METHOD AND PLANT FOR TREATMENT OF ORGANIC WASTE MATERIAL

摘要

The present invention relates to a method of and a plant for treatment of an organic waste material containing an aqueous phase and a solid phase. The invention involves separation and purification of the organic waste material. The organic waste material may be manure from livestock production being separated into an enriched solid phase containing nutrients, such as ammonium, phosphor and potassium, and a purified aqueous phase. It is preferred to introduce and subject the organic waste material to at least one coagulant, at least one flocculating agent and to allow association between negatively charged solid material and cations of the organic waste material. The invention is capable of obtaining a dry matter content of the organic waste material. The invention is capable of obtaining a dry matter content of the organic waste material below 20% wt.
