Utilization of the Protein Fraction Nitrogenous Compounds

The Henry s law constant estimate will probably have to be determined for each specific situation because its value can be masked by mass transfer limitations. 

The ammonia compounds in the digestate can be recovered using a process called ANASTRIP (Deublein and Steinhauser, 2008). In ANASTRIP, the ammonia-bearing digestate is stripped with a gas, which is subsequently scrubbed with a gypsum (CaSO H O) solution which produces ammonium sulfate [(NH )2SO ] (Deublein and Steinhauser, 2008) via the reaction
