LIT DUV Drinking Water Disinfection Systems

LIT DUV closed vessel ultraviolet drinking water disinfection  systems, equipped with LPHO Amalgam lamps, are the product of choice for potable water applications. The DUV series offer an environmentally friendly and effective disinfection solution, with unprecedented microbe inactivation, up to flow rates of 1000 m3 per hour.

LIT DUV equipment is certified to ÖVGW (ÖNORM M5873-1), the globally accepted quality  standard for UV disinfection of potable water. The UV dose of 400 J/m3 is verified by extensive tests, determining the true bacterial reduction.

LIT DUV systems are designed and manufactured according to international standards, using the highest quality materials and components for a safe, economical treatment of liquids with high UV transmittance. The hydraulically optimally designed stainless steel reactor systems will guarantee excellent flow mixing for an efficient and reliable disinfection performance.

Light-weight and long-lasting electronic ballasts are installed to increase energy efficiency and lamp performance.

Ultraviolet lamps are the heart and soul of every UV system. All LIT UV DUV systems are equipped with modern industrially manufactured Low Pressure  High Output (LPHO) mercury “Amalgam” germicidal lamps. These lamps, which are developed and produced by LIT Technology, are characterized by an extremely high UV output and superior energy efficiency. A unique internal coating limits the depreciation of UV output to a maximum of 10% at end-of-life. An effective disinfection performance is therefore guaranteed during the entire operation period.

Fewer lamps are required in a more compact space, reducing installation and operation costs.

A PLC based control system continuously monitors the applied UV dose in the reactor. Each individual UV lamp is monitored for operating status and elapsed lamp hours. All operating data are available through the operator interface.

The UV system can easily be integrated with the main control system of the treatment plant through various available field bus interfaces.
