Ways of innovation for the reduction of excess sludge (W.I.R.E.S.)

Objective

Municipal wastewater treatment is tightly linked with the production of sludge. The excess sludge disposal becomes thus one of the major challenges for the next decade, in terms of social, environmental, economical issues. The project aims at preventing biomass formation rather than destroying already formed sludge, by the application of "stresses" in the water treatment train. Selected promising routes include direct or indirect limitation of biomass growth (uncoupling agents, application of stresses), enhancement of grazing by protozoa and use of anaerobic bacteria. Those researches will be supported by fundamental studies on bacterial metabolic response to stresses and population dynamics and shifts. Expected results are a better knowledge of the biological process and the availability of technico-economic data for the reduction of sludge production together with the maintenance of effluent quality standards.
