Prof. Ulrich Stottmeister

The recommendations of the
microbiologists
1. Optimum range for activity of bacteria is pH 7-8!!.
2. A new bacterial community will be
established after flocculation
3. Destroyed „bond residues“ makes organics
bioavailable,
4. Complex community of phyto- and zooplankton will support
biodegradation of organic compounds and removal of
ammonia
5. Methanogenesis by degradation of organic compounds
should be happen in the depth (+ iron /humate
respiration)
