VEAS and YARA (http://www.circulary.eu/project/yara-recovery/):
- Ammonia stripping represents a feasible and costefficient solution to remove ammoniacal N from the AD-filtrate water of a municipal WWTP.
- Some 350 – 500 Mt of N / year is recovered from the wastewater, yielding a concentrated (54% w/w) ammonium nitrate solution of some 4,000 Mt / year.
- The required installations are compact and can easily be expanded if the water treatment capacity would require further expansion.
