Hi,
I'm a student from Potsdam - University, Germany, and I need some
informations about :
*deep-shaft - technology ; clean up wastewater (Tiefschachtverfahren zur
kommunalen Abwasserbeseitigung),
*airlift systems (in bezug auf das Verfahren)
*biofilter / solid bed bioreactors (Festbett - Bioreaktoren).
A few installations of this systems where made in the ex - GDR, I think
between 1982 and 1989. I hope, that somebody is able to help me - Thanks
a lot!!!
