The result was predictable for me, but disappointing for those who at the time (1997...) had high hopes for water treatment: they had the grandiose idea of adopting processes that had proved successful elsewhere without question (even the wooden houses built in the Norwegian style were such a crazy idea...). Hence the idea of my research. It turned out, of course, that a process based on the interaction of certain bacteria only works WITH THOSE bacteria. Their occurrence and activity is naturally different in this country than in the north. Surprise. Unsuitable experiment.

As a result, it was a lengthy process to adapt the process in question for our latitudes. With the result that in the end it was too expensive and ineffective.

In the meantime, process engineering is always based on regional conditions, but the trial-and-error mentality is here to stay...
