UV Disinfection & Sterilisation Systems

The method of ultraviolet germicidal light being used in purification and disinfection of water is a unique and rapid method, without the requirement of heat or potentially hazardous chemicals.

UV Units will generally destroy the vast majority of bacteria, algae, potential viruses and other micro-organisms in water and may be linked to other water treatment systems, such as Reverse Osmosis, in order to remove other pollutants such as dissolved salts, heavy metals, chemical infusions and chlorine.

UV disinfection units, often called ‘UV sterilisers’ or ‘UV filters’, comprise a stainless-steel reactor chamber housing a UV lamp or lamps located inside protective quartz sleeves. This provides an enclosed environment in which water is circulated to ensure a high level of exposure without hazard to the area outside of the chamber.

UV water treatment lamps are tailored to emit shortwave radiation (at 254 nm), this being lethal to DNA contained within the cells of bacteria, virus and other micro-organisms. The UV radiation emitted causes breaks and modification of the DNA chain, preventing the bacteria from performing vital cellular functions and reproducing, effectively killing it. (The removal of organic and inorganic chemicals, including Chlorine, Chloramines, Ozone and Total Organic Carbon (TOC) emerging contaminants, is also commonly seen).

Throughout the years, ultraviolet technology has become well established as one of the water purification methods of choice. Not only is it one of the safest ways to disinfect water (UV rays being a natural component of sunlight) but as no chemicals are added in the process, there can be no danger of overdosing. Being a process that is free of by-products, UV water treatment is one of the safest, most effective, speedy and economical water purification methods available.
