UV Treatment of Water Used in Small Business & Farms

UV water disinfection systems help make your captured water safe. Bird and animal droppings can contaminate your rooflines with micro-organisms such as virus, bacteria and paracitic cysts. UV light generated at 254 nanometers is commonly used by councils and industry to treat a wide range of water sources and to inactivate micro-organisms found in water. This same chemical free water treatment is now available in economical packages suitable for small business, farms, guest houses and even large homes.   Passing filtered water through a UV water disinfection unit exposes the organisms living in your rainwater tank to a dose of UV light sufficient to inactivate the majority of common water-borne threats. UV treatment leaves NO residual chemicals in your drinking water and it's impossible to overdose.  Learn more about how UV works.

Steriflo UV Systems

Any business, farm, or larger householder looking for safe, secure, chemical free water should consider a Steriflo UV system. UV treatment is not just for drinking water, it is also ideal for treating water used in food production, fish breeding or anywhere where safe, chemical free water is needed.

The Davey Steriflo UV system works by exposing micro-organisms to UV light. The Ultraviolet disinfection lamp sterilises viruses and bacteria. The water treated with the Steriflo UV disinfection system is chemical free, safe to drink, has no odour and no flavour. It is is also safe to use and impossible to overdose.

Source water containing sediments can "shield" micro-organisms from the UV light of an ultraviolet disinfection system, so the Steriflo is best used on clean, clear water to ensure all micro-organisms get full UV exposure for complete inactivation. So, it is best to compliment your Steriflo UV system with Davey filters removing any sediment before the water is treated with UV light. The Steriflo UV system is best place in your line after any other treatment and just before use.

Who Should Use Steriflo UV System?

Steriflo is ideal for:

  • Fish breeders looking for a chemical free water source
  • Guest houses looking to boost pressure and disinfect drinking water.
  • Farms looking for a way to treat dam and rain water tank water before use, either in production or for drinking.
  • Small food related businesses looking for chemical free, safe wash down water.
  • Large households needing pressure boosting and disinfection of tank water
  • School showers and toilet blocks
  • Commercial toilet flushing
  • Small industry process water
  • Bacteria and algae growth control for aquaculture and water features
  • Also suitable for clean bore and surface water treatment (subject to a water test)

Looking After Your Steriflo

It's important to keep the Steriflo light source clean. Mineral deposits on the lamp sleeve are common and should be cleaned off every 3 months or more frequently if the water is hard. The sleeve is easily cleaned with CLR solution. The UV lamp should be replaced every 12 months to ensure an adequate dose of UV light for inactivating micro-organisms.

The Benefits of the Steriflo UV Disinfection System

Bird and animal droppings can contaminate your rooflines with micro-organisms such as viruses, bacteria and paracitic cysts. UV light generated at 254 nanomaters inactivates micro-organisms by damaging their DNA and without the ability to reproduce they can't cause infection in humans.  Passing filtered water through a Steriflo unit exposes the organisms living in rainwater tanks to a dose of UV light sufficient to inactivate the majority of common water-borne threats. The Steriflo UV treatment leaves NO residual chemicals in your drinking water and it's not possible to overdose.
