Medium pressure UV systems
PREVENTING reactivation of bacteria -> permanent disinfection of treated water DISINFECTION of water and removal of combined chlorine simultaneously DUE TO unique LifeAGE® technology lamp lifetime can reach up to 18 000 operating hours.
advantages and disadvantages of Medium Pressure UV Technology
No bacteria reactivation (the disinfection is always permanent)
Removes bound chlorine
Ecological disinfection without chemicals
Higher energy consumption than UVL (but easily outweighed by benefits)
It is well known that bacteria and other microorganisms are capable of repairing their DNA damaged by ultraviolet (UV) radiation. Known as ‘reactivation’, it is a natural defense mechanism that has evolved over millions of years.
This self-repair ability posesses obvious problems when UV disinfection technology is used to treat potable water, swimming pool water, effluent or other liquids. A study proved that polychromatic medium pressure UV radiation causes permanent damage to bacteria and microorganisms, where monochromatic low pressure UV does not.
For any industry where UV is used to disinfect water or effluent, the operator needs to be sure that the treatment is permanent – that is the reason why to use medium pressure UV systems! The last version of DIN 19643 Norm clearly states: Only UV-M (medium pressure UV) systems can properly disinfect swimming pool water and lower the level of combined chlorine. Low-pressure UV systems are therefore not appropriate to be used for these purposes.
LIFETECH developed unique LifeAGE® technology exploiting advanced electronic power (AEP). Which in synergy with our profound knowledge of UV technology allows you to enjoy the lowest operating costs available today.
WIPER OF QUARTZ SLEEVES
It is necessary to periodically clean the surface of quartz sleeves. There are 3 options:
- Clean them manually (no wiper so you need to put the quartz sleeve out and clean it with a piece of cloth and your hand)
- Manual wiper (recommended for: private pools and jacuzzies)
- Automatic wiper (recommended for: public pools and jacuzzies, drinking and waste water plants)
Medium pressure UVM
Medium pressure UVM is the only UV technology to eliminate bound chlorine in pools – proven by German norm (DIN 19643).
UVM reduces Bound Chlorine
Best UV water disinfection (significantly better than by UVL)

Removal of triazine herbicides – drinking water resources
In 2005, laboratory and pilot studies on drinking water resources contaminated by triazine pesticides have been done by LIFETECH for Veolia Water.
Both low pressure and medium pressure UV systems exploit the power of UV radiation. However, there is a huge difference in...
