The use of sodium hypochlorite generators in water plants

Sodium hypochlorite generator is suitable for medium and large municipal water supply and drainage company,

industrial circulating water, oilfield reinjection and other fields

1. The softened water passes through the salt dissolving tank to produce the saturated brine solution.

2. Saturated brine is then dilute with additional softened water to provide a brine solution with a concentration of about 30 grams per liter of NaCl. Which then feeds the electrolyzer.

3. By applying direct current, the brine solution passes through the electrolyzer fitted with electrodes. Producing a solution of sodium hypochlorite with a concentration of free available chlorine of 0.8% (8000 ppm of active chlorine).

4. The PLC monitors the process parameters online, such as temperature and the level of electrolyte flowing into the electrolyzer, to ensure safe and efficient operation at all times.

5. Hydrogen gas will be remove from each electrolyzer separately and dilute by air before being discharg to the atmosphere, ensuring that the hydrogen concentration is far from the lower explosion limit. electrolyzers are design to remove hydrogen quickly and efficiently, thus improving safety.

6. After passing through one or more electrolyzers, the sodium hypochlorite solution flows into the storage tank. The electrolyzer measures the temperature in real time , to ensure that the system does not overheat during operation.

7. A liquid level sensor is place at the outlet of the last electrolyzer, ensuring that the electrolyzer is fully fill with electrolyte before the electrodes are energize.

8. The system is automatically controll by a PLC control cabinet with touch screen.
