Online control in sodium hypochlorite production
Thread Content
Sodium hypochlorite is inevitably produced as an accompanying by-product in chlor-alkali production; controlling temperature and the amount of chlorine supplied is key. In actual production, what are some good methods for monitoring whether the concentration of sodium hypochlorite is within acceptable limits, such as using online pH analyzers to track residual alkali levels?
For online ORP detection and online concentration detection, online concentration detection is the more reliable option
The online ORP reading is relatively accurate; it should be calibrated regularly. Due to the high alkalinity, the error for PH is very large
ORP monitoring is also not good, as there are too many influencing factors.
Our company has newly developed an online free alkali monitoring device for hyposodium. Those interested can contact me at 13565896883; the WeChat ID is the same
