The biological treatment of wastewater can be done by several processes, most of which promote the degradation of organic matter with the consequent formation of biomass (sludge).Nitrogen and phosphorus are partly incorporated into biomass and the remainder must undergo further treatment for removal. Nitrogen is converted to nitrogen gas in the combined process of nitrification followed b…
The objective of this research is to study a simple configuration of a biological reactor with anaerobic, aerobic and anoxic zones associated with inactivation of microorganisms and oxidation of odoriferous compounds. A reactor with compartments separated physically by system of gas collection will be assembleded, which will provide the use of the biogas from the aerobic zone as electron …
The aim of this project is the recovery of nutrients and carbon from concentrated black water (toilet water) while producing a valuable algal biomass product that can be used as fertilizer and a final liquid effluent that can be reused. This will be achieved by collecting the black water and treating it in an upward-flow anaerobic sludge blanket (UASB) reactor followed bya photobioreactor…

The increased concentration of nutrients, from anthropic activities, has increased the eutrophication in the aquatic environments and one of the consequences of the process is the excessive growth of microalgae. During the growth of the biomass, there is the release of the organic matter commonly known as Algal Organic Matter (AOM), being released by algae due to metabolic activity and/or…
Anaerobic sewage treatment has advantages due to low sludge production, low implementation and operation costs and long cell retention times with short hydraulic detention times. However, it is ineffective in removing nutrients such as nitrogen, requiring other forms of treatment to comply with legislation when the final disposal of effluent. One of the forms of biological nitrogen remova…
Algae are present in almost all aquatic environments, making them one of the most characteristic organisms on Earth. In the last years, several applications have been proposed, among them, the use in agriculture as biofertilizer and in the tertiary treatment of the sewage. In a scenario of increasing food demand and reduced soil fertility due to the indiscriminate use of synthetic fertili…
Globally, aquatic ecosystems have been subjected to a wide variety of degradation forms. Sewage is considered one of the main sources of water bodies' pollution, contributing significantly to organic matter and nutrients loadings, as well as pharmaceuticals and pathogenic microorganisms. In terms of sanitation, black water corresponds to the effluent collected from toilets, basically cont…

Microalgae cells and algogenic organic matter (AOM) are natural sources of high concentrations of dissolved organic carbon (DOC) and nitrogen. This composition shows their potential to form disinfection by-products (DBPs) after the disinfection process, which poses a health risk to the water consumers. Despite the importance of this topic, few studies have focused on DBP formation from AO…
The research project abroad aims to study the mechanism behind alkaline flocculation (harvesting) of the freshwater microalgae Chlorella sorokiniana, cultured in defined mineral medium and black water. This harvesting method is considered a cheap way of biomass separation and it is based on either spontaneous or forced pH alteration. The pH shift to alkaline regions (pH 9-12) induces prec…
Reclaiming wastewater has been recognized as a vital component of sustainable water resources in recent decades because communities across the world face water supply challenges due to increasing demand, drought, depletion and contamination of groundwater, and dependence on single sources of supply. Thus, water reclamation, recycling, and reuse address these challenges by resolving water …
