Potassium fertilizer out of liquid manure: LEWA Prize for Daniel Frank

07/23/2014

The LEWA Prize is awarded every year for outstanding achievements at University of Stuttgart. This year, the prize goes to the doctoral candidate Daniel Frank for his research at the Institute of Interfacial Process Engineering and Plasma Technology (IGVP). He found out, how potassium can be recovered from liquid manure for agricultural fertilization.

Potassium salts are used as fertilizers for plants in agriculture, because they accelerate photosynthesis and increase the resistance to diverse environmental influences and to vermin. Conventional liquid manure contains larger quantities of potassium.

For that reason, Daniel Frank’s dissertation deals with the question, how potassium can be recovered from liquid manure. In the laboratory, the prospective academic succeeded in separating the potassium-magnesium-phosphate from the liquid manure.

For his research, Daniel Frank was awarded with the LEWA Prize, which is endowed with 2,000 Euros. Since 1995, the prize is awarded annually for outstanding and innovative achievements in the fields of process engineering and cybernetics at University of Stuttgart.
