Range of WATA devices

We offer three different models of WATA devices: Mini-WATA, WATA-Standard and Maxi-WATA

Mini-WATA KIT

Capacity: The Mini-WATA produces 500 ml of active chlorine per production cycle. Each production cycle takes 3.5 hours and can treat up to 2 000 liters of water, covering the daily needs of 500 people for clean drinking water*. The active chlorine solution can be used for safe water and for desinfection as well.

Mini-WATA size: 17 cm

Weight of the kit: 350 g

Power supply provided: 5V / 1A (for electricity network 110V or 220V)

Solar power supply (optional): 5V converter and crocodile clips provided, which enables its direct coupling with a photovoltaic panel (panel from 6V to 18V, min 10-watt not provided).

Content of a Mini-WATA kit:

– 1 x Mini-WATA device

– 1 x power supply 5V/1A

– 1 x WataTest reagent and 1 x WataBlue reagent

– 2 x syringes (50ml et 5ml)

– 1 x Mini-WATA operating instructions

Price of a Mini-WATA Kit: 150 CHF **/ with solar option: 200 CHF **

WATA-Standard KIT

Capacity: The WATA-Standard produces 2 liters of active chlorine per production cycle. Each production cycle takes 2 hours and can treat up to 8 000 liters of water, covering the daily needs of 2 000 people for clean drinking water*. The active chlorine solution can be used for safe water and for desinfection as well.

– WATA-Standard device size and weight: 18 x 5.5 x 4.5 cm / 0.200 kg

WATA-Standard full kit size and weight: 26 x 11 x 11 cm /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-Standard 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-Standard 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-Standard kit:

– 1 x standard WATA-Standard 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 WATA-Standard operating instructions

Maxi-WATA KIT

Capacity: The Maxi-WATA produces 60 liters of active chlorine per production cycle. Each production cycle takes 4.5 hours and can treat up to 240 000 liters of water, covering the daily needs of 60 000 people for clean drinking water*. The active chlorine solution can be used for safe water and for desinfection as well.

– Maxi-WATA size and weight: 45 x 15 x 10 cm / 3 kg

– Power supply size and weight: 38 x 19 x 13 cm / 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 reagents and 5 x WataBlue reagents

– 2 x syringes (50ml and 5ml)

– 1 x Maxi-WATA operating instructions
