CLOVERLEAF SMARTSTART UV LAMPS WITH INTEGRATED BALLAST



The Benefits Of UV Clarifiers:


Single cell algae forming green water are not just unpleasant to look at, but at the same time contribute to lowering the “kh” value which is so important to fish health, and to the nitrification process within the filter system. Algae also contribute towards lowering oxygen levels, whilst meanwhile increasing “ph” levels – both of which are not desirable. The use of Ultra Violet is the safest of international techniques for obtaining clear water, and unlike many chemicals detrimental effects or pollution is impossible. In addition general plant and pond life are unaffected with a UV.

The actions of ultraviolet light onto single cell algae does not actually kill them, but converts the algae DNA structure to the point where they flocculate together, and thus form larger particles which will not so easily pass through the mechanical filter mediums. The amount of sunlight which the pond receives is the biggest of factors in the promotion of algae, and for such reasons the selected size of a UV unit should take such environmental aspects into account (see UV Calculation Page

Attributes Of Germicidal UV Lamps:

All Cloverleaf UV Clarifiers make use of quality Germicidal lamps with a specification wavelength of 254nm (nanometres) - also known as UV-C or shortwave. This range is proven (and accepted in all circles) to be the most effective in germicidal applications, and is used in many industrial application for disinfecting contaminants that pollute both air and water. Such achievement are made in that when living micro-organisms or organic material is subjected to shortwave ultraviolet light in the spectrum range of 240nm to 280nm the DNA structure of the substance is broken down and thus technically destroyed.

Whilst it is scientifically correct that UV-C at 254nm is capable of destroying biological contaminants such as mould, fungus, bacteria and viruses, this is sadly directly related to exposure time - with that exacting time being paramount to the process. Alas if by example we were to evaluate a hypothetical setup of say a 3,000 gallon pond served by a single 55 watt UV unit with a through flow rate of 1,500 gallons per hour the end result is that not enough contact time/exposure has been provided in order to destroy 100% of detrimental bacteria/organisms. It may well be the case that 10% are destroyed, but that is no great asset especially when that amount might have died or disappeared on their accord a few hours later.

The life form of single cell pond algae (which form green water) are such that they only need to be in contact with ultraviolet UV-C for a very short exposure time in order to be destroyed, and this is why the majority of UV Clarifiers on the market are successful in varying degrees.

It’s a worthy example to make mention of a past Cloverleaf commercial installation involving a 1,000 gallons of water with a small fish load where the goal was to provide 100% disinfection by Ultraviolet. In relying upon 20 years of experience Cloverleaf opted for a design which was based on a flow rate of around 600 GPH through a 440 watt 8 bar UV unit. The end result achieved the objective, but ONLY because the exposure time when passing through 8 continuous 55 watt radiation chambers was sufficient to do the job. To put this into proper perspective we are talking about a radiation chamber around 16 feet long (4.8 metres).

The background to the alleged “killing power” of UV’s goes back to the around the 1980 period when all aquatic UV’s were described/marketed as a “UV Steriliser”. Such a description was really technically inaccurate (for the reasons as set out), and in the years which followed European countries changed the product description to “UV Clarifier” - although still today the USA frequently use the hyped up term of “UV Steriliser”. Perhaps some sources today simply use the reference “UV” in the hopes that any prospective purchaser will assume the classification as a “UV Steriliser” ?

From the above account it should hopefully be appreciated that Cloverleaf act professionally and honestly i'm not making any claim that their UV’s have a marvellous killing power to all forms of bacteria or viruses. Yes, the claim could be technically possible in stretching the imagination, and the example 440 watt UV installation noted above illustrates this fact, however this is not the circumstances or background facts under which the average pond keeper selects the purchase of a UV unit.

The potential purchaser of a Cloverleaf Ultra Violet Clarifier can however be fully assured that the product incorporates the use and technology of the best components available, with the Smartstart Germicidal 254nm Lamps (with built in ballast/starter units) being the very best and most consistent performer that is on offer within the international market. The units which are designed to provide clear water do exactly just that, and any other minor attribute is just a small bonus.
