Treatment solutions for high-chlorine wastewater
Thread Content
Has any expert dealt with wastewater containing high levels of chlorine? Give me some advice! Thank you!
When the chloride ion concentration is above 5000, biological treatment is virtually ineffective; especially when it exceeds 10000, the use of biological methods can be ruled out. High-salinity wastewater can be treated by electrolysis, micro-electrolysis, or strong oxidation methods; it can also be treated by incineration, although this method causes severe corrosion.
Personally, I think electrolysis technology could be considered; the chlorine gas produced can also be collected and utilized. What is the nature of the wastewater you need to treat? Could you list the relevant parameters?
I’m puzzled; in industrial applications, we have handled wastewater with chloride levels as high as 10,000 ppm. The key is the strain.
Could LZ explain? Does the wastewater contain chloride ions or chlorine gas? If it’s chloride ions, to what extent do they need to be removed? If very high standards are required, and the water quality and pH are under control, then reverse osmosis is a good option (provided that financial resources are sufficient). Another option is electrodialysis; it’s my top recommendation, as it offers a decent desalination efficiency
The wastewater contains chloride ions at a concentration of 26,000 mg/L. To what extent can this waste water be treated using reverse osmosis or electrodialysis, and what will be the concentration of chloride ions in the treated water? What process can be used for reuse?
Saltwater containing more than 15% sodium chloride can be considered for reuse; if an ion-exchange membrane electrolyzer is available, it can be fed back into the electrolyzer. After high-temperature and high-pressure catalytic oxidation, as well as adsorption and ion exchange, the TOC
