Recovery of ammonia from industrial waste water. On the basis of new ecological findings, waste waters containing residual amounts of ammonia or ammonium ion formerly regarded as safe must now be classified as a serious potential hazard for the environment. Since new limits for ammonia/ammonium in waste waters are to be expected in the near future, considerable research and development work is currently being invested in the separation and recovery of ammonia. The present article considers the ecological problems relating to ammonium and states the sources of such effluents. Moreover, possible separation processes and recovery methods are reviewed and the pros and cons of the individual processes compared.
