The Naiade water disinfection unit is a spin-off from Nedap’s and Trojan’s know-how of large scale drinking water and industrial waste water treatment plants. The Naiade drinking water disinfection unit very effectively combines the potential offered by solar energy, UV light and battery back-up.
# a UV light, which kills any remaining bacteria and viruses
===Suitable conditions ===The unit has been designed for operation under harsh conditions in grass root societies. Units can be installed, operated and maintained by people with no or little/low technical education or background. {{procontable | proborder="1" cellpadding="5" cellspacing="0" align="none"|-! width="50%" style="background:#efefef;" | Advantages! style="background:#f0f8ff;" | Disadvantages|-| valign="top" | - Immediate use after installation <br>

The Naiade can be installed in 30 minutes by local people without a
technical background. A step-by step, pictured instruction leaflet and tools are provided.
The capacity is about 3,500 liters per day, depending on the scale of organization.
The disinfected water fulfills the World Health Organization standards. Pathogen reduction rates up to 99,9999 99% are obtained in many applications. (More details are available on request). It is strongly recommended to use separate containers for the raw and disinfected water to avoid recontamination.
The unit can function at night using a car battery of not less than
A supervision structure to guarantee optimal use is highly recommended.

The unit does not contain any moving parts except for the electro-magnetic tap.
It is made of tropical resistant poly ethylene. All material as well as the applied technology is based on the intensive use in remote and tropical areas. The device was laboratory test from Unesco-IHE, Institute for Water Education. Field tests were done by the Water Research Institute of the Council for Scientific and Industrial Research, Ghana and ATIRA-Ahmedabad, India.Amongst others, received two prestigious international awards on sustainable development.
====Estimated Lifespan====
The estimated lifespan of the unit is over 10 years. Filter bags and UV lamps may need earlier replacement.
