Thats not entirely clear yet, it depends on progress with current master thesises, and wich ones require a more in depth look.
In june i finish my Master of science in applied engineering : Biochemistry".
Considering my scores, general knowledge and motivation on wastewater threatment engineering, i am first in line for a great master thesis the university is currently negotiating with a company. Its basically about the usage of more advanced techniques in the biological purification for a company for whom they could be a solution. My thesis would be about implementing the method in a reactor on lab scale, finding the correct parameters and means of implementation,and then design a pilot wich could run for a year at the company, to validate the method.
Now the technique i'm allowed to use is the one wich would have the best impact, but its not the only technique. When i finish my master, there is going to be 1 or 2 pdh's about in depth study of the best performing technique.
As of current i'm thinking suspended granular de/nitrification sludge will make it. We'll see next year.
