WATA KIT: drinking water for 6,000 people

- Capacity: 1 litre of active chlorine concentrate per hour.

The standard WATA can treat up to 24,000 litres of water per day, covering the daily needs for clean drinking water of 6,000 people*.

- WATA device size: 18 x 5.5 x 4.5 cm

- WATA device weight: 0.200 kg

- WATA full kit size: 26 x 11 x 11 cm

- WATA full kit weight: 1.100 kg

- Power supply provided:  transformer 12V / 5A and pair of crocodile clips for an use with solar power supply of min 50W (solar panel not provided).

Solar power: WATA can be coupled with a photovoltaic panel of minimum 50 watts. Under this configuration, it must be connected to a charge regulator, itself connected to a car battery. In that case, it is important to recharge it after every 9 hours of functioning (for a 75 Ah battery) and not to let it unload beyond 50% of its total capacity (voltage under 11.5 V). You must get a voltmeter in order to check that the charged battery delivers minimum 13 volts. Make sure that the battery is connected to the WATA when measuring its voltage with the voltmeter.

The intensity (amperes) of the electric current provided for the electrolysis with WATA has to be as constant as possible, in order to guarantee a concentration of 6 g/L of active chlorine in the solution produced. Photovoltaic cells can hardly deliver such a constant current intensity. It is therefore necessary to make use of a battery simultaneously to using a solar power (as shown in the user guide). This way, the current intensity’s variations are buffered and passing clouds, for example, thus do not reduce the device’s production rate.

Content of standard WATA kit:

- 1 x standard WATA device

- 1 x power supply 12V/5A, (Meanwell LPF-60-12)

- 1 x paire of crocodile clips

- 1 x container of 2.5 litre

- 1 x WataTest reagent and  1 x WataBlue reagent

- 2 x syringes (50ml et 5ml)

- 1 x recommendations for optimal use of the WATA

- 1 x WATA user guide

- 1 x user guide of active chlorine

Maxi-WATA KIT: drinking water for 125,000 people

- Capacity: 12,5 litres of active chlorine concentrate per hour.

The Maxi-WATA can treat up to 500,000 litres of water per day, covering the daily needs of 125,000 people* for clean drinking water.

- Maxi-WATA size: 45 x 15 x 10 cm

- Maxi-WATA weight: 3 kg

- Power supply size: 38 x 19 x 13 cm

- Power supply weight: 4 kg

- Maxi-WATA full kit weight: 7.500 kg

- Power consumption: 720W or 24VDC X 30A

- Power supply provided: Transformer rated at 960W, delivering an output voltage of 24VDC. All you need to do is connect the transformer to the electricity network (120V-230V) or to a generator. For safety reasons, both options have to be earthed.

Using Maxi-WATA requires more attention than the two smaller models (see user guide). Only especially-trained people should use it. In particular, the strong hydrogen emissions produced during the electrolysis mean that no flame or spark should, in no case, be brought close to a functioning device. Moreover, you should not inhale the chlorine emanations produced during electrolysis, and you should work in a well-ventilated room. Finally, safety precautions must be taken (restricted access to the devices) in order to avoid any risk of electrocution.

Content of the Maxi-WATA kit:

- 1 x Maxi-WATA device

- 1 x power supply 24V/40A (Meanwell 960W) in a ventilated box

- 5 x WataTest reagent and 5 x WataBlue reagent

- 2 x syringes (50ml and 5ml)

- 1 x rrecommendations for optimal use of the Maxi-WATA

- 1 x Maxi-WATA user guide
