking down organics;

• Decreases the levels of fungi such as yeast and moulds;

• Reduction of odours in the water;

• Creates a cleaner environment to safely introduce new tank inhabitants;

• Significantly reduces the spread of disease in the aquarium;

The next generation of UV sterilisers

This photocatalytically enhanced form of sterilisation is 33% more effective than a standard UV steriliser;

Increased capacity means that these units are more energy efficient – the same amount of power treats more water.

Specially selected photocatalytic material protects and further improves the lifespan of the high UV resistant plastic body.

Production of highly reactive hydroxyl radicals works like ozone to oxidise organic and in-organic matter and further improve water clarity (see more on page XX).

COMPLETELY SAFE: the reaction is all contained within the unit, producing only clean water and carbon dioxide.

Bursting the myth about AQUARIUM STERILISERS

Vecton UV sterilisers are suitable for single livestock tanks and for other smaller applications including agriculture, horticulture and hydroponics.

Q.

“But a UV steriliser will kill the good bacteria that my aquarium needs ?”

A.Vecton & Vecton Titan UV targets ONLY the microorganisms floating in the water, so the good bacteria needed for processing ammonia remain healthy in your filter system, rock and substrate.

Q.

“How does the Vecton titanUV compare with the standard Vecton?”

A.Both are UV aquariums sterilisers. The photocatalytic reaction created by the Vecton titan uv technology makes it 33% more effective than the standard Vecton and provides a safer alternative to ozone for even cleaner water.

UV Pond Clarifiers

Tropical Marine Centre pioneered the development of UV water cleansing systems and has manufactured them successfully since the late 1970s. There are now four pond ranges available:

Pro Clear Ultima UV30 & UV55

Pro Pond UV15, UV25, UV55 & UV110

Pro Pond Advantage UV110

Pro Pond Titan UV UV110

How Do They Work?

Ultraviolet radiation at a wavelength of 254 nanometers is extremely effective in halting the reproduction of algae. The algae readily absorbs the UV light which damages its DNA structure and makes it flocculate (clump together) allowing it to be trapped in a mechanical filter.

TMC’s range of UV pond clarifiers work on this principle. At the heart of each UV unit is an ultraviolet lamp sealed inside a quartz sleeve. As water is pumped through the unit, ultraviolet light from the lamp destroys the green, single-celled water borne algae (which make garden ponds murky and unattractive), leaving the water crystal clear.

UV Lamps & Quartz Sleeves

The importance of quality UV lamps and quartz sleeves in a saltwater aquarium UV sterilization system cannot be overstated.

Quality UV lamps are designed to emit the appropriate spectrum of UV light, particularly UV-C, which is most effective at sterilization. High-quality lamps produce consistent UV output over their lifespan, ensuring reliable sterilization of waterborne pathogens such as bacteria, viruses, and algae. This is essential for maintaining a healthy environment in a saltwater aquarium, where diseases can quickly spread among marine organisms.

Quality sleeves are designed to resist fouling, mineral deposits, and chemical corrosion, which can degrade UV transmission and damage the lamp. By keeping the lamp clean and isolated, a high-quality quartz sleeve helps maintain consistent UV output and prolongs the lifespan of the UV sterilization system.
