    Benefits of Microlene’s 3 Stage UV System
    Microlene’s proven three-stage Filtration and Ultraviolet disinfection systems can provide continuous clean, safe and fresh tasting water from your rainwater tank. In conjunction with pre-filtration, UV is the best practical option for treating drinking water and is widely used in disinfecting the drinking supplies of not just individual homes, but entire towns. Automatic UV lamp and pump management systems ensure only disinfected water is delivered. Anti-cycling controllers eliminate energy wasting and nuisance pump cycling, maximising efficiency and  convenience.

    The Aquashield Centurion UV System consists of:

    • 20 micron pre-filtration for the removal of dirt
    • rust, sediment and debris reduction (step 1)
    • 1 micron depth filtration for parasitic cyst reduction and further sediment reduction to reduce ‘shadowing’ of pathogens (step 2)
    • Steriflo UV disinfection system with low pressure lamp and test tube quartz sleeve for easy cleaning and high performance (step 3)
    • Universal flow direction. Left to right or right to left via the unique bracket
    • The active system can be mounted in under 5 minutes
    • Lamp count down timer with set limit of 9,000 hours (approximately 1 year) matches lamp life and ensures only disinfected water is delivered*
    • Intelligent pump shut-off if the system alarms. Ensuring disinfected water is supplied at all times*
    • Override function available if emergency water is required
    • Note: Cannot treat water contaminated by metals, chemicals or algal toxins.
    • Subject to routine maintenance outlined in the installation and operation instructions.
