| No. | Content | Chlorine dioxide generator | Sodium hypochlorite generator |
| 1 | Making process | Sodium chlorate and hydrochloric acid reaction to produce chlorine dioxide
5NaClO2 + 4HCl(Concentrated)=4ClO2 ↑ + 5NaCl + 2H2O (Sodium chlorite method) | Electrolysis of brine to produce sodium hypochlorite solution NaCL+H2O=NaCLO+H2↑ |
| 2 | Raw material | Hydrochloric acid and sodium pochlorite | Not iodized salt |
| 3 | Raw materials form | Hydrochloric acid must be submitted for approval by the public security department | Salt Company record can be purchased and delivered to your door |
| 4 | Raw material inventory | Hydrochloric acid and Sodium chlorite must be placed separately, strict managementand make a leak emergency measures. | Waterproof, moisture stacked ,without safety measures |
| 5 | Raw materials for corrosion | Hydrochloric acid is a strong volatility and corrosive, affiliated electrical equipment, pumps, equipment room doors and other metal materials | No corrosive |
| 6 | Raw material safety | Sodium chlorite is flammable and explosive materials | Without any security risks |
| 7 | safety supervision | No national standard security administration of Work Safety performance standards, unable to meet the requirements of safety supervision | No |
| 8 | License | Health supervision department approval to wade document | Health supervision department approval to wade document |
| 9 | Storage | The gas generated can not be saved | Room temperature , closed, dark , plastic PE containers saved for a long save time. |
| 10 | Available chlorine concentration | CLO2+CL2 Mixed gas | 0.8% liquid ( sodium hypochlorite solution with low concentration of volatile) |
| 11 | Finished state | A strong irritant gas asphyxiation ,
Highly toxic | Light yellow transparent liquid, little irritating odor |
| 12 | Finished security | Must be prepared to deal with the strict anti-leak, emergency measures of leakage, or easily to cause accidents. | Liquid disinfection, diluted with water rinse when leakage, no security of risks. |
| 13 | Stability | Gas, can not be saved | Stable low concentration of sodium hypochlorite solution can be stored for a long time. |
| 14 | Mechanism | CLO2+CL2 | HOCl |
| 15 | Dosing method | Ejector siphon dosing of chlorine, the regulation can not be variable, fixed amount of chlorine | Accurate metering pump pressurized metered dosing, through the pipe network can be at any point the plant area, with the flow, residual value linkage form a closed loop metering pump flow is automatically adjusted to achieve the frequency variable dosing of chlorine. |
| 16 | Dosing accuracy / convenience | Siphon dosing of chlorine, accuracy is poor, it can not be precise metering control | Accuracy and can be administered using a smart device for precise measurement of flow rate based on the pipe network + line chlorine dosing, high degree of automation, enabling automatic intelligent inverter precise control, high degree of convenience. |
| 17 | The contact time with water | ≥30min | ≥30min |
| 18 | Leak prevention measures | Must be strictly set the leakage of chlorine absorption device | No special protective measures in the event of leakage , just use a lot of water to flush diluted |
| 19 | Leak harmful levels | Gaseous state, once leak is easy to cause large-scale diffusion, and serious social harm consequences | Liquid state, and the leakage of the liquid can be diluted then into the sewage pipes |
| 20 | Disinfection
By-products | Perchlorate chlorite must be strictly controlled, easily exceeded and leading to contamination of the water quality | Highly secure disinfection products |
| 21 | safety | Reaction leak may exist , must be prepared once the leakage of chlorine emergency plan and related measures, otherwise may threaten personal safety. | Safer , no risk of leakage |
| 22 | life service | About five years |
The whole life of more than 20 years , the electrode life more than 8 years. |
