Galway Water Solutions sell an extensive range of ultraviolet sterilisers for both domestic and commercial use.

Standard 5 gallon per minute ultraviolet disinfection systems start from a discounted 300 euros as part of a larger well water combination system, or at multiple discount rates when sold in volume quantities.  Hyundai systems range from 700 euros for 5 gpm systems to 1200 euros for the 10 gpm (12 US gpm).

The very top end ultraviolet systems we offer include the full Viqua Trojan range of NSF certified ultra violet germicidal lamp systems.  No other ultraviolet lamp matches Trojan for a wide range of options, 316 stainless steel enclosures, internally polished reactor chambers, pure quartz sleeves, 2 year life lamp options, solenoid valve feed supply cut off options, system performance control modules, quick change lamp and quartz sleeve design.

All ultraviolet sterilisers include a 5 micron prefilter housing and cartridge as required by HSE guidelines.  Systems also come with up to 10 year warranty and service call outs are available for annual lamp changes.

ultraviolet information

Using ultraviolet to sterilise bacteria, began in the 1960’s and later on Atlantic, Trojan and Wedeco developed commercial systems.  Due to it’s success, affordable ultraviolet systems became available, recommended by health authorities for safe bacterial sterilisation of contaminated supplies. Ultraviolet has now become the safest and most effective form of bacterial disinfection available, with working efficiences of up to 99.999999%.  Allowing a calculated flow of infected water to be passed in contact with a high intensity ultra violet (UV) light source deactivates the reproductive DNA of viruses, bacteria and cysts, rendering them harmless and causing subsequent cell death.

Modern ultraviolet disinfection uses hour counting meters to monitor ultraviolet (UV) lamp life and ensure optimum sterilisation power along with audible and visual warning sensors incase of ultra violet lamp failure. For peace of mind, ultraviolet systems can be upgraded to double the kill rate along with commercial systems offering solenoid valves in case of electrical power cuts, feed back and telemetry to remote monitoring and automatic wipers to regularly clean the quartz crystal sleeves inside the units in case of variable source water chemistry.

Ultraviolet disinfection systems for household use typically operate on a power usage of around 20 to 40 watts and require a new bulb every 12 months costing from 50 euros along with 5 micron prefilter cartridges. Ultraviolet steriliser systems work best on water free of water hardness, colour, turbidity and insolubles that obstruct the transmission of ultraviolet rays. Unless water is naturally soft, sourced from a granite rock area, a water softener will soften any level of scaling.

Health authorities rate safe levels of contamination as less than 1 organism in 10 litres of mains water with ultraviolet bacteriocidal units being effective above the 99.95 % sterilisation range. When levels of contamination are recorded in a water supply by measuring an average level of pathogens per litre of water, it becomes easy to calculate a safe threshold for drinking use. If a mains water scheme has established a good track record of disinfection using modern treatment, the level of post treatment at domestic level should be able to be kept to a minimum.
