3. PROCEDURE FOR PRODUCING SODIUM HYPOCHLORITE SOLUTION

3.1 PREPARATION OF THE SATURATED SOLUTION

1 Take a container of any size (never use metal) and fill it with water.2 Add large amounts of salt (about 400 g of salt per litre of water). Refined salt is preferable. 3 Shake/mix regularly for 15 minutes so that a maximum amount of salt has dissolved. Let

the solution rest.4 Make sure there is salt in the bottom of the container. Close and label it. If there is no

salt left in the bottom of the container, add more and repeat the procedure beginning with Step Number 3.

A solution prepared in this manner may be kept for a long period of time. Do not agitate the container containing the saturated solution and do not forget to check that there is salt in the bottom before each use.

2. NECESSARY MATERIALS ` 1 container holding approximately 2 L (supplied) ` 1 AC/DC power supply to connect to the network:

- Input voltage: 100 - 240 VAC - Input frequency: 47 - 63 Hz - Input current: 0.4 A/230 VAC - Output voltage: 12 VDC - Nominal output current : 5A

` 1 WATA-Standard kit ` 1 control box ` Ordinary salt ` Clear water (between 20° and 27°) ` Funnel ` Small wooden/plastic table ` 1 syringe of 50 ml ` 1 container for the saturated solution

The WATA-Standard produces 2 litres of sodium hypochlorite solution in 2 ½ hours, which can treat about 8,000 litres of water, meeting the drinking water needs of 2,000 people (4 L/person/day). The WATA-Standard works with direct current and consumes a nominal power of 48 W.

1 Once the saltwater solution is ready, immerse the WATA-Standard until the device is fully submerged in the solution.

2 Connect the WATA-Standard to the control box.3 Connect the power supply to the socket, then connect the control box to the electric power sup-

ply. The timer will start; the LED light will turn green and the electrolysis process will begin. 4 After 2 and 1/2 hours the process will automatically stop, after generating 2 litres of

sodium hypochlorite solution (6 g/L). The LED light on the control box will flash orange. 5 At the end of the process, disconnect the WATA-Standard, remove it from the sodium

hypochlorite solution, and rinse it in clean water.6 Disconnect the power source, then the control box and put them away. The push button on the box can be used to reset the timer, if necessary.

4. WATA-STANDARD MAINTENANCEAfter each use, rinse the appliance by immersing it in a bucket of clear water. Dry and store in a secure, dry place, protected by a clean cloth. Never rub the titanium plates.

3.2 PREPARATION OF THE SOLUTION FOR USE WITH THE ELECTROLYSER

With the large syringe (50 mL, supplied in the kit), add190 mL of the saturated solution per 2 L of water to be electrolyzed then continue to fill your container with clear water (total volume 2 L).
