The separation of ammonia from aqueous solutions by diffusion through membranes comprises the diffusion of gaseous ammonia through the pores of a non-wettable membrane into an acid, in which it is converted to non-volatile ammonium. For an effective separation of ammonia the pH-value and/or the temperature have to be increased to such a degree, that the ammonium, contained in the waste-water, is converted mainly to ammonia. Experimental plants were constructed on the basis of process parameters determined by laboratory tests, and tested for the treatment of liquid manure and of waste-water from power plants. The separation of ammonia from liquid manure was possible but couldn't be performed economically. On the other hand the treatment of w...
