Range of WATA

The WATA technology, developed by Antenna, uses a simple, manageable process of electrolysis to convert a measure of salt and water into sodium hypochlorite. The resulting solution can be used for drinking water chlorination or as a disinfectant for use in households, hospitals or community clinics.

The WATA is specifically designed for use in the context of communities in developing countries. With this system, communities can source locally and quickly available chlorine to protect against diarrheal diseases such as diarrhea or dysentery. Eventually, this system can be a source of income through the sale of chlorine produced.

Even if it is intended for development projects, it can also be used in emergency situations due to its simple and rapid operation.

WATA benefits

Populations autonomy

Decentralized production is geared to the local demand, thus users are independent from any external chlorine supply and avoid transport and storage problems.

Simple use

Just running the device only requires clear water, kitchen salt and any source of electric current (local grid, generator, battery, solar panel…). A short, hands-on training is needed to operate the devices properly.

Reliable

When used correctly, WATA devices produce a regular concentration of active chlorine of 6 g/L. The quality control tools developed by Antenna make it possible to check the concentration reached and the water quality after dilution.

Sustainable 

WATA devices are designed to suit field conditions optimally in developing countries.

Low cost

The cost price for one litre of active chlorine concentrate is CHF 0.06 cent. This one litre of concentrated solution is enough to treat 4,000 litres of contaminated water.

Adaptable

Antenna’s range of products allows you to select the device which will fit best to the project needs. It will provide water to a health centre, a small community, a city or a region.
