Notes:
The use of ‘selectors’to control the filamentous bacteria which promote bulking in activated sludge is a well-established concept. However, their use as a control measure for stable foams is still to be optimized. This paper presents the results of a preliminary investigation into the use of selectors at three sewage-treatment works where stable foams occurred regularly. Chemical and biological data are reported together with the redox potentials in the selector zones. Taken overall, the results suggest that selectors cannot be designed or built on an ad hoc basis if the foam-producing filaments are to be controlled.
