Davey is serious about water treatment!
Most of the serious water contamination outbreaks which have made headlines in New Zealand over the past several years such as Havelock North and Queenstown, are concerned with mains water supply. While we don’t want to get into the debate about how mains water is treated by councils, we know that there is only one way to guarantee the quality of your household water and that’s through three-stage UV water filtration.
How do you choose the best water treatment system for your home?
At Davey, we’re not talking filtering a bit of sediment or chemicals – we’re talking complete annihilation of organisms that can seriously hurt your family. Which is why the Microlene Aquashield Centurion is our best-selling water treatment system for whole house water treatment. This neat and tidy unit contains coarse filtration, fine filtration, and UV sterilisation and can be retrofitted to your existing plumbing.
What is three-stage UV filtration and how does it work?
There is only one way to ensure your water is entirely free from harmful bugs and bacteria such as cryptosporidium and giardia, and that’s by using UV sterilisation as part of a three-stage water treatment system.
The Davey Microlene Centurion Aquashield is a whole house water treatment solution which can be fitted to the existing plumbing of your mains water supply in a neat and tidy unit – giving you total peace of mind that your water is safe to drink, bathe in and brush your teeth with. Here’s how it works:
Stage 1: Coarse filtration – this is where larger particles of dirt, decaying leaves, rust and scale are captured. Poly Pleated Sediment filter cartridges are used here as these can hold a lot of dirt without affecting your water pressure, plus they can be cleaned and reused.
Stage 2: Fine filtration – this puts a stop to the smaller particles and further removes rust along with sand, silt, algae and cryptosporidium cysts (>99% effective for a 1 micron cartridge). We use Polyspun Sediment filter cartridges which have no chemical residue or loose fibres.
Stage 3: UV filtration – this is where the magic happens. Water passes through a cartridge containing a UV lamp which absolutely annihilates the organisms living in your water. Goodbye cryptosporidium along with viruses like SARS CoV and hepatitis, bacteria like E. coli and salmonella, algae and fungi, and cysts like giardia.
