High ammonia nitrogen wastewater refers to the high content of NH₃ in the water, now commonly used high concentration of ammonia nitrogen wastewater treatment process are: membrane deamination, biological method, blowing off the vapor extraction method, chemical precipitation, folding point chlorination, ion exchange, reverse osmosis, etc., the high concentration of ammonia nitrogen wastewater treatment process specific comparison is shown in the table below:

   In summary, membrane deamination method overcomes the problems of other processes such as limited concentration of ammonia nitrogen treatment, limited application at high COD, high energy consumption, expensive operation, secondary pollution, unstable performance, etc., and it is a well-established process for the treatment of high-concentration ammonia nitrogen wastewater.
