Membrane filtration, stripping and scrubbing of manure and digestate for ammonium sulphate production

This technology combines mechanical separation, membrane filtration and ammonia recovery to treat digestate of livestock manure.

Producing fertilisers and clean water from manure – the process

The process includes:

  1. Mechanical separation of the feedstock to separate the solid and liquid fraction.
  2. Advanced filtration of the liquid fraction via filtration
  3. Ammonia recovery through stripping and scrubbing which results in the ammonium sulphate product.
  4. Reverse osmosis for water purification

 

The final product:

  • Ammonium sulphate
