<p>A process and an apparatus for continuous removal of ammonia and phosphate from liquid manure by a stripping process. The remaining watery fraction from which the ammonia and phosphates are removed is filtered by a plot of land that acts as a filter for, mainly, the remaining organic material. The ammonia and phosphates are recovered and can be sold as a fertiliser. The apparatus comprises a stripper/absorber (4) to which the manure can be supplied and where, with the addition of lime (5), ammonia and phosphate can be removed from the manure, the stripper/absorber containing a first contacting unit, for bringing the liquid manure into contact with a flow of warm air to strip carbondioxide and part of the ammonium from the manure.</p> |
