Davey Water Treatment & Filtration

Why treat your water?

Families are more focussed than ever on making sure their water supply is safe to drink. The Microlene range of water treatment solutions has been developed over a period of over 20 years. With the backing of Davey Water Products, itself a company with over 88 years of experience in water technology.

1. Unwelcome Organisms

Ultra Violet Treatment for Rainwater

Microscopic living organisms such as bacteria, mold, viruses and parasitic cysts (e.g. Giardia and Cryptosporidium) can thrive in untreated water supplies. Exposure to Ultra Violet light with the Microlene Aquashield system is a safe and very effective way to neutralise these unhealthy organisms from your harvested drinking water.

2. Tainted Water


Families seek different solutions; from simple taste and clarity issues through to a range of wider concerns. Water can be discoloured and tainted by dust, rust, sediment, algae, decaying organic matter and chemicals. It can also contain aluminum, lead, asbestos, chlorine and sediment. Microlene’s superior range of water treatment solutions can swiftly clear these impurities by passing them through the correct filtering option.

Microlene water treatment options

Microlene 3 Stage UV Disinfection System

Microlene’s proven three-stage Filtration and Ultra Violet disinfection systems can provide continuous clean, safe and fresh tasting water from your rainwater tank.
In conjunction with pre-filtration, UV treatment options are the best practical solution for treating drinking water and are widely used in disinfecting the drinking supplies of not just individual homes, but entire towns. Automatic UV lamp and pump interlock ensures only disinfected water is delivered.

Ultra Violet Water Treatment System for Rainwater Tanks

Suitable for Urban or Rural Properties

An economical means of managing bacteria and viruses in drinking water supplies, best used with pre-filtration to ensure the highest penetration of UV light. Provides 30mJ/cm2 at 90% or above UV Transmission (UVT).


Passing filtered water through a Steriflo unit exposes the organisms living in your rainwater to a dose of UV light which is sufficient to inactivate the vast majority of common water-borne threats.


Bird and animal droppings can contaminate your rooflines with micro-organisms such as viruses, bacteria and parasitic cysts leaving your water unsafe for drinking and has the potential to cause illness.


Microlene Steriflo systems generate Ultra Violet (UV) light at 254 nanometers, inactivating micro-organisms by damaging their DNA. Without the ability to reproduce they cannot cause infection in humans.


UV treatment does not leave any residual chemicals in your drinking water and it is not possible to overdose.

Microlene Filter Housings

The size of housing is determined by how many taps or appliances you want to provide water to. For a single tap, a standard 10” will suffice and for anything larger, a Jumbo 10” or 20”. The most successful installation will have two filters set up in series so that a pre-filter of 20 micron captures the majority of the coarse dirt, shielding the second stage of filtration. This would typically be two Jumbo 10” or 20” cartridge filters installed on the main cold water line entering your house followed with a UV disinfection system. Cooking and drinking taps are then protected with a Standard 10” purification filter.
Microlene’s filter housings are constructed from reinforced polypropylene for durability, are supplied with mounting brackets and hardware for easy installation and pressure relief valves on most models (for ease of cartridge removal).

Microlene Twin Housings

Twin Filter Housings Kits – Rainwater or Mains Water Ready to install, standalone Twin Housing on Rack supplied with the choice of 10” Standard, 10” Jumbo, 20” Jumbo housings. Different sizes for different flow rates. Paired with matching cartridges to either suit Rainwater (treating sediment and parasitic cysts) or Mains Water (treating fine sediment, taste and odour).
