Abstract

A techno-economic comparison of membrane technologies (microfiltration (MF), nanofiltration (NF)
and reverse osmosis (RO)) and physico-chemical operations (struvite precipitation and ammonia
stripping) for obtaining nutrient-rich fractions from biogas digestates, has been carried out. Four
different treatments for the digestate including solid-liquid separation using a decanter centrifuge or a
screw press are compared. A screw press followed by membrane technologies (treatment B) shows the
best economical potential with a total potential of 4.9€/t feed.
