How to Specify UV Systems

The use of Ultra Violet (UV) light has now become standard practice in a vast range of industries including municipal drinking water and waste water treatment, Industrial process and manufacturing, offshore and marine and aquatics.  Ultraviolet disinfection systems are used to ensure water is free from harmful organisms, and is a proven, regulated and environmentally friendly technology.    

In order to provide the best Ultraviolet system to suit your needs, the following variables are required to size a UV system for a specific application.  The following information is helpful but not essential to providing a quotation: -

• Flow e.g. 150 m3/hr
• Application e.g. Drinking Water / Waste Water / Swimming Pools
• Water Source e.g. Borehole / Surface Water / Final Effluent
• UVT (Ultraviolet Transmittance) e.g. 90% UVT
• Details of pre treatment e.g. Filtration
• Intended use e.g. Irrigation / Drinking Water / Process Water
• Known biological challenge e.g. Cryptosporidium reduction
• Known dose standard e.g. 30 mj/cm2 minimum / 60 mj/cm2 average
• Treatment Cycle e.g. Single pass treatment or re-circulation
