Abstract

Sludge management is a complex problem, as the environmental norms and regulations are more and more restrictive. From this point of view, wastewater treatment must be associated with valorization and/or controlled storage of the resulted sludge. Besides these norms, during the normal operation, social, economical and other legal criteria must be considered. Bioaugmentation is o process by which microorganisms degrade (metabolize) the organic pollutants from wastewaters and neutralize their toxic effect. There is involved a multitude of microorganisms species (a ?bacterial cocktail?), which disappear during the anaerobic fermentation. These mainly indigenous bacteria degrade carbohydrates, partially or totally, and the result of their activity is environmental friendly, consisting of carbon dioxide, water and non-toxic substances. The paper presents a comparative study of the quality indicators of the treated wastewater with and respectively without the use of bioaugmentation in a municipal treatment plant. There are presented the results of six months monitoring period, regarding the evolution of physical and chemical parameters of treated wastewater and resulted sludge.
