Abstract
Ammonium salts Hollow fibre Hydrophobic membrane Nutrient recovery Urban wastewater Water transport The nitrogen load on urban wastewater should be considered as a secondary resource for nitrogen-based fertilizers. From this point of view, ammonia-rich streams obtained from a regeneration step with zeolites using 70-80 g NaOH/L could contain up to 3.5-4.5 g NH3/L as well as other ionic species (Na+, K+, Ca2+, Mg2+) and dissolved organic matter (DOM). Thus, they could be treated to obtain a valua...
