Ultraviolet Systems

Ultraviolet water treatment systems can be used to purify and disinfect water for practically any application ranging from domestic drinking water to swimming pools and industrial processes. When correctly installed, the UV system is both cost effective and environmentally friendly, especially as it replaces chlorine in many swimming pool disinfection systems. When used in swimming pools, ultraviolet radiation photo oxidises and eliminates chlorine and other pollutants, and provides disinfection without the use of chemicals. This has become an increasingly popular method of purifying and disinfecting water in private swimming pools and hot tubs as well as those for public use. The process also protects the bather from any bacteria and acts instantly.

The UV system has a low capital, installation and maintenance costs compared with other chemical water treatment systems. This has the great advantage that there are none of the restrictions on water flow that are encountered with chemical methods. However, some caution is necessary when using UV for water treatment; Poor quality water can impair ultra violet lamps. If the lamp is coated with organic material or lime scale the disinfection process will be incomplete. Therefore it is essential to know that ultraviolet irradiation cannot be used in hard water; The UV bulbs also have to be replaced regularly as the manufacturer’s stipulations. The real problem is that there is no way a householder will know if the water is disinfected properly short of a full chemical analysis in a laboratory; Another issue is that UV performance can be impaired by any fluctuation in electrical supply. Ideally, a UV lamp should have a dedicated and secure power supply. The lamp should never be installed in a circuit where the load is extremely variable or in great demand. It is important that the lamp is properly equipped with warning lights that indicate when the bulb will need replacing.
