Vitamin addition in biological wastewater treatment

Vitamin addition in biological wastewater treatment

Vitamin supplementation is advertised in wastewater treatment to compensate for a deficiency of growth factors and thereby increase sludge activity and purification efficiency. Addition of vitamins of the 13complex was tested with activated sludge from 5 plants and compared to municipal sludge. Auxo...

Zusammenfassung:Vitamin supplementation is advertised in wastewater treatment to compensate for a deficiency of growth factors and thereby increase sludge activity and purification efficiency. Addition of vitamins of the 13complex was tested with activated sludge from 5 plants and compared to municipal sludge. Auxotrophy of bacteria isolates turned out to be compensated to most cases by vitamin producers in the activated sludge biocenoses.
