What types of wastewater containing ammonia nitrogen are appropriate for deamination using membrane technology?

When considering the concentration of ammonia nitrogen in wastewater, it is economically viable to use membrane deamination when the concentration ranges between 300mg/L and 10000mg/L". However, if the ammonia nitrogen content in wastewater is low, it is more cost-effective to use biochemical methods. Using membrane deamination to treat low-concentration ammonia nitrogen wastewater will result in a lower concentration of ammonium sulfate absorption solution, which in turn will increase the cost of subsequent treatment. Conversely, if the concentration of ammonia in wastewater is too high, the consumption of acid and alkali will be significant, which is less economical than steam stripping.

It's worth noting that the use of membrane deamination also necessitates certain quality requirements for the wastewater being treated. For example, the oil content in the water must not exceed 2mg/L, and the surface tension of the water should not fall below 40uN/m.
