Problems with removing ammonia nitrogen using MVR
Thread Content
An industrial wastewater has an ammonia nitrogen level as high as 10,000 mg/L, primarily in the form of NH4Cl. Can installing an MVR unit now to remove NH4Cl ensure that the ammonia nitrogen content in the steam condensate is less than 10 mg/L?
I have tuned an ammonium chloride MVR unit in Suzhou; I’m not sure what the evaporation capacity of yours is.
There are MVR evaporation units specifically designed to remove ammonia nitrogen, which can reach levels of up to 10,000 mg/L and is primarily present in the form of NH4Cl. I think I’m going in the wrong direction. If it is more than 5% NH4CL, I think it makes sense to use evaporation treatment. However, it is impossible to keep the ammonia nitrogen concentration in the effluent below 10 mg/L. Removing ammonia nitrogen at a concentration of 10,000 mg/L through evaporation is neither scientific nor economical; as for the economic aspects, they are obviously unfavorable, since evaporation is a process with high operating costs. Speaking again about the scientific aspects, ammonium chloride is a substance that decomposes easily; when using evaporation, the ammonia nitrogen concentration in the condensed water will definitely be higher than 10 mg/L. It is recommended to use methods such as stripping, degassing membranes, and special reverse osmosis to remove ammonia nitrogen. Personal advice is for reference only.

We manufacture ammonia stripping towers and ammonia vaporization towers. Options are available for ammonia nitrogen concentrations below 3000; contact QQ874941228 for discussions
Our company is working on a project related to waste leachate; the treatment process involves MVR evaporation in the initial stage, followed by RO low-pressure reverse osmosis. This approach enables the ammonia nitrogen level to be kept below 10 MG/L. If you are interested, feel free to send me a private message
