Questions

Is the Naiade easy to use?

The use of the Naiade is very simple. Since an electronic part does all the 'thinking', such as, checking the status of the battery, the life time of the UV lamp and the charge level of the battery. One only has to press the button to start the purification of the water. The Naiade has been developed for use in rural communities with limited technical knowledge.

Does Naiade need a lot of service?

Maintenance is restricted to three items:

1. The container needs to be cleaned every now and then, to avoid scaling by algae.

2. The PV panel needs to be cleaned with a dry cloth, since dust/dirt would reduce the output of electricity.

3. The filter bags need to be washed every now and then in order to remove colloidal parts. After cleaning, they are re-installed. The replacement of the UV lamp, after 10,000hrs of use, has to be done by trained technicians.

Does it need to be installed by professionals?

How is the Naiade powered?
