LIFF Ultra Violet Water Disinfection Units

Liff / Water Treatment / Disinfection



Ultra violet disinfection units

Disinfect drinking water without using chemicals so that living contaminants such as e-coli, cysts and bacteria are completely eliminated.

The size of the unit is dependent on the amount of water being treated. Smaller units treat lower water flows and are best installed on the cold feed to a single tap e.g kitchen sink. Larger units treat higher flows and are suitable for installation on the incoming mains pipe offering whole house protection.

The Cartridges will need to be changed every 3-6 months and the UV lamps need to be changed every 9 to 12 months (dependent on whether the unit is left on constantly or periodically switched off). NB. Switching UV off will reduce lamp life.
