WATA Products

WATA is an electronic device used to produce active chlorine for disinfection out of salt, water, and electricity. The WATA products produce the sodium hypochlorite equivalent to 6 g/L (0.6%) at different rates (1 g/hr to 80 g/hr) depending on the model.  One liter of the solution is enough to treat 4,000 L of drinking water. Supplies required: clear water, salt (400 g/L of water), and electricity (30 W or 110-220 V). WATTA includes 5 devices with different active chlorine production capacities. The design specification for individual WATTA products can be found here.

WATA devices have been sold for almost 10 years to large organizations such as WHO, ICRC, UNICEF, Swiss Agency for Development and Cooperation, MSF, OXFAM, HELVETAS, CARITAS, and others.

Limestone deposits are formed during production which needs to be cleaned with 1:1 clean water and vinegar solution to ensure efficiency.

Ideally, the power supply is to be placed in a room adjacent to the production room. If this is not possible, place it as far as possible from the container where the chlorine is produced, in order to avoid contact with chlorine vapor which is highly corrosive.

The power supply should not be placed on the floor level and the devices need to always be immersed in the saltwater solution before being plugged into the power supply. The devices need to be rinsed with clear water after each production.
