The performance of gas-permeable membrane (GPM) technology for nitrogen (N) recovery from digestate with
subsequent struvite formation is evaluated in this work and compared with the recoveries obtained by centrifugation or direct struvite formation. Nearly 68% of the digestate N was recovered using GPM technology, which was almost 2-times higher than the recoveries achieved in solid form by centrifugation or direct struvite formation. In addition, the use of GPM as a first stage improved the P recovery by struvite formation from the N-trapping digestate up to 100%.
