nutrient solution disinfectionUV Treatment of Water Used in Hydroponics

UV water disinfection is ideal for nutrient solution disinfection in hydroponics and greenhouses. UV disinfection will kill waterborne pathogens in recirculating hydroponics systems. UV disinfection is cost effective, chemical free, simple to maintain and safe to use, killing all known pathogens. Unlike alternative forms of disinfection there are no external heaters, no chemicals, and no significant maintenance requirements. The use of UV for nutrient solution disinfection leads to the production of healthier plants with no toxic by-products, pH changes or temperature fluctuations.

Davey UV water disinfection systems are ideal of nutrient solution disinfection, with easy to install packages that include filtration, pumps and UV disinfection in an easy to install package.

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.

UV Treatment of Water in the Food and Beverage Industries

In an increasingly regulated and safety-conscious market, the food and beverage industries have to meet ever more stringent standards of quality. Microbial growth due to contaminated water or ingredients can cause discolouration, off flavours and shortened shelf-life. The threat of contamination is further increased as manufacturers respond to demands for less chemical additives and preservatives. Effective microbial disinfection of the whole process is therefore essential. UV treatment of water is ideal for the food & beverage industries.
