New approaches are needed to reduce emission of contaminants of emerging concern (CECs). Some sources contribute strongly to such emissions, which has driven the focus of PRESAGE on innovative decentralized wastewater treatment (WWT). An integrated analysis of the behaviour of organic micropollutants (OMPs), antibiotic resistant microorganisms and genes (ARMs/ARGs), pathogens and viruses …
The main goal of this Research Project is to establish the fundamental bases to apply the biorefinery concept to a biological wastewater treatment plant, with generation of bioenergy and high value-added products. Such conception is based on the use of anaerobic reactors as the core technology in a wastewater treatment plant, mainly because this process generates a broad spectrum of organ…
Mass spectrometry is a method for identifying the different atoms that compose a substance. A mass spectrometer bombards a substance with electrons to produce ions, or electrically charged atoms. The ions cross a magnetic field that curves their trajectories in different ways, depending on their mass. The field separates the ions in a pattern known as the mass spectrum. The mass and the c…

In parallel with the advances and achievements achieved in modern societies through technical-scientific development, several problems related to human and environmental health have arisen as a result of the insertion of certain groups of molecules, compounds or substances that did not previously exist in environmental compartments, such as for example. eg water resources, which are then …
Human and veterinary drugs, natural hormones, cosmetic and personal hygiene products, disinfection products, pesticides and others make up the diverse group of MPOs. Due to analytical advances in recent decades and the high consumption of these molecules, several observed in significant concentrations in sanitary sewage. Due to the persistence of some organic micropollutants (MPOs) in con…
When released into the environment, pharmaceuticals can cause toxic effects and are liable to bioaccumulate in different organisms even at low concentrations. Thus, these emerging contaminants need to be removed in effluent treatment plants and anaerobic reactors, which have already shown potential for degradation, especially in the acidogenic phase. In this context, the project presented…

This study has as main focus the elaboration of a diagnosis and to propose actions for maintenance and improvement of the quality of the waters in an inhabited area within an area of Atlantic Forest, under the domain of the Instituto Terra Luminous (ITL). As it is a place characterized by having a seasonal generation of sewage and by being located in a preserved area, the common sewage tr…
Researches for renewable energy sources is increasing considerably nowadays, due to a possible shortage of fossil fuels in the future. In this sense, a promising alternative for clean energy is the treatment of domestic or industrial effluents using the anaerobic digestion process in bioreactors, in which microorganisms degrade complex organic matter and converts it into biogas, hydrogen …
Vinasse, a by-product of sugarcane processing, is a source of nutrients such as calcium, magnesium and potassium. For that reason, its main destination is the fertigation. However, vinasse has high concentration of solids and organic matter, acidity and a high sulfate content, which can affect the productive quality of the soils. Therefore, the previous treatment of vinasse before its use…

The major challenge in the stability and sustainability of anaerobic membrane reactors (AnMBR) operation is the membrane fouling. The common fouling control strategies in some cases are not enough to prevent fouling or to avoid the physical and chemical cleaning. It can cause interruptions in the process and additional expense with the membrane cleaning procedures. Sugarcane vinasse has i…
Researches for renewable energy sources are increasing nowadays, due to a possible scarcity of fossil fuels in the future. In this context, a promising alternative for clean energy is the treatment of domestic or industrial effluents using the anaerobic digestion process in bioreactors, in which microorganisms degrade complex organic matter and convert it into biogas, hydrogen or methane.…
Sugarcane vinasse, a byproduct of ethanol production, is currently being used as a fertilizer in the agricultural sector in Brazil. However, fertirrigation in excess and for long periods has caused environmental problems such as soil acidification and contamination of ground and surface water, among others. Classical ecotoxicological assays (survival and reproductive endpoints) have been …
The relevance of fundamental research on how a micropollutant is biologically converted into less toxic and persistent chemicals is the first step to apply biochemical knowledge on industrial processes. Even though Tetrabromobisphenol A (TBBPA) is the most used flame retardant worldwide and is often detected in wastewaters and water bodies, its biodegradation is poorly understood. The com…
The production of VFAs from organic wastes and residues by anaerobic fermentation is a promising technology and the use of microbial mixed culture fermentation is encouraged due to its various operational and economic advantages. The main limitation that prevents its industrial applicability is a lack of precise understanding of how different organic fractions are biotransformed into diff…
