Technology description

Poul-AR® pre-treats chicken manure before going into a (CSTR/thermophile) digester. The treatment consists of
mixing poultry manure and digestate from the digester, whereby grit, other contaminants as well as the ammoniacal nitrogen are removed from the mixture. The end product can then be fed to a (thermophilic) manure digester without causing anaerobic digestion problems. With the Poul-AR® installation up to 80% of the nitrogen is removed, making the substrate useable in a mono-poultry manure digester (or a co-fermenter).  This makes the system interesting for large poultry farms or clusters thereof. In addition, in terms of biogas production, chicken manure is comparable to maize. Replacing maize with chicken manure can therefore bring considerable economic and ecological benefits. The Poul-AR pre-treatment consists of 2 steps: (1) the ammonificiation, a batch process (24h) in which the ammonia is set free from the manure. (2) the de-ammonificiation, where the ammonia is stripped from the manure (and washed with an acid to produce N-fertilizers).
